Our Abpromise guarantee covers the use of ab33775 in the following tested applications.

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

Application Abreviews Notes
ICC Use at an assay dependent concentration.
Flow Cyt 1/10 - 1/50.

Use 10µl of the suggested working dilution to label 106 cells in 100µl.




ab170191 - Mouse monoclonal IgG2a, is suitable for use as an isotype control with this antibody.


IHC-Fr 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

    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.

Customer reviews and Q&As


Thank you for contacting us. ab31630, can be used in IHC-P ab8536, can be used in IHC-P ab65865; IHC-P is yet not tested we are unable to confirm it. Can we suggest alternatives as ab34364, ab87951 and ab101500? ab33775; IHC-P is not a tested application we are unable to confirm its use. We suggest using alternative as ab846, ab51312 ab33854; IHC-P again is not a tested application for this ab. We can suggest using ab9496, ab59754 In case you are interested in buying ab65865, ab33775 and ab33854 only I can then offer you three Abreview discount codes which will give you next three antibodies free of charge. Please be advised that in some cases heat damages the antigenic epitope we therefore always recommend our customers optimizing the heat mediated antigen retrieval step. Let me know if you are interested in my offer; I will then send you the discount codes. The alternatives are recommended based on their use in IHC-P so I would also suggest carefully checking the datasheet particularly immunogen and species in case you plan to use these antibodies. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
