Western blot analysis using CCNB1 polyclonal antibody (Cat # PAB9943) shows detection of CCNB1 present in asynchronous HeLa cell lysates. Comparison to a molecular weight marker indicates a band of ~55 KDa corresponding to human CCNB1 (arrowhead). Approximately 50 ug of lysate was loaded on to a 7% SDS-PAGE gel for separation. After transfer to nitrocellulose, the blot was incubated with a 1 : 500 dilution of the antibody for 1 h at room temperature. Detection occurred using a 1 : 10,000 of HRP conjugated Goat-a-Rabbit IgG. Personal communication, Luca D'Agostino, Temple University, Philadelphia, PA.
Western Blot (Cell lysate)
Western blot analysis using CCNB1 polyclonal antibody (Cat # PAB9943) antibody shows detection of human CCNB1 present in asynchronous HN30 cell lysates. HN30 cells are from head and neck cancer tumors that over express CCNB1 and D1. Comparison to a molecular weight marker indicates a band of ~62 KDa corresponding to the expected molecular weight for the protein (arrowhead). The blot was incubated with a 1 : 500 dilution of the antibody for 1 h at room temperature. Detection occurred using a 1 : 10,000 of HRP conjugated Goat-a-Rabbit IgG and chemiluminescence reagent with a 1-min exposure time.

Immunohistochemical staining with CCNB1 polyclonal antibody (Cat # PAB9943) was diluted 1 : 500 to detect CCNB1 in human brain cerebellum tissue. Tissue was formalin fixed and paraffin embedded. No pre-treatment of sample was required. The image shows the localization of antibody as the precipitated red signal, with a hematoxylin purple nuclear counter stain.
The protein encoded by this gene is a regulatory protein involved in mitosis. The gene product complexes with p34(cdc2) to form 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. [provided by RefSeq
