Size: 20ul / 100ul The CD9 (84142-2-RR) by Proteintech is a Recombinant antibody targeting CD9 in WB, IF/ICC, ELISA applications with reactivity to human samples 84142-2-RR targets CD9 in WB, IF/ICC, ELISA applications and shows reactivity with human samples. Tested Applications Positive WB detected in: HeLa cells, L02 cells, human placenta tissue Positive IF/ICC detected in: MCF-7 cells Recommended dilution Western Blot (WB): WB : 1:5000-1:50000 Immunofluorescence (IF)/ICC: IF/ICC : 1:250-1:1000 Background Information The cell-surface molecule CD9, a member of the transmembrane-4 superfamily, interacts with the integrin family and other membrane proteins and is postulated to participate in cell migration and adhesion. Expression of CD9 enhances membrane fusion between muscle cells and promotes viral infection in some cells (PMID:10459022). It is often used as a mesenchymal stem cell marker (PMID:18005405). The CD9 antigen appears to be a 227-amino acid molecule with four hydrophobic domains and one N-glycosylation site (PMID: 1840589). This antibody detects bands of 23-30 kDa, which may be due to the difference in glycosylations (PMID: 8701996).
