Overview
Anti-Tetraspanin 7 (extracellular) Antibody is an antibody targeting TSPAN7, Transmembrane 4 Superfamily Member 2, TM4SF2, T-Cell Acute Lymphoblastic Leukemia-Associated Antigen 1, TALLA-1, Cell Surface Glycoprotein A15, A15, CD231. 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: TSPAN7, Transmembrane 4 Superfamily Member 2, TM4SF2, T-Cell Acute Lymphoblastic Leukemia-Associated Antigen 1, TALLA-1, Cell Surface Glycoprotein A15, A15, CD231. (also reported as TSPAN7, Transmembrane 4 Superfamily Member 2, TM4SF2, T-Cell Acute Lymphoblastic Leukemia-Associated Antigen 1, TALLA-1, Cell Surface Glycoprotein A15, A15, CD231.).
- Immunogen/epitope region: Extracellular, 2nd loop..
- Homology note: Mouse - 15 out of 16 amino acid residues identical; rat - 14 out of 16 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
Tetraspanins (Tspans) are a family of four-span transmembrane proteins, known as plasma membrane "master organizers." They form Tspan-enriched microdomains (TEMs or TERMs) through lateral association with one another and other membrane proteins.1Tetraspanins are characterized by four transmembrane domains, two extracellular loops: one small extracellular loop (SEL or EC1) and one larger extracellular loop (LEL or EC2), a short intracellular loop, and two short intracellular tails.1Teatraspanin 7 (TSPAN7) is highly expressed in the brain and was first described as a candidate gene for X-linked intellectual disability, probably through the modulation of surface expression of AMPA and dopamine receptors.2Tetraspanin 7 also has a key role in controlling pancreatic β-cell Ca2+ handling and defining the set-point of insulin secretion through modulation of L-type Cav1.2 and Cav1.3 channels. Furthermore, it has been identified as a target for autoantibodies in Type I diabetes. 3In addition, Tetraspanin 7 is involved in the regulation of HIV virus entry into dendritic cells and several types of cancer progression.
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-NR187.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
