- Immunogen/epitope region: Extracellular, C-terminus..
- Homology note: Rat - identical Human - 14 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.

These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
Solute carrier family 3 member 2 (SLC3A2), also known as 4F2 cell-surface antigen heavy chain (4F2HC) and CD98 antigen heavy chain (CD98hc), is a type II membrane protein belonging to the SLC3A/CD98 transporter family that plays a role in various physiological processes including amino acid transport, cell differentiation, migration, and proliferation.1,2,4SLC3A2 is a type II glycosylated protein composed of an extracellular domain, a transmembrane domain, and a cytoplasmic domain. SLC3A2 forms obligatory heterodimeric complexes with six members of the L-type amino acid transporters (LATs) SLC7A5-11, and SLC7A13.1The heteromeric complex between SLC3A2 and SLC7A5 (also known as LAT1) is one of the best characterized. SLC7A5 is responsible for the transport of large neutral amino acids, including leucine, across the cell membrane.
Research relevance and current trends
- Profiling immune-marker expression across cell subsets with single-cell or flow-based readouts.
- Connecting receptor/ligand levels to activation state and cytokine programs.
- Applying genetic perturbation or orthogonal assays to support specificity and 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-NT192.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
