The antibody was conjugated to Alexa Fluor 647 under optimal conditions with an F\/P ratio of 2-5. The Alexa Fluor 647 dye is maximally excited by red light (e.g. 633 nm He-Ne laser). Antibody conjugates of the Alexa Fluor 647 dye produce bright far-red-fluorescence emission, with a peak at 665 nm.\n\u003cb\u003eBackground\u003c\/b\u003e\nCyclins are a family of proteins that activate specific cyclin-dependent kinases required for progression through the cell cycle. The entry of all eukaryotic cells into mitosis is regulated by activation of cdc2\/cdk1 at the G2\/M transition. This activation is a multi-step process that begins with the binding of the regulatory subunit, cyclin B1, to cdc2\/cdk1 to form the mitosis-promoting factor (MPF). MPF remains in the inactive state until phosphorylation of cdc2\/cdk1 at Thr161 by cdk activating kinase (CAK) (1,2) and dephosphorylation of cdc2\/cdk1 at Thr14\/Tyr15 by cdc25C (3-5). Five cyclin B1 phosphorylation sites (Ser116, 126, 128, 133, and 147) are located in the cytoplasmic retention signal (CRS) domain and are thought to regulate the translocation of cyclin B1 to the nucleus at the G2\/M checkpoint, promoting nuclear accumulation and initiation of mitosis (6-9). While MPF itself can phosphorylate Ser126 and Ser128, polo-like kinase 1 (PLK1) phosphorylates cyclin B1 preferentially at Ser133 and possibly at Ser147 (6,10). At the end of mitosis, cyclin B1 is targeted for degradation by the anaphase-promoting complex (APC), allowing for cell cycle progression (11). Research studies have shown that cyclin B1 is overexpressed in breast, prostate, and non-small cell lung cancers (12-14).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nCCNB; CCNB1; cyclin B1; G2\/mitotic-specific cyclin B1; G2\/mitotic-specific cyclin-B1\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M\nSENSITIVITY: Endogenous\nSource\/Isotype: Mouse IgG1","brand":"CST","offers":[{"title":"Default Title","offer_id":46800396877993,"sku":"4118S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-4118s","provider":"Iright","version":"1.0","type":"link"}
