Panorama p53 Pathways Antibody Array, for studying the expression patterns of proteins known to be involved in p53 pathways, enables the analysis of cell or protein extracts and contains 112 antibodies spotted in duplicate onto a nitrocellulose slide along with Cy3 and Cy5 positive controls and a negative control. The recognition of p53 as a pivotal regulatory protein involved in a variety of signaling pathways is crucial to understanding the development and progression of cancer. This array will enable researchers to study the complex nature of p53 pathways in an efficient manner and allow the identification of protein expression patterns that may be related to cancer.
