  • Relevance
    Two retinoblastoma related proteins, p107 and pRb2 / p130, which are structurally and functionally similar to the product of the retinoblastoma gene (pRb / p105), were cloned by taking advantage of their ability to bind transforming proteins of DNA tumor viruses through a particular region called the "pocket domain." Like pRb, both proteins play a fundamental role in growth control. These Rb family proteins were measured in a variety of lung neoplasms. The highest percentage of undetectable levels and the tightest inverse correlation with the histological grading and with PCNA expression in the most aggressive tumor types were found for pRb2 / p130, which may suggest an important role for this protein in the pathogenesis and progression of lung cancer.

  • ab6545 staining Rb2 p130 in Mouse lung tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with 4% paraformaldehyde in PBS at 4°C overnight, embedded in paraffin was and section a 7μm. Endogenous enzyme activity was quenched by 2% H2O2 in methanol (30 minutes). Sections were blocked wirh 2% BSA, 5% serum and 0.1% Trition X-100 in PBS. Samples were incubated with primary antibody (1/500 in blocking buffer). White arrow heads mark epithelial cells expressing high levels of protein in nuclear and perinuclear locations.

Thank you for contacting Abcam and for your help in finding the associated proteins on the phone.

I have had the chance to run the alignments of these proteins and have found that the homology between them is extremely poor. As such I do not believe that you will be able to find a single product which recognizes all targets. I have compiled a short list of products which re against each protein and are suitable for western blot on rat tissues for you.

RB1 (alternative names include:p105-Rb,Osteosarcoma)



RB2 (alternative names include: Rb2 p130, RBL2)



RB3 (alternative names include:Stathmin like 4, STMN4)


I hope that this information is helpful. Please let me know if you have any questions or there are other ways that Abcam may help you meet your research goals.

Thank you for your enquiry. I have enquired at the originator of the product but unfortunately, the immunogen sequence is not available, but this polyclonal antiserum recognizes epitopes in the C-terminus region of Rb2(p130). I hope this information will still be helpful.

I was unfortunately unable to cannot find any supplier of this protein. The protein appears to be commonly expressed in most cell lines (including mouse 3T3 lines). You may wish to use cell lysates from these cells if you require a control tissue. My apologies for the inconvenience,
