  • 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.

Thank you for your enquiry.

I have checked these product numbers. I am sorry to confirm that ab4098 is discontinued and apologize for the inconvenience.

ab4098 is an antibody for detection of Nucleophosmin. However, ab101530 is an antibody for detection of CD4, which is a different protein. I would appreciate if you could you confirm these are the correctcatalog numbers so I can provide you withright information?

Please let me know which application and species the customer will be using, and for detection of which protein, and I will be pleased to find a suitable product for them.

Many thanks for your cooperation. I look forward to hearing from you.

Thank you very much for your phone call.

The best antibodies we can recommend are as follows. Please note that the recommendations are based on immunogen sequence only we currently do not hold any rabbit specific data.

Anti CD3 : ab16669; I can provide Abreview image discount code and will also provide Abpromise guarantee on use for this ab.

Anti FOXP3: ab20034, ab22510 are best antibodies we can offer. Eligible for new species Abreview discount code however not eligible for refund in case it does not work.

Anti CD4: ab61131, ab101530 and ab108329, are the best antibodies we can offer. Eligible for new species Abreview discount code however not eligible for refund in case it does not work.

anti CD8: ab108343, ab123630 and ab86733, are the best antibodies we can offer. Eligible for new species Abreview discount code however not eligible for refund in case it does not work.

Anti CD1A : ab76531, ab108309 and ab123133 are the best antibodies we can offer. Eligible for new species Abreview discount code however not eligible for refund in case it does not work.

Please also note that most of these antibodies are raised in Rabbit so there will be high back ground staining. Our recommendations to reduce the back ground staining are

- Use preadsorbed anti body e.g. ab7132, ab7083, ab

- Use (Fab)2 fragments antibodies e.g. ab6112, ab102296

- Incubate sections with affinity pure Fab fragment anti rabbit antibody before applying primary antibody

Could you please select the antibodies you are interested in, I will then be happy in creating a discount code for each one of these.

I will look forward to hearing from you soon.
