Recently two genes, termed p63 and p73, have been have been identified and found to encode proteins that share a significant amino-acid identity in the transactivation domain, the DNA binding domain, and the oligomerization domain with p53. Both p63 and p73 can bind to canonical p53-DNA-binding sites, transactivate the promoters of known p53 target genes and induce apoptosis. p63 encodes for different isotypes able to either transactivate p53 reporter genes (TAp63) or act as p53-dominant-negatives (DeltaNp63). DeltaNp63 are preferentially expressed in the epithelial basal cells of different organs and have been considered as possible markers of stem cells/reserve cells.
Positive Control: A549 or Jurkat
Applications:
Suitable for use in Western Blot. Other applications not tested.
Recommended Dilution:
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot Store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
