Scientific Data Images for Human TSPAN8 Antibody

Detection of Human TSPAN8 antibody by Western Blot.

Detection of Human TSPAN8 by Western Blot.

Western blot shows lysates of COLO 205 human colorectal adenocarcinoma cell line and HT-29 human colon adenocarcinoma cell line. PVDF membrane was probed with 2 µg/mL of Rat Anti-Human TSPAN8 Monoclonal Antibody (Catalog # MAB4734) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (HAF005). A specific band was detected for TSPAN8 at approximately 35 kDa (as indicated). This experiment was conducted under non-reducing conditions and using Immunoblot Buffer Group 1.
Detection of TSPAN8 antibody in HT‑29 Human Cell Line antibody by Flow Cytometry.

Detection of TSPAN8 in HT‑29 Human Cell Line by Flow Cytometry.

HT-29 human colon adenocarcinoma cell line was stained with Rat Anti-Human TSPAN8 Monoclonal Antibody (Catalog # MAB4734, filled histogram) or isotype control antibody (MAB0061, open histogram), followed by Allophycocyanin-conjugated Anti-Rat IgG F(ab')2Secondary Antibody (Catalog # F0113).

TSPAN8 antibody in HT-29 Human Cell Line by Immunocytochemistry (ICC).

TSPAN8 in HT‑29 Human Cell Line.

TSPAN8 was detected in immersion fixed HT-29 human colon adenocarcinoma cell line using Rat Anti-Human TSPAN8 Monoclonal Antibody (Catalog # MAB4734) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; NL013) and counterstained with DAPI (blue).

Detection of TSPAN8 in HT‑29 Human Colon Adenocarcinoma Cell Line (Positive) and Daudi Human Burkitt's Lymphoma Cell Line (Negative) Cells.

TSPAN8 was detected in immersion fixed HT‑29 Human Colon Adenocarcinoma Cell Line (Positive) and Daudi Human Burkitt's Lymphoma Cell Line (Negative) Cells using Rat Anti-Human TSPAN8 Monoclonal Antibody (Catalog # MAB4734) at 3 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cell surface. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: TSPAN8

Tetraspanin-8 (TSPAN8), also known as TM4SF3 and human tumor-associated antigen CO-0029, is a member of the transmembrane 4 superfamily. It is a cell surface 27‑34 kDa glycoprotein with 4 transmembrane segments, and a large extracellular loop (LEL) domain from amino acids (aa) 106‑206. Both the N- and C-termini are intracellular. TSPAN8 is expressed by multiple tumor types as well as smooth and skeletal muscle cells, endothelial cells, hematopoietic progenitor cells and non-keratinized squamous epithelium. As with other TSPAN family molecules, TSPAN8 acts as an organizer of microdomains in membranes. Molecules that may be found in these domains include CD151 (another TSPAN family member), beta 1 Integrins, Integrin alpha 4 beta 6, EpCAM, and CD13. TSPAN8 would appear to remove Integrins from the cell surface, facilitating cell motility which, in the case of tumor cells, results in metastasis. TSPAN8 shares 53% aa sequence identity with both mouse and rat TSPAN8.
