BD, 554174, Purified Mouse Anti-Human Cyclin A BF683

Cyclins and cyclin-dependent kinases (cdks) are evolutionarily conserved proteins that are essential for cell-cycle control in eukaryotes. Cyclins (regulatory subunits) bind to cdks (catalytic subunits) to form complexes that regulate the progression of the cell cycle. The main cyclin-cdks complexes formed in vertebrate cells are cyclin D-cdk4 (G0/G1), cyclin E-cdk2 (G1/S), cyclin A-cdk2 (S) and cyclin B1-cdk1 (G2/M). These complexes are regulated by activating and inhibitory phosphorylation events, as well as by interactions with small regulatory proteins including p21 and p27Kip1. Specific substrates for cdk-cyclin complexes include nuclear lamins, histones, oncogenes (e.g., c-abl and SV40 large T-Ag), tumor suppressor genes (e.g., retinoblastoma protein, Rb), nucleolin and others. Cyclin A is involved in both S-phase and G2/M transitions of the cell cycle through its association with cdk2 and cdk1, respectively. Cyclin A may also form a complex with the adenovirus oncoprotein E1A which has DNA binding activity. Human cyclin A has been reported to migrate between 54-60 kDa by SDS-PAGE and clone BF683 reportedly does not cross-react with mouse, rat or mink cyclin A.

Store undiluted at 4°C. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
