Description: The 4H1 monoclonal antibody reacts with the human CD116 molecule, the alpha subunit of GM-CSF receptor. The alpha subunit associates with the common beta chain (CD131) to form the high affinity receptor for GM-CSF. The GM-CSFR alpha chain is expressed by granulocytes, monocytes, endothelial cells, fibroblasts and some tumor cells.
Applications Reported: 4H1 has been reported for use in flow cytometric analysis.
Applications Tested: This 4H1 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (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.
Excitation: 488 nm; Emission: 520 nm; Laser: Blue Laser.
Filtration: 0.2 µm post-manufacturing filtered.
The human IL-3, IL-5 and GM-CSF receptors are each composed of both unique a subunits and a common beta subunit. The a subunits are low affinity ligand binding proteins while the beta subunits do not themselves bind ligand, but are required for high affinity binding by the a subunits. In contrast, the mouse IL-3 receptor has two distinct beta subunits, one that functions only in IL-3 mediated cell signaling and a second that is shared with IL-5 and GM-CSF. The murine beta-subunits are 91% homologous at the amino acid level but only 56% homologous to the human beta subunit. Although neither the murine nor the human beta subunit contains tyrosine kinase domains, both activate tyrosine phosphorylation mediated signaling pathways.
