Synonyms
G2/mitotic-specific cyclin-B1, cyclin B1, CCNB.
Introduction
Cyclin B1 (CCNB1) is a regulatory protein involved in mitosis. CCNB1 creates a complex with p34(cdc2) to form the maturation-promoting factor (MPF). CCNB1 is vital for the control of the cell cycle at the G2/M (mitosis) transition. CCNB1 builds up steadily during the G2 and is immediately destroyed at mitosis. The 2 alternative transcripts produce a constitutively expressed transcript and a cell cycle-regulated transcript which is expressed predominantly during G2/M phase. These transcripts are a result of alternate transcription initiation sites.
Description
CCNB1 Human Recombinant produced in E. coli is a single polypeptide chain containing 457 amino acids (1-433) and having a molecular mass of 50.9 kDa.
CCNB1 is fused to a 24 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Source
E.coli.
Physical Appearance
Sterile Filtered colorless solution.
Formulation
The CCNB1 solution (0.25mg/1ml) contains 20mM Tris-HCl buffer (pH 8.0), 150mM NaCl and 10% glycerol.
Stability
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Purity
Greater than 80% as determined by SDS-PAGE.
