Anti-CD9 antigen CD9 Antibody

CD9 is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Like other tetraspanins, CD9 is a cell surface glycoproteins play a role in many cellular processes including differentiation, adhesion, and signal transduction (1) . CD9 expression plays a critical role in the suppression of cancer cell motility and metastasis. In one study, the knockdown of CD9 expression suppressed the metastatic capacity of human breast cancer cells (2), while other results have shown the opposite effect, suggesting that different proteins associated with CD9 account for its abilities to promote or suppress metastasis (3) .

Involved in platelet activation and aggregation. Regulates paranodal junction formation. Involved in cell adhesion, cell motility and tumor metastasis. Required for sperm-egg fusion.

CD9 antibody can be stored at 4°C for three months and -20°C, stable for up to one year. Avoid repeated freeze-thaw cycles. Antibodies should not be exposed to prolonged high temperatures.
