Application DetailsImmunohistochemistry (IHC) and Western Blotting (WB). A concentration of 0.5-1.0 µg/mL is recommended for WB. Human p53 (isoform 1) has a predicted length of 393 residues and MW of 44 kDa. A concentration of 0.5-2.0 µg/mL is recommended to detect p53 in formalin fixed and paraffin embedded tissues as well as formalin/acetone fixed frozen tissues. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.

Scientific Backgroundp53 is a DNA-binding protein containing transcription activation, DNA-binding and oligomerization domains. p53 is ubiquitously expressed and responds to a variety of cellular stresses to regulate target genes that induce cell cycle arrest, apoptosis, senescence, DNA repair or changes in metabolism. Multiple p53 variants are produced from alternative promoters and alternative splicing.
