  • Target

    • Relevance

      HIV1 is equipped with the envelope gp160 glycoprotein for interaction with Langerhans cells (LCs) and dendritic cells (DCs), the members of the innate immune system, which confront the virus at the portal of virus entry in the human body. These cells are equipped with receptors by which they bind and endocytose the virus. The gp120 glycoprotein is used for binding to CD4 receptor and CCR5 co-receptor of T helper 2 (Th2) cells, and is able to induce FcepsilonRI(+) hematopoietic cells to produce IL4, which inactivates the host adaptive immune response.

    Thank you for your inquiry.

    I can confirm that the immunogen for ab20008is purified native gp120 from HIV strain IIIB.

    Since it is a polyclonal antibody we do not know where exactly it bind in the protein.

    We have one mouse monoclonal antibody where the immunogen is is now and a short peptide sequence: ab24745, WQEVGKAMYAPPISGQIRCSSN, corresponding to amino acids 427-448 of Human HIV type I (BH8 isolate) gp120

    Thank you for your enquiry. These 4 products (ab21179, ab20105, ab20262, ab20008) were produced from the same goat antiserum. Catalog ab21179 is the purified antibody. The purified antibody is then labeled to produce the other catalog numbers: Biotin (ab20105), FITC (ab20262), HRP (ab20008). Meanwhile, ab53840 and ab53937 originate from the same goat antisera. Unfortunately, we do not have the unconjugated version of these antibodies in our catalog but I may check with the originator if it is available. Please let me know if you would like to proceed with an order.

    Thank you for your enquiry. I have been in touch with the source of these HIV gp120 and gp41 antibodies and I have determine that unfortunately none of them have been tested against the HIV strain YU2. I can tell you that ab18633 is predicted, based on broad reactivity to react with HIV strain YU2. I am sorry that I cannot be of more assistance on this occasion.
