Description

Tetraspanin 8 (TSPAN8) has emerged as a compelling target in cancer research, where its role in tumor progression, metastasis, and exosome-mediated intercellular communication continues to attract significant attention. As a member of the tetraspanin superfamily, TSPAN8 organizes membrane microdomains that facilitate integrin signaling and cell-cell interactions, making it both a potential biomarker and a functional player in malignant transformation across multiple cancer types.

This recombinant monoclonal antibody, clone 6D4, offers researchers the reproducibility essential for longitudinal studies and multi-site collaborations. Because the antibody sequence is defined and production occurs in controlled recombinant systems, you can expect consistent performance across lots, eliminating the variability that often complicates experiments using traditional hybridoma-derived reagents. The human IgG1 format provides predictable binding characteristics and compatibility with standard secondary detection systems.

Validation through flow cytometry demonstrates clear specificity for human TSPAN8. Testing on transfected MC38 cells expressing human TSPAN8 showed distinct positive staining compared to untransfected controls, confirming target recognition. Additional flow cytometry analysis using HT29 cells, a human colorectal adenocarcinoma line that endogenously expresses TSPAN8, further supports the antibody's utility for detecting native protein on human cancer cells. Recommended working dilutions range from 1:50 to 1:200 for flow cytometry applications, providing flexibility to optimize signal-to-background ratios in your specific experimental system.

Whether investigating TSPAN8's contribution to tumor-associated antigen profiles, examining its involvement in signal transduction pathways, or characterizing cell surface marker expression patterns, this antibody delivers the specificity and batch consistency that rigorous cancer research demands.

Target Background

Gene References into Functions
  1. TSPAN8 mediated Wnt/beta-catenin pathway through binding to NOTCH2. The role of TSPAN8 in the drug resistance of gastric cancer. PMID: 29345284
  2. these data point to a crucial role of Co-029 in the modulation of colon cancer cell motility which could be related to the protumoral effect reported for this tetraspanin. Among surface molecules able to mediate Co-029 function, E-cadherin, EGFR and CD44 appear as likely candidates. PMID: 28418857
  3. Single nucleotide polymorphism in TSPAN8 gene is associated with pathogenesis of bipolar disorder. PMID: 28777493
  4. Tetraspanin-8 has a role in promoting hepatocellular carcinoma metastasis by increasing ADAM12m expression PMID: 27270327
  5. LCMR1 modulation was sufficient to positively regulate endogenous Tspan8 expression, with concomitant in vitro phenotypic changes such as loss of melanoma cell-matrix adherence and increase in invasion, and Tspan8 expression promoted tumourigenicity in vivo. PMID: 27375018
  6. Data indicate a regulatory role for tetraspanin 8 (Tspan8) in melanoma progression by modulating cell-matrix interactions through beta1 integrin - integrin-linked kinase (ILK) axis and establish Tspan8 as a negative regulator of ILK activity. PMID: 28188308
  7. TSPAN8 might be important for the orchestration of meprin beta at the cell surface with impact on certain proteolytic processes PMID: 27180358
  8. Knocking down TSPAN8 in AEG-1-overexpressing human hepatocellular carcinoma (HCC) cells markedly inhibited invasion and migration without affecting proliferation. TSPAN8 knockdown profoundly abrogated AEG-1-induced primary tumor and intrahepatic metastasis in an orthopic xenograft model in athymic nude mice PMID: 27339400
  9. Knockdown and knockout models revealed that CD151 and Tspan8 act as molecular facilitators in wound healing, angiogenesis and tumor progression. [review] PMID: 28408484
  10. Results provide evidence that TSPAN8 may contribute to the pathogenesis of lung cancer by promoting cell viability and proliferation. PMID: 27996312
  11. TSPAN8 is involved in tumor progression and is an independent prognostic classifier in patients with gastric cancer. PMID: 25711980
  12. This novel nuclear localization of TM4SF3 depends on androgen-induced nuclear localization of androgen receptor (AR) in both androgen-dependent and androgen-independent prostate cancer cell lines PMID: 26649804
  13. Our data suggest that TSPAN8-LEL may play an important role in mCRC cell invasion, and that the antibody we have developed could be a useful tool for inhibiting the invasion of TSPAN8-expressing mCRCs. PMID: 26562525
  14. Based on nasopharyngeal TSPAN8 gene expression in readily available Nasopharyngeal aspirate samples , we can discriminate between severity of disease in Respiratory syncytial virus infected infants. PMID: 25261323
  15. Tspn8 was over-expressed in multiple clinical malignant glioma tissues, and its expression level correlated with the grade of tumors. PMID: 25680464
  16. CO-029 functions as a regulator of both cell-matrix and cell-cell adhesion. During colon cancer progression, CO-029 promotes cancer cell movement by deregulating cell adhesions. PMID: 22679508
  17. PMA-induced Tspan8-internalization promotes cell migration, but reduces matrix and cell adhesion. PMID: 20937409
  18. High TSPAN8 is associated with melanoma invasiveness. PMID: 21081927
  19. claudin-7-associated EpCAM is recruited into (tetraspanin-enriched membrane microdomains) and forms a complex with CO-029 and CD44v6 that facilitates metastasis formation PMID: 17579117
  20. overexpression of TM4SF3 in esophageal cancer conferred advantage to the invasion and metastasis of this destructive disease PMID: 18365756
