The antibody is validated for diverse techniques, with optimized dilutions and protocols:
The SLC12A3 antibody binds to the extracellular domain of the NCC cotransporter, enabling its detection in both intact and denatured forms. In Gitelman syndrome, mutations in SLC12A3 (e.g., p.M672I) cause exon skipping, leading to non-functional protein truncations . The antibody aids in diagnosing such conditions by identifying aberrant splicing or loss of protein expression.
Exon Skipping: Mutations like p.A356V and p.M672I disrupt splicing enhancers, causing exon 16 exclusion and non-functional NCC .
Functional Assays: The antibody is used in Xenopus oocyte systems to assess cotransporter activity, confirming loss of Na⁺/Cl⁻ uptake in mutant NCC .
SLC12A3 (Solute carrier family 12 member 3) functions as an electroneutral sodium and chloride ion cotransporter primarily expressed in distal convoluted tubules of the kidney. It serves as a key mediator of sodium and chloride reabsorption in the kidney . Recent research has revealed that SLC12A3 may also function as a receptor for the pro-inflammatory cytokine IL18, contributing to cytokine production including interferon gamma, interleukin 6, interleukin 18 and C-C motif chemokine ligand 2 . These dual functions make SLC12A3 a significant target for research in renal physiology, hypertension, and inflammatory processes. Mutations in the SLC12A3 gene are associated with Gitelman Syndrome, a rare genetic disorder characterized by electrolyte abnormalities .
Based on available research reagents, SLC12A3 Antibody, Biotin conjugated products typically share these specifications:
Biotin conjugation provides several methodological advantages for researchers. The biotin molecule attached to the SLC12A3 antibody enables strong binding to avidin and streptavidin, creating a versatile detection system with signal amplification capabilities. This conjugation strategy enhances detection sensitivity in assays like ELISA, immunohistochemistry, and flow cytometry . Additionally, biotin conjugation facilitates multiple detection options as researchers can use various labeled streptavidin conjugates (fluorescent, enzymatic, or metal-based) without needing secondary antibodies, reducing potential cross-reactivity issues. For multiplexing experiments where several targets need simultaneous detection, biotin-conjugated antibodies can be paired with differently labeled streptavidin reagents, allowing for more complex experimental designs than possible with unconjugated antibodies .
When designing experiments with SLC12A3 Antibody, Biotin conjugated, researchers should include these essential controls:
Positive control: Kidney tissue sections or lysates (particularly distal convoluted tubule-enriched samples) where SLC12A3 is highly expressed
Negative control: Tissues with minimal SLC12A3 expression such as lung and liver samples
Isotype control: Rabbit IgG-biotin at matching concentrations to assess non-specific binding
Blocking control: Samples pre-incubated with recombinant SLC12A3 protein (791-952AA) to demonstrate binding specificity to the immunogen
Secondary-only control: Omitting primary antibody but including streptavidin detection reagent to assess background
Research indicates that lung and liver tissues serve as appropriate negative controls for SLC12A3 detection based on published literature (PMID: 35591852) .
For optimal SLC12A3 detection in fixed tissue samples, researchers should consider a systematic approach to antigen retrieval optimization. Heat-induced epitope retrieval (HIER) using citrate buffer (pH 6.0) has shown efficacy for SLC12A3 antibodies in paraffin-embedded kidney sections. For challenging samples, researchers might consider:
Comparing multiple retrieval buffers (citrate pH 6.0, EDTA pH 8.0, and Tris-EDTA pH 9.0)
Testing retrieval times (10-30 minutes)
Evaluating different heating methods (microwave, pressure cooker, or water bath)
Optimizing cooling periods (immediate application vs. gradual cooling)
For membranous proteins like SLC12A3, detergent-assisted antigen retrieval can enhance accessibility. Adding 0.05% Tween-20 to retrieval buffers may improve staining by facilitating antibody penetration to membrane-embedded epitopes without disrupting biotin conjugation. Protease-induced epitope retrieval should be approached cautiously as it might damage the 791-952AA epitope region recognized by this antibody .
When addressing potential cross-reactivity of SLC12A3 Antibody, Biotin conjugated, researchers should implement multiple validation approaches:
Pre-adsorption experiments: Incubate the antibody with excess recombinant SLC12A3 protein (791-952AA) before application to samples. Specific signal should be significantly reduced.
Peptide competition assays: Compare staining patterns with and without immunizing peptide competition.
Genetic validation: Test the antibody in SLC12A3 knockout/knockdown models or cells.
Validate across multiple detection methods: Compare results across Western blot, immunohistochemistry, and ELISA.
Epitope mapping: The antibody targets amino acids 791-952 of human SLC12A3 , which should be evaluated for sequence similarity to other SLC family transporters, particularly SLC12A1 and SLC12A2 which share structural features.
Include biological validation: Verify that detection patterns match known biological distribution of SLC12A3, primarily in distal convoluted tubules .
Since this antibody is reported to be reactive with human samples , cross-species validation should be performed cautiously if attempting to use it in non-human models.
