Overview
Anti-LAT3/SLC43A1 (extracellular) Antibody is an antibody targeting Large neutral amino acids transporter small subunit 3, L-type amino acid transporter 3, Solute carrier family 43 member 1 Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Large neutral amino acids transporter small subunit 3, L-type amino acid transporter 3, Solute carrier family 43 member 1 (also reported as Large neutral amino acids transporter small subunit 3, L-type amino acid transporter 3, Solute carrier family 43 member 1).
- Immunogen/epitope region: 4th extracellular loop.
- Homology note: Rat - 13/14 amino acid residues identical; human - 10/14 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
LAT3, (L-type amino acid transporter 3) is an amino acid transporter that belongs to the system L family of membrane transporters.The system L transporter family consists of various transporter subtypes with different characteristics in substrate selectivity and transport properties. It is characterized by a Na+ independent transport and its inhibition by 2-aminobicyclo heptane-2-carboxylicacid (BCH).System L transporters are a major route to provide cells with branched-chain and aromatic amino acids. Transporters that belong to this family are present in the basolateral membrane of epithelial cells and play important roles in the absorption of amino acids through the epithelial cells of the small intestine and renal proximal tubules.
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.
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-NT193.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
