galectin-8 Antibody (C-8) is a mouse monoclonal IgG1 kappa light chain antibody that detects galectin-8 protein of human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). anti-galectin-8 antibody (C-8) is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. galectin-8, also known as prostate-specific membrane antigen (PCTA-1), plays a crucial role in mediating cell-cell and cell-matrix interactions, which are essential for maintaining tissue architecture and facilitating cellular communication. galectin-8 (PCTA-1) is particularly significant in prostate cancer, as expression occurs exclusively in malignant tumors, making galectin-8 a more specific biomarker compared to other prostate-specific antigens like prostate-specific antigen (PSA), which can also be elevated in benign conditions. This unique expression pattern not only aids in prostate cancer diagnosis but also provides insights into molecular mechanisms underlying tumor progression and metastasis. Using galectin-8 monoclonal antibody (C-8) in research can enhance understanding of galectin-8′s role in cancer biology and potentially contribute to targeted therapy development.

Dear Sirs, I tested anti-gal-8 Ab (SC377133) in Western blot on trophoblast cell lines (express galectin-8). Based on previous experience, I used 1/500 dilution (within recommended range). There was no specific bands, but a lot of non-spec bands.
