Datasheets
  • CDKN3 Antibody (39) is a mouse monoclonal IgG1 κ CDKN3 antibody provided at 200 µg/ml
  • raised against amino acids 1-212 representing full length CDKN3 of human origin
  • recommended for detection of CDKN3 of mouse, rat, human and avian origin by WB, IP and IF; also reactive with additional species, including canine and avian
  • m-IgGκ BP-HRP is the preferred secondary detection reagent for CDKN3 Antibody (39) for WB applications. This reagent is now offered in a bundle with CDKN3 Antibody (39) (see ordering information below). For additional m-IgGκ BP conjugates see our complete list of Mouse IgG Binding Proteins.

CDKN3 Antibody (39) is a mouse monoclonal IgG1 kappa light chain antibody that detects CDKN3 protein of mouse, rat, and human origin by western blotting (WB), immunoprecipitation (IP), and immunofluorescence (IF). anti-CDKN3 antibody (39) is available as the non-conjugated format. Cyclin-dependent kinase inhibitor 3 (CDKN3), also known as Cdk2-associated dual specificity phosphatase, cyclin-dependent kinase interactor 1 (CDI1), CIP2, KAP, or KAP1, is a member of the protein-tyrosine phosphatase family and plays a crucial role in cell cycle regulation. CDKN3 is primarily located in the nucleus, where CDKN3 is essential for controlling the progression of the cell cycle by regulating the activity of cyclin-dependent kinases (CDKs). Nuclear localization of CDKN3 allows for precise modulation of CDK activity, which is vital for maintaining proper cell division and preventing uncontrolled proliferation. CDKN3 interacts with and dephosphorylates Cdk2 kinase, thereby inhibiting activation and ensuring that cells do not prematurely enter the S phase of the cell cycle. Dysregulation of CDKN3 has been implicated in various cancers, as mutations, overexpression, or deletions of the CDKN3 gene can lead to aberrant cell cycle progression and tumorigenesis. The gene encoding CDKN3 is located on chromosome 14q22, and proper function is critical for cellular homeostasis and cancer prevention.

I am using CDKN3 (39): sc-135864 for immunofluorescence, what dilution of this antibody should I use?

Asked by: Dr Ninau Qelp
Thank you for your question. We recommend a starting dilution of 1:50. However, optimal antibody concentration should be determined by titration. Please find our full immunofluorescence protocol here: https://www.scbt.com/scbt/resources/protocols/immunofluorescence-cell-staining
