Invitrogen™ EGR2 Monoclonal Antibody (erongr2), PE, eBioscience™, Invitrogen™

Beschreibung

Description: This erongr2 monoclonal antibody recognizes mouse early growth response 2 (Egr2, Krox-20). Egr2 is a zinc finger-containing transcription factor that is important for the development of T cells and NKT cells. Egr2 is predomitly expressed in the thymus and nervous system, and it is also upregulated in T cells following TCR-crosslinking. Upregulation in all non-adherent mouse splenocytes has been observed following stimulation with phorbol 12-myristate 13-acetate (PMA) and ionomycin. Egr2 is believed to antagonize T cell activation and has also been reported to promote apoptosis. The erongr2 antibody also appears to modestly stain a subpopulation of T cells and B cells in freshly isolated spleen cells. The erongr2 monoclonal antibody is specific for Egr2 and does not crossreact to Egr3, based on immunoblot analysis. Applications Reported: This erongr2 antibody has been reported for use in flow cytometric analysis. Applications Tested: This erongr2 antibody has been tested by intracellular flow cytometric analysis of stimulated mouse splenocytes using the Foxp3/Transcription Factor Staining Buffer Set (cat. 00-5523) and protocol. This can be used at less than or equal to 0.25 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.

The EGR2 gene provides instructions for making a protein called early growth response 2, which is part of the early growth response family of proteins. These proteins bind to specific areas of DNA and help control the activity of particular genes. On the basis of this action, the proteins are referred to as transcription factors. The early growth response 2 protein activates several genes that are involved in the formation and maintenance of myelin, the fatty substance that covers and protects nerve cells. Myelin promotes the efficient transmission of nerve impulses. If myelin is lost (demyelination) or its structure is disrupted, the transmission of nerve impulses is impaired. Mutations in the EGR2 gene can cause two forms of Charcot-Marie-Tooth disease, type 1D or type 4E (sometimes called congenital hypomyelinating neuropathy) or a severe form of type 1D (sometimes called Dejerine-Sottas syndrome) that begins during infancy or early childhood.
