||p53 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.

||Recombinant human wild-type p53 protein
||Cellular tumor antigen p53; Tumor suppressor p53; Phosphoprotein p53; NY-CO-13; TP53; P53;
||Immunohistochemistry (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.
||The specificity of this antibody has been confirmed by WB and IHC against the antigen.
||If you wish to use this product in a species other than those specified here and want to determine the amino acid sequence homology between the immunogen and the corresponding protein in that species, simply copy the amino acid sequence for this immunogen and test it on the BLAST database that you can access through the link below. Please note that antibodies raised against synthetic peptides are quite often very specific for that peptide. What this means in practise is that a single amino acid difference may be enough to restrict the specificity to a particular molecule. The BLAST database can also be used to compare any amino acid sequence between species and between protein. The full amino acid sequence of the target protein can be found by following the link in the Accession field. You can then search any amino acid sequence in the target protein using the BLAST database. When selecting a sequence to search, please choose carefully, as the sequence you choose may be a precursor rather than the mature protein for example.
||Lyophilized from 1.2% sodium acetate, 2mg BSA, 0.01mg NaN3
||Reconstitute in 1 ml of PBS (pH 7.4) to achieve an antibody concentration of 100 µg/ml. Centrifuge to remove any insoluble material.
