{"product_id":"nsj-f54937-0-4ml","title":"p21WAF1 Antibody \/ CDKN1A, 0.4 ml","description":"\u003cp\u003eCDKN1A is a potent cyclin-dependent kinase inhibitor. It binds to and inhibits the activity of cyclin-CDK2 or -CDK4 complexes, and thus functions as a regulator of cell cycle progression at G1. Expression 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.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"0.4 ml","offer_id":51552457064728,"sku":"F54937-0.4ML","price":439.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_2dd994a8-3a6c-487f-9d2e-55529d89f954.jpg?v=1768355359","url":"https:\/\/danabiosci.com\/products\/nsj-f54937-0-4ml","provider":"Dana Bioscience","version":"1.0","type":"link"}
