Overview
Anti-SLC4A4 (NBC1) (extracellular) Antibody is an antibody targeting Electrogenic sodium bicarbonate cotransporter 1, NBCe1, NBC-like protein, Na+/HCO3- cotransporter Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IC, IF, IHC, LCI, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Electrogenic sodium bicarbonate cotransporter 1, NBCe1, NBC-like protein, Na+/HCO3- cotransporter (also reported as Electrogenic sodium bicarbonate cotransporter 1, NBCe1, NBC-like protein, Na+/HCO3- cotransporter).
- Immunogen/epitope region: 2nd extracellular loop, based on the 10 transmembrane topology..
- Homology note: Rat - 13/14 amino acid residues identical; mouse - 12/14 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Rat, Mouse.
- Specificity statement (as provided): Not recommended for human samples. The antibody will recognize all known rat splice variants.
- Lot quality control (as provided): Western blot analysis.
- Peptide confirmation: Confirmed by amino acid analysis and mass spectrometry.
- Blocking peptide: Available for antigen preadsorption control where appropriate.
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
SLC4 membrane transporter proteins play important roles in kidney acid-base regulation through their transport of bicarbonate (or carbonate), Na+, Cl-, and (possibly NH4+)1. These transporters differ in their substrate (Na+, Cl-) dependence, charge transport stoichiometry, cell-type and developmental expression, functional regulation, and protein-protein interactions. In mammals, SLC4 proteins are encoded by 10 different genes that share protein sequence homology and are grouped according to their functional properties.In humans, the electrogenic sodium bicarbonate cotransporter NBCe1 is encoded by the SLC4A4 gene2.
Research relevance and current trends
- Comparing target expression across perturbations, genotypes, or treatment conditions.
- Interpreting localization shifts alongside pathway or phenotypic readouts.
- Using orthogonal controls (KO/KD, peptide competition, isotype concepts) to support conclusions.
Common research applications
- Western blot (WB): compare target abundance/size across lysates and conditions; consider isoforms/PTMs.
- Immunohistochemistry (IHC): examine spatial distribution in tissue and relate signal to cell-type composition.
- Immunofluorescence/ICC: assess subcellular localization and co-localization with markers in cells or sections.
- Live cell imaging (LCI): support extracellular-epitope detection on non-permeabilized cells when appropriate.
Interpretation typically benefits from comparing matched sample sets (e.g., treated vs control, WT vs KO/KD) and using orthogonal readouts where feasible.
Notes for experimental interpretation
- Isoforms and post-translational modifications can shift apparent molecular weight or epitope accessibility across samples.
- Cross-species signal may depend on epitope conservation; consult the provided homology note when selecting models.
- Permeabilization, fixation, and antigen retrieval can change accessibility of intracellular vs extracellular epitopes.
- Conceptual control: antigen preadsorption (blocking peptide) can help assess signal dependence on the immunogen region.
- Provided control suggestions: Negative control: BLP-NT075.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
