CD104 (Integrin beta 4) Monoclonal Antibody (439-9B), eFluor™ 660, eBioscience™, Invitrogen™

Description

Description: The monoclonal antibody 439-9B recognizes human CD104, also known as integrin beta 4. CD104 is a 202 kDa subunit that associates with integrin alpha 6 (CD49f), thereby forming the laminin receptor. Multiple splice variants have been identified. Expression is found on epithelial cells and tumor cells and has been shown to be involved in cell-matrix and cell-cell interactions. The role of CD104 in tumorigenicity is well established. The monoclonal antibody 439-9B has been reported to have no effect on adhesion of human colon adenocarcinoma cells. Moreover, this antibody crossreacts to bovine. Applications Reported: This 439-9B antibody has been reported for use in flow cytometric analysis. Applications Tested: This 439-9B antibody has been tested by flow cytometric analysis of A549 cell line. This can be used at less than or equal to 1 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. eFluor™ 660 is a replacement for Alexa Fluor™ 647. eFluor™ 660 emits at 659 nm and is excited with the red laser (633 nm). Please make sure that your instrument is capable of detecting this fluorochome.
