Human CDKN1A (Cyclin-dependent kinase inhibitor 1) ELISA KIT (HUFI05329)

The Assay Genie Human CDKN1A ELISA Kit enables quantitative measurement of cyclin-dependent kinase inhibitor 1, commonly known as p21 (also called CIP1 or WAF1), a ~21 kDa regulatory protein encoded on chromosome 6p21.2. CDKN1A functions as a primary downstream effector of p53, enforcing cell cycle arrest at the G1/S checkpoint following DNA damage. It serves as a key biomarker in studies of tumor suppression, cellular senescence, apoptosis regulation, and the DNA damage response.

This microplate-format assay is intended for research use only and is widely applied across oncology, cell biology, and aging research. The kit supports batch processing in a standard well plate footprint and provides reproducible quantification. Reagents are supplied ready-to-use, with refrigerated storage recommended to preserve reagent stability across the shelf life of the unopened components. The workflow accommodates cell lysate, tissue homogenate, and culture supernatant samples, supporting both individual experiments and high-throughput study designs.
