Overview
Anti-PepT2/SLC15A2 (extracellular) Antibody is an antibody targeting Peptide Transporter 2, Solute Carrier Family 15 Member 2, Oligopeptide Transporter - Kidney Isoform, Kidney H+/Peptide Cotransporter Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IFC, IHC, LCI, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Peptide Transporter 2, Solute Carrier Family 15 Member 2, Oligopeptide Transporter - Kidney Isoform, Kidney H+/Peptide Cotransporter (also reported as Peptide Transporter 2, Solute Carrier Family 15 Member 2, Oligopeptide Transporter - Kidney Isoform, Kidney H+/Peptide Cotransporter).
- Immunogen/epitope region: Extracellular, 5th loop..
- Homology note: Rat - 13 out of 15 amino acid residues identical Human - 12 out of 15 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Human, Rat, Mouse.
- 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.
- Conjugate/format: Unconjugated (may affect detection channel and background).
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
Members of the proton-coupled oligopeptide transporter (POT) family are integral membrane proteins that consist of 12 transmembrane helices, having both the amino- and carboxy-terminus localized intracellularly. Four members of the POT family, called peptide transporter 1 (PEPT1, encoded by SLC15A1), peptide transporter 2 (PEPT2, encoded by SLC15A2), peptide/histidine transporter 1 (PHT1, encoded by SLC15A4) and peptide/histidine transporter 2 (PHT2, encoded by SLC15A3), have been identified in humans and other mammals1,2. They transport a wide range of di- and tripeptides and peptide-like drugs via an inwardly-directed proton gradient.
Research relevance and current trends
- Linking transporter/channel abundance to ionic homeostasis and excitability-related phenotypes.
- Studying compartment-specific localization (surface vs intracellular pools) and trafficking dynamics.
- Combining antibody readouts with functional assays for more complete interpretation.
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.
- Flow cytometry (direct/indirect): quantify target-positive populations and shifts in expression across subsets.
- 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-PT002.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
