Tumor Protein 53 (P53) ELISA Kit

  • Created on the 28 March, 2017.


Human P53 ELISA kit is intended for analysing in vitro quantitative concentrations of tumor protein 53 (P53) in human cell lysates. This assay has a minimum detection limit of < 10.0 pg/ml.


P53 which can also be called tumor protein 53, cellular tumor antigen p53, protein 53, phosphoprotein p53, transforming related protein p53 and tumor suppressor p53, in humans has several domains, is 393 amino acids long and runs as a 53 kDa protein on SDS-PAGE. It is essentially a tumor suppressor protein which in human is encoded by the TP53 gene and can be found mapped to chromosome 17. It can be activated in response to myriad stressors, such as oxidative stress, DNA damaging agents (UV, IR and many other chemical agents), osmotic shock, deregulated oncogene expression and ribonucleotide depletion. One of the most critical event leading to the activation of p53 is the phosphorylation of its N-terminal domain. This N-terminal transcriptional activation domain has a large number of phosphorylation sites and these are viewed as the primary target for protein kinases transducing stress signals.

The TP53 gene is frequently identified as a mutated gene (greater than 50%) in human cancers and this has led to associating TP53 gene to playing a crucial role in preventing cancer formation. This gene also encodes proteins that have the ability to bind to DNA and help to regulate gene expression in order to prevent mutations of the genome. The p53 molecule plays vital roles in apoptosis, inhibiting angiogenesis, genomic stability and a number of mechanisms that are involved in anti-cancer functions. The following P53 ELISA kit is designed for analysing various diagnostic applications.


The minimum detection sensitivity level of tumor protein 53 using current human P53 ELISA kit was 10.0 pg/ml. The dynamic range for this assay is 156.0 – 10,000 pg/ml.

Your secretory IgA ELISA kit gave good results and I was also really impressed with how quickly we received it.

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA kit performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA kits from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.

You are my first point of contact when I am looking to purchase ELISA kits. You have such an easy and simple system, yet it is very effective.
