Flow Cytometry Product Notes: Test Sizes: To accommodate multicolor flow cytometry, eBioscience is in the process of reducing test size volumes from 20 µl to 5 µl. Please check your antibody vial for the recommended test size. Fluorochrome Replacements: eBioscience is in the process of replacing all Pacific Blue® and APC-Alexa Fluor® 750 conjugated products with eFluor™ 450 and APC-eFluor™ 780 conjugated products, respectively.
Description
This B73.1 monoclonal antibody reacts with human CD16, a member of the Fc receptor family also known as FcγRIIIa and FcγRIIIb. This 50-65 kDa receptor is expressed on natural killer cells, neutrophils, monocytes, and macrophages. Crosslinking of CD16 in natural killer cells and monocytes results in activation of the MAPK and PI3K signaling pathways, thus regulating the production of TNFα, IL-6, and IL-1β.
This monoclonal antibody has been shown to block Fc receptor functions.
Applications Reported
For research use only, not for diagnostic or therapeutic use. This B73.1 (B73.1.1) antibody has been reported for use in flow cytometric analysis.
Applications Tested
This B73.1 (B73.1.1) antibody has been pre-titrated and tested by flow cytometric analysis of normal peripheral blood cells. This can be used at 5 μl (0.5 μg) per million cells in a 100 μl total staining volume.
