{"product_id":"f51647-0-08ml","title":"p21 Antibody","description":"\u003cp\u003eThis gene encodes a potent cyclin-dependent kinase inhibitor. The encoded protein binds to and inhibits the activity of cyclin-CDK2 or -CDK4 complexes, and thus functions as a regulator of cell cycle progression at G1. The expression of this gene is tightly controlled by the tumor suppressor protein p53, through which this protein mediates the p53-dependent cell cycle G1 phase arrest in response to a variety of stress stimuli. This protein can interact with proliferating cell nuclear antigen (PCNA), a DNA polymerase accessory factor, and plays a regulatory role in S phase DNA replication and DNA damage repair. This protein was reported to be specifically cleaved by CASP3-like caspases, which thus leads to a dramatic activation of CDK2, and may be instrumental in the execution of apoptosis following caspase activation. Two alternatively spliced variants, which encode an identical protein, have been reported.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"0.08 ml \/ Rabbit","offer_id":49477586256152,"sku":"F51647-0.08ML","price":199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_a21bde73-f9f0-469f-82dd-d7c4cd4cdf08.jpg?v=1734497431","url":"https:\/\/danabiosci.com\/products\/f51647-0-08ml","provider":"Dana Bioscience","version":"1.0","type":"link"}
