Manufacturer Direct Sale P21 Peptide P021 Biochemical Lab Raw Powder

Composition
p21, formally known as Cyclin-Dependent Kinase Inhibitor 1A (CDKN1A), is a naturally occurring protein encoded by the CDKN1A gene located on human chromosome 6.
It consists of a specific sequence of 164 amino acids and is structurally characterized as an intrinsically disordered protein, meaning it lacks a single, stable three-dimensional structure in its free state.
This structural flexibility allows it to adapt and bind to various molecular targets with high specificity.

Research Advantages
p21 is a pivotal molecule in molecular biology, oncology, and gerontology due to its central role in maintaining cellular integrity:
Tumor Suppression: It serves as a critical biomarker for evaluating the integrity of tumor suppressor pathways. Its expression levels are used to assess the potential for tumor differentiation, metastasis, and prognosis in various malignancies, including lung and breast cancer.
Cellular Senescence Indicator: p21 is a hallmark marker for cellular aging. It is extensively utilized in research to study the mechanisms of senescence and to develop strategies for clearing aged cells to improve tissue function.
Therapeutic Target: Due to its ability to arrest cell proliferation, p21 is a key subject in the development of cancer therapies and strategies for managing age-related chronic diseases
Applicable Contexts
p21 is exclusively utilized in controlled biomedical research and clinical pathology.
Its applications include the investigation of cancer biology, the study of genetic stability and DNA repair mechanisms, and the analysis of cellular aging processes.
In clinical diagnostics, the expression of p21 is assessed via immunohistochemistry to evaluate tumor characteristics and patient prognosis.
