Specifications

Our Abpromise guarantee covers the use of ab221226 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • Applications

    SDS-PAGE

  • Form

    Lyophilised
  • Concentration information loading...

Preparation and Storage

  • Stability and Storage

    Shipped at 4°C. Store at -80°C. Avoid freeze / thaw cycle.

    pH: 7.40
    Constituents: 5% Trehalose, PBS

    Lyophilized from 0.22 µm filtered solution.
    5-10% trehalose is commonly used for freeze drying, and after reconstitution, the trehalose is mostly about 3-5%

  • Reconstitution
    It is recommended to reconstitute the lyophilized protein in sterile deionized water to a final concentration of 1 mg/mL. Solubilize for 30 to 60 minutes at room temperature with occasional gentle mixing. Carrier protein (0.1% HSA or BSA) is strongly recommended for further dilution and long term storage.

  • 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.
