Introduction
M-phase inducer phosphatase 1 (CDC25A), a member of the CDC25 phosphatase family, plays a crucial role in cell cycle progression from the G1 to the S phase. It activates cyclin-dependent kinase CDC2 by removing two phosphate groups, thereby promoting cell cycle advancement. In response to DNA damage, CDC25A undergoes degradation, preventing cells with chromosomal abnormalities from proceeding through cell division. While recognized as an oncogene, the precise role of CDC25A in oncogenesis remains to be fully elucidated.
Description
Recombinant human CDC25A, expressed in E. coli, is a single, non-glycosylated polypeptide chain with a molecular weight of 63.2 kDa. It consists of 560 amino acids (1-524 a.a.) and includes a 36 amino acid His tag at the N-terminus. Purification of CDC25A is achieved through proprietary chromatographic techniques.
Physical Appearance
A clear, colorless solution that has been sterilized by filtration.
Formulation
The CDC25A solution is provided at a concentration of 0.25 mg/ml in a buffer consisting of 20mM Tris-HCl (pH 8.0), 5mM DTT, 20% glycerol, 0.2M NaCl, and 1mM EDTA.
Stability
For short-term storage (up to 2-4 weeks), the product can be stored at 4°C. For extended storage, it is recommended to freeze the product at -20°C. To ensure long-term stability during frozen storage, the addition of a carrier protein (0.1% HSA or BSA) is advised. Repeated freezing and thawing of the product should be avoided.
Purity
The purity of CDC25A is determined by SDS-PAGE analysis to be greater than 80.0%.
Synonyms
M-phase inducer phosphatase 1, Dual specificity phosphatase Cdc25A, CDC25A, CDC25A2.
