SLC30A10 Antibody, Biotin conjugated

What is SLC30A10 and why is it an important research target?

SLC30A10 (Solute Carrier Family 30, Member 10) functions as a cell surface-localized manganese efflux transporter that reduces cellular manganese levels and protects against manganese-induced toxicity . Also known as Zinc transporter 10 (ZnT-10), this protein has gained significant research interest because mutations in the SLC30A10 gene have been linked to a familial parkinsonian syndrome . Research has demonstrated that parkinsonism-causing mutations in SLC30A10 can block trafficking and efflux activity of the protein, causing neurons to exhibit enhanced sensitivity to manganese toxicity . These findings provide important mechanistic insights into this poorly understood neurological disorder, making SLC30A10 a valuable target for neurological and toxicological research.

What applications are biotin-conjugated SLC30A10 antibodies suitable for?

Biotin-conjugated SLC30A10 antibodies are versatile research tools that can be utilized in multiple experimental applications. Based on available product information, these antibodies are primarily designed for ELISA applications . The biotin conjugation enables high-sensitivity detection when used with streptavidin-based detection systems. For instance, in ELISA kits specific for SLC30A10, samples are added to microplate wells coated with a capture antibody, followed by addition of the biotin-conjugated antibody specific to SLC30A10, and then detection using an avidin-HRP (horseradish peroxidase) complex . This configuration allows for sensitive quantification of SLC30A10 with detection ranges typically between 0.16-10 ng/mL and sensitivities around 0.063 ng/mL .

How should SLC30A10 antibodies be stored to maintain optimal activity?

Proper storage of SLC30A10 antibodies, including biotin-conjugated versions, is crucial for maintaining their effectiveness in experimental applications. According to product specifications, biotin-conjugated SLC30A10 antibodies should generally be stored at -20°C for long-term preservation . Some products may be stored at -80°C for extended periods. Most antibody formulations contain preservatives such as 0.03% Proclin 300 and stabilizers like 50% glycerol in appropriate buffers (typically PBS at pH 7.4 or TBS) . It's important to avoid repeated freeze-thaw cycles, as these can degrade antibody performance. For working solutions, temporary storage at 4°C is typically acceptable for up to one week, but for longer periods, aliquoting and freezing at -20°C is recommended . Always consult the specific product datasheet, as storage recommendations may vary slightly between manufacturers.

What species reactivity should be considered when selecting an SLC30A10 antibody?

Species reactivity is a critical consideration when selecting an SLC30A10 antibody for your research. Based on available product information, SLC30A10 antibodies exhibit varying cross-reactivity profiles depending on their design and the immunogen used. Many commercially available SLC30A10 antibodies are reactive with human samples , while some also demonstrate cross-reactivity with mouse and rat SLC30A10 . For example, the antibody described in search result is specifically designed to recognize an epitope of human ZnT10 (SLC30A10) but has been validated for use with mouse and rat samples as well. When planning experiments, researchers should verify the antibody's reactivity with their specific species of interest and consider testing the antibody on known positive control samples to confirm cross-reactivity before conducting full-scale experiments . This is particularly important when working with less common model organisms or when translation between animal models and human samples is a research objective.

Investigating manganese transport mechanisms using SLC30A10 antibodies involves sophisticated experimental designs that combine multiple techniques. Based on published research protocols, the following methodological approach is recommended:

• Mn pulse-chase assays: Transfect cells with SLC30A10 constructs (wild-type or mutant), treat with manganese (typically 500 μM for 16 hours), then chase in manganese-free media. Use biotin-conjugated SLC30A10 antibodies to immunoprecipitate the transporter and assess its association with manganese .

• Subcellular localization studies: Perform immunofluorescence with biotin-conjugated SLC30A10 antibodies and co-stain with markers for plasma membrane (Na+/K+ ATPase), endoplasmic reticulum (calnexin), or endosomes (Rab5). This approach revealed that SLC30A10 is primarily localized to the cell surface, consistent with its role as an efflux transporter .

• siRNA knockdown experiments: Use siRNAs targeting SLC30A10 (e.g., sequence AAC GCA GTC TTC CTC ACC GCG for rat SLC30A10) alongside control siRNAs, then quantify intracellular manganese levels by ICP-MS while monitoring SLC30A10 expression using the biotin-conjugated antibodies .

• Cell viability assays: After manipulating SLC30A10 expression or function, assess cell viability using MTT assays in the presence of varying manganese concentrations to establish the protective role of SLC30A10 against manganese toxicity .

• Manganese measurements: Perform ICP-MS analysis to quantify intracellular and secreted manganese levels, correlating these with SLC30A10 expression levels determined by immunoblotting or ELISA using biotin-conjugated antibodies .

This multifaceted approach has successfully demonstrated that SLC30A10 functions as a cell surface-localized manganese efflux transporter that protects against manganese-induced toxicity, and that parkinsonism-causing mutations disrupt this function .

What are the key considerations when studying disease-associated SLC30A10 mutations?

