  • Relevance

    E7 protein has both transforming and trans-activating activities. Disrupts the function of host retinoblastoma protein RB1/pRb, which is a key regulator of the cell cycle. Induces the disassembly of the E2F1 transcription factors from RB1, with subsequent transcriptional activation of E2F1-regulated S-phase genes. Inactivation of the ability of RB1 to arrest the cell cycle is critical for cellular transformation, uncontrolled cellular growth and proliferation induced by viral infection. Stimulation of progression from G1 to S phase allows the virus to efficiently use the cellular DNA replicating machinery to achieve viral genome replication. Interferes with histone deacetylation mediated by HDAC1 and HDAC2, leading to activation of transcription

Thank you for your enquiry and your interest in our products.

These two monoclonal antibodies recognize the same protein (Human Papillomavirus 16 (E7)) but are from different clones.



As you can see on the datasheets, the concentration, the tested application and the storage buffer are different.

If you need any further assistance in the future, please do not hesitate to contact me.

Thank you for your call today and for your questions about ab20191.

I have done a search on google scholar for the clone TVG 701Y, and there are several publications listed:


I have downloaded the pdf files for the first two listings and attached them to this email.

I hope this information will be helpful in determining whether this antibody will work with your studies. If there is anything else that we can do for you, please don't hesitate to ask. Have a great weekend!

Thank you for contacting Abcam.   I have contacted the lab about ab20191, which is a Human Papillomavirus 16 (E7) antibody [TVG701Y] and can be used in flow cytometry and western blot. However the lab has told me that we do not know what the immunogen sequence is for this antibody.   This paper might be of help to you though:   http://www.ncbi.nlm.nih.gov/pubmed?term=8380917    If there is anything else I can help you with, please let me know.
