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: The 4H1 antibody has been tested by flow cytometric analysis of normal human peripheral blood cells. 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.
Purity: Greater than 90%, as determined by SDS-PAGE.
Aggregation: Less than 10%, as determined by HPLC.
Filtration: 0.2 µm post-manufacturing filtered.
The protein encoded by this gene is the alpha subunit of the heterodimeric receptor for colony stimulating factor 2, a cytokine which controls the production, differentiation, and function of granulocytes and macrophages. The encoded protein is a member of the cytokine family of receptors. This gene is found in the pseudoautosomal region (PAR) of the X and Y chromosomes. Multiple transcript variants encoding different isoforms have been found for this gene, with some of the isoforms being membrane-bound and others being soluble.
