Recently, it has been shown that cyclin B1 was degraded mainly before the onset of anaphase in mammalian cells. When a nondegradable form of cyclin B1 was introduced into cells, the metaphase-anaphase transition was blocked. This blockage was not due to a failure in activating anaphase-promoting complex, nor was it due to a failure of degradation of securin. To resolve the question of whether

In mammals, Cyclin B is a subunit for the cdc2 (Cdk1) protein kinase and is synthesized during late S and G2 phases.

In addition, cyclin A has been implicated in cell transformation and is found in complexes with E1A, transcription factors DRTF1 and E2F and retinoblastoma protein, p110.

This blockage was not due to a failure in activating anaphase-promoting complex, nor was it due to a failure of degradation of securin. To resolve the question of whether Anti-cyclin B1 Antibody (GNS1) is a mouse monoclonal IgG 1 κ cyclin B1 antibody, cited in 1,089 publications, provided at 200 µg/ml raised against a recombinant protein corresponding to human cyclin B1 Anti-cyclin B1 Antibody (GNS1) is recommended for detection of cyclin B1 of mouse, rat and human origin by WB, IP, IF and IHC (P) Western blot analysis of extracts from HT-29 cells, synchronized in S-phase by double thymidine block (2 nM, 16 hr) followed by release into fresh media for the indicated time, using Cyclin B1 (D5C10) XP ® Rabbit mAb (upper) or β-Actin (D6A8) Rabbit mAb #8457 (lower). several B-type cyclins. Although Cyclin B proteins are synthesized and can interact with Cdc2 during inter-phase, Cdc2/Cyclin B complexes are held in an inactive state until the G 2 /M transition. This inactivation of Cdc2/Cyclin B during interphase is achieved through in-hibitory phosphorylation of the Cdc2 subunit on Thr-14 Etymology. Cyclins were originally discovered by R. Timothy Hunt in 1982 while studying the cell cycle of sea urchins.. In an interview for "The Life Scientific" (aired on 13/12/2011) hosted by Jim Al-Khalili, R. Timothy Hunt explained that the name "cyclin" was originally named after his hobby cycling.

1 Mar 2011 We overcame the need to use transfected cells by transducing B-cell lines with TAT-cyclin D1 fusion proteins. The “protein transduction domain” (

Zyklon B (German: [tsyˈkloːn ˈbeː] (listen); translated Cyclone B) was the trade name of a cyanide-based pesticide invented in Germany in the early 1920s. It consisted of hydrogen cyanide (prussic acid), as well as a cautionary eye irritant and one of several adsorbents such as diatomaceous earth. Cdk1/ cyclin B (also referred to as maturation promoting factor or MPF) is one of the main protein kinases that becomes activated and serves as master regulator for the M-phase transition, phosphorylating and activating other downstream protein kinases, and directly posphorylating several structural proteins involved in cellular reorganization. Cyclin B1, a key component in the control of cell cycle progression from G2 to M phase, has been implicated in the tumorigenesis and the development of malignancy.

Cyclin B is essential for sister‐chromatid segregation and cytokinesis. We subsequently analysed the phenotypes of cells lacking B‐type cyclins in closer detail. DIA‐treated B1 dd /B2 ko cells readily entered mitosis, but failed to undergo sister‐chromatid segregation and cytokinesis (Figs 3A and EV2).

Previously, we showed that the destruction of cyclin B was initiated by the Synthetic peptide within Mouse Cyclin B1 aa 350-450 conjugated to keyhole limpet haemocyanin. The exact immunogen sequence used to generate this antibody is proprietary information.

Cyklin B je souhrnné označení pro nejméně tři typy savčích cyklinů – cyklin B1, cyklin B2 a cyklin B3.Cyklin B1 má zásadní funkci v tzv. G 2 /M přechodu (mezi G 2 fází a mitózou), zatímco cykliny B2 a B3 hrají méně zřejmé role v přípravě na mitózu či meiózu.
