Description

Mouse Monoclonal Antibody

Description: This 7G3 monoclonal antibody reacts with human and non-human primate 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 CD131 (the common beta chain) binds IL-3 with high affinity. CD123 is expressed by myeloid precursors, macrophages, dendritic cells, mast cells, basophils, and megakaryocytes. In addition, this molecule can be detected on CD34+CD38- hematopoietic stem cells and acute myeloid leukemic (AML) cells. The 7G3 antibody has been demonstrated to inhibit IL-3-mediated cell proliferation and homing of AML leukemic stem cells. Crossblocking studies suggest that 7G3 recognizes a different epitope from 6H6. The 7G3 antibody has been reported to crossreact to chimpanzee, cynomologous monkey, olive baboon, pigtailed macaque, rhesus macaque, and sooty mangabey. Applications Reported: This 7G3 antibody has been reported for use in flow cytometric analysis. Applications Tested: This 7G3 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 μL (0.5 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. eFluor® 450 is an alternative to Pacific Blue®. eFluor® 450 emits at 445 nm and is excited with the Violet las...

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.

Frequently Asked Questions (FAQs)

I am unable to analyze my cells stained with eFluor Organic Dyes today. What options do I have?

Our options will depend on the samples you are analyzing.

If cell viability is not critical, you can store your stained samples at 4 degrees C or on ice overnight in the dark and analyze the following day.

For samples stained with eFluor organic fluorochromes, we recommend that cells be suspended in 100 uL of Flow Cytometry Staining Buffer (Cat. No. 00-4222) and 100 uL of eBioscience IC Fixation Buffer (Cat. No. 00-8222); samples can be incubated for up to 3 days at 4 degrees C in the dark. Alternatively, the 1-step Fix/Lyse Solution (Cat. No. 00-5333) can be used. This is a great option when working with whole blood but also works for other cell types.

What is the difference between eFluor Organic Dyes and eVolve Qdots?

The eFluor Organic Dyes (eFluor 450, APC-eFluor 780, PerCP-eFluor 710, eFluor 710) are conventional fluorochromes. In contrast, the eVolve line of products are Quantum dots.

Are the eFluor Organic Dyes photo-labile?

As with other fluorochromes, we recommend minimal exposure to light to maintain optimal signal.