Investigating disease-associated SLC30A10 mutations requires careful experimental design and specialized approaches. Research has identified that mutations in SLC30A10 are associated with a familial form of parkinsonism characterized by manganese accumulation. When studying these mutations, researchers should consider the following methodological approach:

• Expression system selection: Human cell lines (HeLa, HEK293) or neuronal models (AF5) are appropriate for studying wild-type and mutant SLC30A10 proteins .

• Mutation verification: Sequence constructs expressing wild-type or mutant SLC30A10 (such as the Δ105-107 deletion) to confirm the presence of the intended mutations.

• Protein trafficking analysis: Use biotin-conjugated SLC30A10 antibodies in combination with subcellular fractionation or immunofluorescence to assess differences in localization between wild-type and mutant proteins. Research has shown that disease-causing mutations result in retention of SLC30A10 in the endoplasmic reticulum rather than proper trafficking to the cell surface .

• Functional assays: Compare manganese efflux capabilities between wild-type and mutant proteins using pulse-chase experiments and ICP-MS analysis. This approach demonstrated that the Δ105-107 mutation blocks the manganese efflux activity of SLC30A10 .

• Cell viability assessment: Conduct comparative viability assays (MTT) between cells expressing wild-type versus mutant SLC30A10 when exposed to manganese to establish functional consequences of mutations.

• Model organism validation: Extend findings from cell culture to model organisms (C. elegans has been used effectively) to validate the in vivo consequences of SLC30A10 mutations .

This systematic approach has revealed that parkinsonism-causing mutations in SLC30A10 block both trafficking and efflux activity of the transporter, leading to enhanced sensitivity to manganese toxicity in neurons and model organisms .

How can researchers effectively compare SLC30A10 with other SLC30 family transporters?

Conducting comparative studies between SLC30A10 and other members of the SLC30 family (ZnT family) requires sophisticated experimental design and specialized tools. Based on available research methodologies, the following approach is recommended:

• Co-immunoprecipitation studies: Use biotin-conjugated SLC30A10 antibodies to immunoprecipitate SLC30A10 and assess potential interactions with other SLC30 family members.

• Metal specificity determination: Compare the substrate specificity of different transporters using metal-specific fluorescent probes or ICP-MS analysis:
  a. For SLC30A10: primarily manganese transport
  b. For SLC30A3 (ZnT3): primarily zinc accumulation in synaptic vesicles

• Subcellular localization comparison: Use immunofluorescence with specific antibodies to compare localization patterns:
  a. SLC30A10: primarily cell surface localization
  b. SLC30A3: primarily cytoplasmic and synaptic vesicle localization

• Functional redundancy assessment: Use siRNA knockdown of individual transporters, followed by overexpression of other family members, to determine whether different SLC30 proteins can compensate for each other's functions.

• Disease relevance comparison: While SLC30A10 mutations are associated with parkinsonism , evaluate whether other SLC30 family members are associated with distinct pathologies.

This methodological approach allows researchers to establish the unique roles of different SLC30 family transporters in metal homeostasis and their specific contributions to cellular physiology and disease processes.

What are common troubleshooting strategies for weak or non-specific signals when using biotin-conjugated SLC30A10 antibodies?

When encountering weak or non-specific signals with biotin-conjugated SLC30A10 antibodies, researchers should implement systematic troubleshooting strategies:

  b. Testing alternative blocking agents (5% BSA, 5% normal serum, commercial blocking buffers)
  c. Adding 0.1-0.3% Tween-20 to reduce hydrophobic interactions

• Antigen retrieval for tissue sections: For IHC applications, test different antigen retrieval methods (heat-induced with citrate buffer pH 6.0, or EDTA buffer pH 9.0) to improve epitope accessibility.

• Signal amplification systems: For very low abundance targets, consider:
  a. Using tyramide signal amplification (TSA) with biotin-conjugated antibodies
  b. Employing poly-HRP streptavidin instead of standard streptavidin-HRP

• Sample preparation optimization: Ensure complete protein denaturation for Western blotting by adjusting buffer composition or heating conditions.

• Positive control inclusion: Always run a sample known to express SLC30A10 (such as cells transfected with SLC30A10 expression constructs ) alongside experimental samples.

• Endogenous biotin blocking: For tissues with high endogenous biotin (liver, kidney), use commercial biotin blocking kits before applying the biotin-conjugated antibody.

• Storage and handling verification: Confirm proper storage at -20°C and avoid repeated freeze-thaw cycles that can degrade antibody performance .

If problems persist after these optimizations, consider switching to an unconjugated primary antibody against SLC30A10 followed by a biotinylated secondary antibody, which sometimes provides better signal-to-noise ratios than directly conjugated antibodies.

How should researchers interpret conflicting results between different experimental methods when studying SLC30A10?

Interpreting conflicting results between different experimental methods is a common challenge in SLC30A10 research. When faced with discrepancies, implement this systematic approach:
