Anti-mouse CD4 Clone GK1.5

Anti-mouse CD4 (Clone GK1.5)

The GK1.5 monoclonal antibody reacts with the mouse CD4. The CD4 antigen is a 55 kDa cell surface type I membrane glycoprotein belonging to the immunoglobulin superfamily. CD4 acts as a co-receptor which in cooperation with the T cell receptor (TCR) interacts with class II MHC molecules displayed by antigen presenting cells (APC). CD4 is expressed by the majority of thymocytes, most helper T cells, a subset of NK-T cells and weakly by dendritic cells and macrophages. CD4 plays an important role in the development of T cells and is required for mature T cells to function optimally. The GK1.5 antibody has been shown to compete with clones YTS 177 and YTS 191 for CD4 binding.

This Antibody Is Useful For:

in vivo CD4+ T cell depletion
Flow cytometry
Western blot


ALWAYS specifically formulated for in vivo use and feature:

95% purity
Ultra-low endotoxin levels
Preservative, stabilizer, and carrier protein-free


Recommended Control and Buffer:

Rat IgG2b isotype control, anti-keyhole limpet hemocyanin

The LTF-2 monoclonal antibody reacts with keyhole limpet hemocyanin (KLH). Because KLH is not expressed by mammals this antibody is ideal for use as an isotype-matched control for rat IgG2b antibodies in most in vivo and in vitro applications.
