p27 Kip1 Antibody (SX53G8.5) is a mouse monoclonal IgG1 antibody that detects p27 Kip1 in mouse, rat, and human samples through various applications including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and immunohistochemistry. p27 Kip1 plays a crucial role as a negative regulator of cell cycle progression, particularly during the G1 phase, where p27 Kip1 inhibits the activity of cyclin-dependent kinases (Cdks) by binding to D-type cyclins and Cdk4, thereby preventing the transition to the S phase. This regulation is vital for maintaining proper cell growth and division, especially in response to external signals such as transforming growth factor-beta (TGFβ), which can induce G1 arrest. The ability of p27 Kip1 to modulate cell cycle progression highlights its importance in tumor suppression, as dysregulation of p27 Kip1 can lead to uncontrolled cell proliferation and cancer development. Anti-p27 Kip1 antibody (SX53G8.5) serves as an essential tool for researchers studying cell cycle dynamics and the molecular mechanisms underlying various diseases.

I am using p27 (SX53G8.5) monoclonal antibody to stain snap-frozen sections. Would I be able to do a quick IF staining (to preserve the RNA) or would I need to use antigen retrieval procedures? Also, what is the recommended dilution?

Asked by: Amber12
Thank you for your question. If you are fixing in formalin or pfa that would cause cross-linking, I would suggest performing an antigen retrieval step. The recommended starting dilution is 1:50 for IF and IHC applications.

I am using p27 (SX53G8.5): sc-53871 monoclonal antibody to stain paraffin embedded tissue. Do you recommend antigen retrieval when using this antibody?

Asked by: jerojero
We recommend performing antigen retrieval with sodium citrate buffer (pH 6) and heat. The full protocol can be found here: https://www.scbt.com/scbt/resources/protocols/immunoperoxidase-staining
