  • 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.
  • Cellular localization

Vielen Dank für Ihre Anfrage.

Leider muss ich Ihnen mitteilen, dass dies nicht zu unseren Standartmethoden gehört, wenn wir einen Antikörper entwickeln und charakterisieren.

Was Sie allerdings machen könnten, wenn Sie diesen Antikörper bereits erworben haben um das ungefähre Gewicht zu ermitteln, wäre einen WB unter Nicht-reduzierenden Bedingungen, also ohne beta-Mercapthoethanol oder DTT Zugabe, mit dem Antikörper als Probe laufen zu lassen: Der Antikörper sollte sich (zum größten Teil) nicht in die leichte und schwere Kette aufspalten, und die Biotin-Konkugationsollte ebenfalls erhalten bleiben.

Ich hoffe, dies hilft Ihnen trotzdem weiter. Bitte zögern Sie nicht, sich wieder bei uns zu melden, falls Sie weitere Fragen haben.

Thank you for your enquiry and your interest in our products.
This antibody has not been tested against the HXB2 or JRFL strains yet. However, given the polyclonal nature of the antibody, there is a good chance it would react to these strains but currently we do not have any empirical data to support this.
If you need any further assistance in the future, please do not hesitate to contact me.

Thank you for contacting us. This product is raised from purified native gp120 from strain IIIB. We have not sequenced the native protein used to raise this antibody. We have searched, and unfortunately, the gp120 sequence has not been submitted for strain IIIB. Linked below is the entire genome for strain IIIB. gp120 is encoded by the env gene, but without knowing for sure which promoter and reading frame is used for this strain we cannot send specifically the gp120 sequence. http://www.hiv.lanl.gov/components/sequence/HIV/asearch/query_one.comp?se_id=18154 I hope this information is helpful to you.

Thank you for your reply. To reduce the non-specific binding of your secondary antibody, you could: - Change your blocking agent, to either 5% non fat dried milk or 5% BSA. - Lower the concentration of the secondary antibody that you are using. - Add between 0.1-0.55 Tween20 to the secondary antibody solution. - Increase the number of wash steps that you are currently using. Hopefully some of the protocol tips would help alleviate the problem. If you continue to see non-specific binding of the secondary antibody, then if you purchased it from Abcam, I would be happy to send a replacement. If you purchased it from another company, then I would suggest contacting them and asking them for a replacement antibody. Please let me know if there is anything else I can help you with.

Thank you for contacting Abcam. I just want to make sure that I understand your negative control correctly; for your negative control, you added the secondary antibody only (no primary antibody) and that is the lane labeled 'gp120 negative'. Is that correct? If so, then I believe that the issue is that your secondary antibody is non-specifically binding to the other bands, as you are seeing the same banding pattern, in the secondary only lane (no ab53937 present). If I am reading your image incorrectly, I do apologize. Would you be able to send me more information on the protocol you used, including the samples that were loaded onto the gel. By sending this extra information, I will hopefully be able to help you more. I look forward to your reply.

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.
