Primary antibody notes ab34110 has been shown to block MHCII dependent T cell responses in vivo and in vitro. In the dog CD4 is expressed by neutrophils as well as by lymphocytes subsets.
Clone number YKIX302.9
Abpromise guarantee covers the use of
in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
ab18450-Rat monoclonal IgG2a, is suitable for use as an isotype control with this antibody.
Use at an assay dependent concentration.
Function Accessory protein for MHC class-II antigen/T-cell receptor interaction. May regulate T-cell activation. Induces the aggregation of lipid rafts.
Sequence similarities Contains 3 Ig-like C2-type (immunoglobulin-like) domains. Contains 1 Ig-like V-type (immunoglobulin-like) domain.
Post-translational modifications Palmitoylation and association with LCK contribute to the enrichment of CD4 in lipid rafts.
Cellular localization Cell membrane. Localizes to lipid rafts. Removed from plasma membrane by HIV-1 Nef protein that increases clathrin-dependent endocytosis of this antigen to target it to lysosomal degradation. Cell surface expression is also down-modulated by HIV-1 Envelope polyprotein gp160 that interacts with, and sequesters CD4 in the endoplasmic reticulum.
