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

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

Can you tell me the exact immunogen sequence of this product, HIV1 gp120 antibody (4641) please? If the information is proprietary, then could you please inform if the product can detect HIV-1 gp120 in JRFL lysates, and NL4-3 lysates? Ideally, by knowing the immunogen sequence, this can be confirmed.

Read More
Answer

Thank you for your enquiry. Unfortunately, the immunogen information for this product is proprietary and cannot be released. However, an alignment with accession numbers Q75755 (JRFL) and D1G2M6 (NL4-3) was performed but there was very low homology with 18% and 6%, respectively.
