Cyclin-dependent kinase 4 (UniProt: P11802; also known as EC:2.7.11.22, Cell division protein kinase 4, PSK-J3) is encoded by the CDK4 gene (Gene ID: 1019) in human. Cdk4 is a serine/threonine protein kinase that serves as a component of the cyclin D-Cdk-4 complexes that phosphorylates and inhibit members of the retinoblastoma (RB) protein family, including RB1, and regulate the cell-cycle during G1/S transition. Phosphorylation of RB1 allows dissociation of the transcription factor E2F from the RB/E2F complexes and the subsequent transcription of E2F target genes which are responsible for the progression through the G1 phase. Cyclin D-Cdk4 complexes are major integrators of various mitogenic and antimitogenic signals. Cdk4 is also reported to phosphorylate SMAD3 in a cell-cycle-dependent manner and represses its transcriptional activity. Its protein kinase domain is localized in amino acids 6-295 and amino acids 50-56 are required for its binding to D-type cyclins. Its phosphorylation at threonine 172 and binding of a D-type cyclin are shown to be essential for its enzymatic activity. Full activation of the cyclin-D-CDK4 complex appears to require other factors such as recruitment of the substrate via a substrate recruitment motif, and/or formation of the Cyclin Dependent Kinase Inhibitor 1B (CDKN1B) ternary complex. Formation of this complex is also essential for its translocation to the nucleus. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

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.

300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

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.
