CD123 Monoclonal Antibody (5B11), FITC, eBioscience™, Invitrogen™

Description

• Description: The 5B11 monoclonal antibody reacts with mouse CD123, the alpha chain of the IL-3 receptor
• This 60-70 kDa transmembrane protein binds to IL-3 with low affinity by itself and when associated with either CD131 (common beta chain) or AIC2A (IL-3beta) binds IL-3 with high affinity
• CD123 does not transduce any intracellular signals upon binding IL-3 and requires the beta chain for this function
• Applications Reported: This 5B11 antibody has been reported for use in flow cytometric analysis
• Applications Tested: This 5B11 antibody has been tested by flow cytometric analysis of mouse bone marrow cell suspension
• 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
• Excitation: 488 nm; Emission: 520 nm; Laser: Blue Laser
• Filtration: 0.2 μm post-manufacturing filtered
• IL-3Ra (Interleukin-3 receptor subunit alpha) belongs to the type I cytokine receptor family and is a heterodimer with a unique alpha chain paired with the common beta (beta c or CDw131) subunit
• IL-3Ra is responsible for the transmission of signal of Interleukin-3
• IL-3Ra and IL-3Rb chain heterodimerization is induced by Interleukin-3, which is required for receptor activation but not high affinity binding
• IL-3Ra is also reported that IL-3Ra subunits are overexpressed on acute myeloid leukemia (AML) blasts compared with normal hematopoietic cells and are thus potential targets for novel therapeutic agents.
