Technical Data
K7965-05
Ku, p70, p80
Description:
The Ku autoantigen is a heterodimer of 70kD (p70) and ~80kD (p80) proteins. The p70/p80 dimer is important for function of a 460kD DNA-dependent protein kinase that phosphorylates certain transcription factors, including Sp1, Oct-1, p53, and SV40 large T antigen in vitro. Ku protein plays a role in cell signaling, proliferation, DNA repair, replication, transcriptional activation, and apoptosis.

Applications:
Suitable for use in Immunoprecipitation, Flow Cytometry, Immunofluorescence and Immunohistochemistry. Not suitable for Western Blot. Optimal dilutions to be determined by the researcher.

Recommended Dilution:
Immunohistochemistry (Formalin/paraffin): 1-2ug/ml for 30 minutes at RT. No special pretreatment is required for staining of formalin-fixed, paraffin-embedded tissues.
Immunoprecipitation: Tested only on mouse and rat
Optimal dilutions to be determined by the researcher.

Recommended Positive Control:
Tonsil

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
