This product is an affinity purified antibody produced by immunoaffinity chromatography using phospho peptide coupled to agarose beads followed by solid phase adsorption(s) against non-phospho peptide and non-specific peptide to remove any unwanted reactivities. This antibody is specific for phosphorylated human Cyclin B1 protein at the pS126 residue. BLAST analysis indicates 100 % homology of the immunizing sequence with Cyclin B1 from human. Cross reactivity may occur with Cyclin B1 from rat, dog and chimpanzee as only a single amino acid change was detected within the immunogen sequence from these sources (91 % homology). Partial reactivity may also occur with Cyclin B1 from mouse and hamster where two amino acids changes was noted (83 % homology). Minimal reactivity is expected with the non-phosphorylated form of the protein.

应用备注
This affinity purified antibody has been tested for use in ELISA (1: 10,000-1: 50,000) andWestern blot (1: 100-1: 1,000). Specific conditions for reactivity should be optimized by theend user. Expect a band approx. 48 kDa in size corresponding to Cyclin B1 by western blotting inthe appropriate cell lysate or extract. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

Cyclin B1 (also called CCNB1 and G2/mitotic-specific cyclin B1) is a regulatory protein involved in mitosis. The gene product complexes with p34(cdc2) to form a serine/threonine kinase holoenzyme complex called the maturation-promoting factor (MPF). Two alternative transcripts have been found a constitutively expressed transcript and a cell cycle-regulated transcript that is expressed predominantly during G2/M phase. The different transcripts result from the use of alternate transcription initiation sites. S126 phosphorylation, the site of phosphorylation recognized by this antibody, is involved in an auto-phosphorylation of the cdk -cyclin complex. Recognition of this phosphorylated site suggests the antibody is useful to detect the active form of the complex and may serve as a marker of mitosis.Synonyms: CCNB, CCNB1, Cyclin-B1, G2/mitotic-specific cyclin-B1
