General description
Cyclin-dependent kinase inhibitor 2A (UniProt: P42771; also known as Cyclin-dependent kinase 4 inhibitor A, CDK4I, Multiple tumor suppressor 1, MTS-1, p16-INK4a, p16-INK4, p16INK4A) is encoded by the CDKN2A (also known as CDKN2, MTS1) gene (Gene ID: 1029) in human. p16 serves as a negative regulator of cell proliferation by strongly interacting with CDK4 and CDK6 during the G1-to S-phase transition and blocking the phosphorylation of retinoblastoma (Rb) protein. Hence, it is considered as a tumor suppressor protein. Hypo-phosphorylated Rb protein forms complexes with E2F family of transcription factors, which sequesters E2Fs and prevent their access to the promoters of proliferation-associated genes. During cell cycle, in the late G1 phase CDK4 and CDK6 hyper-phosphorylate Rb protein that commits cells to enter into S phase. Binding of p16 maintains Rb in a hypo-phosphorylated state. CDKN2A gene is reported to be one of the most frequently mutated genes and is reported to be inactivated in about 50% of all human cancers. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Biochem/physiol Actions
Clone D25 is a ZooMAb® mouse recombinant monoclonal antibody that specifically detects Cyclin-dependent kinase inhibitor 2A (p16).
Physical form
Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.
Preparation Note
Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
