Our Abpromise guarantee covers the use of ab18282 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|Flow Cyt||Use at an assay dependent concentration.
Use 5-20µl for 100µl whole human blood cells.
ab91357 - Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.
FunctionAccessory protein for MHC class-II antigen/T-cell receptor interaction. May regulate T-cell activation. Induces the aggregation of lipid rafts.
Sequence similaritiesContains 3 Ig-like C2-type (immunoglobulin-like) domains.
Contains 1 Ig-like V-type (immunoglobulin-like) domain.
modificationsPalmitoylation and association with LCK contribute to the enrichment of CD4 in lipid rafts.
Cellular localizationCell 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.
