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.

  • Cellular localization

    Envelope surface glycoprotein.

  • Alternative names

    • Glycoprotein 120 antibody

Question

I am looking for about 5-mg of label goat anti-HIV 1 gp120 antibodies with TEXAS RED or HIV-1 gp120 with texas red. Could you also please inform me of the other types of labels you would be able to put onto goat anti-HIV gp120, for example; Phycoerythrin or PECy 5.5.
Kind regards,

Answer

Laboratory has finally confirmed that these products cannot be supplied with Texas Red conjugation so I am sorry we are unable to honour your request this time.

We however have conjugation kits available, e.g.

https://www.abcam.com/EasyLink-Texas-Red-Conjugation-Kit-3-x-100µg-TR-ab102924.html

Question

Hello,

We would like to immobilize Anti-HIV1 gp120 onto a surface to show efficacy in capturing HIV protein.

Our current thought is to:
1. Immobilize Anti-HIV1 gp120 antibody (Product # ab21179)
2.Capture HIV1 gp120 + gp41 protein (Product #ab68127)
3. Use the secondary protein, Anti-HIV1 gp41 (Product # ab68622) conjugated to HRP to measure and quantify the amount of captured protein.

Can you confirm that the three products (ab21179, ab68127, and ab68622) will interact as predicted?

Answer

Thank you for contacting us. Theoretically your outline makes sense. However, we have not tested the products this way and cannot guarantee that the binding sites of the antibodies will not interfere with each other. I hope this is helpful. Please le me know if I can be of further assistance.

Question

Thank you for answer and help. I will try again with more normal brain samples and with reduction of protein. I loaded 20-30 ug of brain lysate and 1.5 ul from ur recombinant protein as positive control. I will repeat again and let you know maybe we can get one more gp120 gt ab in exchange of rabbit one or I will look for any other product that we may need from Abcam. I will keep you updated. The strong band that we got with GP120 looks like specific but the problem is it appear in normal brain too.

Thanks a lot,

Answer

Thank you very much for your reply.

Please keep me updated about the results after making those changes. I'll be happy to send another GP120 antibody or any other antibody that you might need.

I look forward to hearing from you. If there is anything else we can do for you, please let me know and I'll be happy to help.

Question


I have tested the protein that you sent me and I attached the results.
Both abs that I have from Abcam binds the recombinant protein GP120 ( as two bands) but it looks like for the brain lysates rb GP120 is non specific ( got same pattern small intesity bands in cell lysates).
Gt GP120 it recognizes a band around 60-70 kDa ( that I thought is unglycosilated GP120 )but the problem is is binds also in the normal brain lysates ( any guess or suggestions?)
I attached the figures and if I would have a scientific input on this I will really appreciated. Regarding the antibodies, could we try more if you have any samples available?
I have use as negative control SKN Sh cell line and normal brain lysate. All dilutions were 1:1000.
Thank you,

Answer

Thank you very much for your email and for keeping me updated about the results with the recombinant protein.

I am sorry to see that the results are still not as expected. From your images, it seems that the bands in both of the brain lysates are non-specific, since the same bands are appearing in infected and non-infected samples. The banding pattern in the brain lysates is also different using ab21179 and ab106578, which also tells me this is non-specific binding. Has the GP120 titer been measured in the infected brain sample? My only explanation is that the level of the antigen may be below the detection limit of the antibody, but I'm not sure that is the case.

The GP120 protein ab69717 might have some degradation products or impurities at lower molecular weights as well, which appear as the bands around 40 and 55 kDa. How much of this protein was loaded per lane? We suggest 0.1-1 ug/lane, and loading less protein should decrease the visibility of these bands.

We don't have any samples of our antibodies, but I'd be happy to send you a replacement antibody if it will be helpful for you. Which antibody would you like to try?

I look forward to hearing from you. If there is anything else that we can do for you, please let me know and I'll be happy to help.

Question

Just as a reminder could you please check is this GO120 recombinant protein is good for WB and how much I should load to get the signal?

Thank you.

Answer

Thank you very much for your replies yesterday.

I'm sending a free of charge vial of ab69717 on the order *** which should arrive tomorrow. This protein has been tested in Western blot using 0.1-1 ug per lane. Please keep me updated about the results with the antibodies in WB against this protein.

I look forward to hearing from you. If there is anything else that we can do for you, please let me know and I'll be happy to help.

Question

Thank you for your answer. As we talked a few days ago about GP120 ab, I may need to run some GP120 recombinant protein as control for my WB.

I just figures out that I have a very little amount in the lab. I was wondering if you could help me with some that I can use it to validate the GP120 ab.

Thank you so much,

Answer

Thank you very much for your reply.

I can send a vial of one of our GP120 proteins to use as a positive control. Would ab69717 work for you?

https://www.abcam.com/HIV1-gp120-protein-ab69717.html

Please confirm this and I will send a vial to you promptly. If there is anything else that we can do for you, please don't hesitate to ask.

Question

I have used Ab53837 successfully for Western blots and am interested in a non-conjugated version of this Ab. I see at least a couple goat polyclonal anti-gp120 antisera but I can't tell if there is a product that is identical to 53837 without the HRP. Can you help me with this please? Thanks in advance.

Answer

Unfortunately, it looks like we do not have the unconjugated form of ab53837 Anti-HIV1 antibody (HRP) in our catalogue.
However, we have one antibody which may interest you:

https://www.abcam.com/index.html?datasheet=21179 (or use the following: https://www.abcam.com/index.html?datasheet=21179).

It's a goat antibody as well, and has a good customer review in WB as well as four WB references.

Question

Dear Sir or Madame,   I am looking for a HIV gp120 specific antibody and came across your product list. I would like to use it in an affinity column (using Dynabeads, Invitrogen) to purify gp120 and was wondering if you can recommend a specific antibody of your range for this purpose.     Thanks a lot for your help.   Kind regards,

Read More
Answer

Thank you for your enquiry and your interest in our products. I have conducted a search for you on our website and found several antibodies against HIV gp120. Although, none of them have been specifically listed for use in affinity purification (AP); two of them (ab21179 and ab36921) are suitable for conjugation experiments. I would suggest taking a look at the on-line product datasheets to see which one suits your need. ab21179: https://www.abcam.com/HIV1-gp120-antibody-ab21179.html ab36921: https://www.abcam.com/HIV1-antibody-ab36921.html I hope this helps and if I can assist further, please do not hesitate to contact me.
