  • Application notes
    Is unsuitable for IP.
  • Target

    • Relevance

      The human Cyclin E2 gene encodes a 404 amino acid protein that is most closely related to Cyclin E. Cyclin E2 mRNA levels peaks at the G1 / S transition. Cyclin E2 associates with Cdk2 in a functional kinase complex that is inhibited by both p27 (Kip1) and p21 (Cip1). Cyclin E2 / Cdk2 phosphorylates histone H1 in vitro. G1 cyclin E controls the initiation of DNA synthesis by activating CDK2. Abnormally high levels of cyclin E expression have frequently been observed in human cancers. Unlike Cyclin E1, which is expressed in great majority of proliferating normal and neoplastically transformed cells, Cyclin E2 levels are low to undetectable in non transformed cells and increase significantly in neoplasm derived cells.

There is too much cytoplasmic staining and some stromal background I must get rid of. I just wanted an idea of Abcam’s staining method for IHC so I don’t waste anymore precious tissue or reagent.

      Asked on Jul 09 2007

      Answer

      Thank you for your enquiry. I can confirm that this product does not require any specific protocols and the general IHC-P and antigen retrieval protocols found on our website (can also be accessed on the datasheet) will be able to help you. From the protocols you provided, I agree that you should try incubating at 4oC overnight to ensure proper and sufficient binding to the protein of interest. You can also try increasing the primary antibody dilution to 1:100 ~ 1:1000. The recommended dilution we have on the datasheet is just a guideline and optimal dilutions/concentrations should be determined by the end user. Can I also suggest running a no primary experiment? Sometimes, the problem lies with the secondary antibody and could be binding non-specifically to your sample. I hope the information above will helpful. Please do not hesitate to contact me again if you face problems when using this product.
