P21 Peptide 25mg Liquid Spray 15ml Bottle (250mcg per Spray)

P21, also known as cyclin-dependent kinase inhibitor 1 (CDKI1), is a crucial regulatory protein that plays a significant role in the cell cycle by inhibiting cyclin-dependent kinases (CDKs). This peptide is predominantly expressed in response to various stress signals, including DNA damage and oncogenic stress, serving as a pivotal mediator in the cellular response to these stimuli. By halting the cell cycle, P21 helps maintain genomic stability and prevents the proliferation of damaged cells, thus acting as a tumor suppressor. Its dysregulation is often associated with various cancers, making P21 a focus of research for potential therapeutic interventions in cancer treatment and other diseases characterized by uncontrolled cell growth.

P21 Peptide is a laboratory-developed peptide studied in neuroscience and biochemical research. Scientists investigate this compound for its potential role in neurological signaling pathways, cellular communication, and cognitive-related research models.

The P21 Peptide 25mg Liquid Spray 15ml Bottle offers a convenient liquid formulation designed for laboratory studies. Each spray delivers approximately 250mcg, providing researchers with controlled dosing during experimental protocols. Liquid spray formats are commonly used in peptide research because they allow accurate dispensing and consistent handling.
