SLC12A7 Antibody

What is SLC12A7 and why is it relevant to biomedical research?

SLC12A7 (Solute Carrier Family 12 Member 7) is a 1083 amino acid transmembrane protein that primarily functions as an electroneutral potassium-chloride cotransporter. Its physiological role involves regulating cell volume through trans-membrane potassium and chloride transport. Beyond its basic function, SLC12A7 has gained significant research interest due to its emerging role in cancer biology. Recent studies have demonstrated that SLC12A7 is overexpressed in several cancer types, including cervical, ovarian, and breast cancers, where it promotes tumor cell growth both in vitro and in vivo . SLC12A7 has also been implicated in tumor cell migration and invasion by colocalizing with ezrin (a membrane cytoskeleton linker) at the lamellipodia of tumor cells. The overexpression of SLC12A7 correlates with local tumor invasion, lymph node metastases, and poor clinical outcomes, making it an important target for cancer research .

What types of SLC12A7 antibodies are currently available for research applications?

Several types of SLC12A7 antibodies are available for research applications, varying in their target epitopes, host species, clonality, and conjugation status. Current options include:

• Polyclonal antibodies targeting different amino acid sequences (e.g., AA 11-117, AA 1-70, AA 89-117, AA 845-1056)

• Antibodies with different host species, predominantly rabbit and mouse

• Conjugated variants including FITC, biotin, and HRP-conjugated antibodies for specific applications

• Antibodies targeting specific domains of the protein, including N-terminal and C-terminal regions

The selection of an appropriate SLC12A7 antibody depends on the specific research application, target species, and experimental conditions. For immunohistochemistry and immunofluorescence studies, antibodies targeting amino acids 11-117 have been documented to yield reliable results .

What are the standard applications for SLC12A7 antibodies in research settings?

SLC12A7 antibodies are employed in multiple research applications, each providing distinct information about protein expression, localization, or function:

• Immunohistochemistry (IHC): Used to detect SLC12A7 expression in tissue sections, allowing visualization of protein expression patterns in different cell types and disease states. Typical dilutions range from 1:20 to 1:200 .

• Immunofluorescence (IF): Enables high-resolution visualization of SLC12A7 localization within cells, particularly useful for colocalization studies with proteins like ezrin. Recommended dilutions are 1:50 to 1:200 .

• Western Blotting: Facilitates quantitative assessment of SLC12A7 protein expression levels in cell or tissue lysates, critical for comparing expression across experimental conditions .

• ELISA: Allows sensitive quantification of SLC12A7 protein levels in solution .

• Immunocytochemistry (ICC): Permits analysis of SLC12A7 expression and localization in cultured cells .

When designing experiments using SLC12A7 antibodies, researchers should validate specificity using appropriate positive and negative controls and optimize protocols for their specific experimental conditions.

How should SLC12A7 antibodies be stored and handled to maintain optimal performance?

Proper storage and handling of SLC12A7 antibodies are critical for maintaining their performance and experimental reproducibility. Based on manufacturer recommendations:

• Store antibodies at -20°C or -80°C upon receipt, avoiding repeated freeze-thaw cycles which can degrade antibody quality .

• Aliquot antibodies into smaller volumes before freezing if multiple experiments are planned over time.

• Most SLC12A7 antibodies are supplied in liquid format with preservatives such as 0.03% Proclin 300 and stabilizers like 50% glycerol in 0.01M PBS (pH 7.4) .

• When handling the antibody, note that some preservatives like ProClin are hazardous substances that should be handled by trained personnel with appropriate safety precautions .

• Prior to use, allow antibodies to equilibrate to room temperature and centrifuge briefly to collect contents at the bottom of the tube.

• Follow manufacturer-specific recommendations for each antibody, as optimal storage conditions may vary slightly between products.

Maintaining a laboratory record of antibody performance across different lots can help identify any batch-to-batch variations and ensure experimental consistency.

What methodological approaches can be used to validate SLC12A7 antibody specificity?

Validating antibody specificity is essential for generating reliable and reproducible research results. For SLC12A7 antibodies, several complementary approaches can be employed:

• Genetic manipulation controls: Compare antibody staining between:

  • Cells with enforced SLC12A7 overexpression (e.g., SW-13 cells transfected with SLC12A7 expression vectors as described in the literature)

  • Cells with RNAi-mediated SLC12A7 knockdown (e.g., NCI-H295R cells which have robust endogenous expression)

  • Parental cells without genetic manipulation

• Western blot validation: Verify that the antibody detects a band of the expected molecular weight for SLC12A7 (~120-130 kDa) with minimal non-specific binding. Include positive controls (cells known to express SLC12A7) and negative controls (cells with negligible SLC12A7 expression) .

• Immunoprecipitation followed by mass spectrometry: This approach can confirm that the antibody is capturing the intended target protein.

• Peptide competition assay: Pre-incubate the antibody with the immunizing peptide (e.g., the recombinant human SLC12A7 protein fragment corresponding to amino acids 11-117) before application to samples. This should significantly reduce or eliminate specific binding.

• Cross-reactivity assessment: Test the antibody against samples from multiple species if cross-reactivity is claimed by the manufacturer. Some SLC12A7 antibodies are reactive with human, mouse, and rat proteins .

Comprehensive validation increases confidence in experimental results and should be reported in methods sections of publications.

What are the optimal sample preparation protocols for detecting SLC12A7 in different experimental systems?

Sample preparation protocols should be tailored to both the experimental system and the detection method:

For Immunohistochemistry (IHC):

• Fixation: 10% neutral buffered formalin fixation for 24-48 hours is typically suitable.

• Antigen retrieval: Heat-induced epitope retrieval using citrate buffer (pH 6.0) or EDTA buffer (pH 9.0) is often necessary to expose epitopes masked during fixation.

• Blocking: Use 5-10% normal serum (matching the species of the secondary antibody) to reduce background staining.

• Primary antibody incubation: Apply SLC12A7 antibody at dilutions of 1:20-1:200 as recommended , typically overnight at 4°C.

For Immunofluorescence (IF) on cultured cells:

• Fixation: 4% paraformaldehyde for 10-15 minutes at room temperature.

• Permeabilization: 0.1-0.5% Triton X-100 for 5-10 minutes to allow antibody access to intracellular epitopes.

• Blocking: 5% bovine serum albumin (BSA) or 5-10% normal serum for 1 hour.

• Primary antibody incubation: Apply SLC12A7 antibody at dilutions of 1:50-1:200 , typically overnight at 4°C.

• Counterstaining: DAPI for nuclear visualization as used in published protocols .

For Western Blotting:

• Lysis buffer: RIPA buffer supplemented with protease inhibitors is suitable for extracting membrane proteins like SLC12A7.

• Sample preparation: Heat samples at 70°C (not 95-100°C) to avoid membrane protein aggregation.

• Gel selection: Use mini-PROTEAN TGX gels or similar for effective separation of the large SLC12A7 protein (~120-130 kDa) .

• Transfer conditions: Optimize for large proteins, potentially using lower methanol concentrations in transfer buffer.

• Detection: Use enhanced chemiluminescence with suitable exposure times to avoid over-saturation .

Optimization of these protocols for specific experimental conditions may be necessary to achieve optimal results.
