Introduction
Erythrocyte acylphosphatase (ACYP1) is an enzyme found in the cytosol that breaks down acylphosphates by hydrolyzing their carboxyl-phosphate bond. Two isoenzymes of acylphophatase exist: ACYP1 and ACYP2. Despite sharing 60% homology and having the same substrate specificity, ACYP1 exhibits higher catalytic activity compared to ACYP2.
Description
Recombinant human ACYP1, expressed in E. coli, is a single, non-glycosylated polypeptide chain with a molecular weight of 13.6 kDa. It comprises 122 amino acids, including a 23 amino acid His tag at the N-terminus (amino acids 1-99). Purification of ACYP1 is achieved through proprietary chromatographic techniques.
Physical Appearance
Clear, colorless solution that has been sterilized by filtration.
Formulation
The ACYP1 solution is provided at a concentration of 1 mg/ml and is formulated in a buffer containing 20mM Tris-HCl (pH 8.0), 20% glycerol, 0.1M NaCl, and 1mM DTT.
Stability
For short-term storage (2-4 weeks), keep the ACYP1 vial refrigerated at 4°C. For extended storage, freeze the solution at -20°C. To enhance long-term stability, consider adding a carrier protein (0.1% HSA or BSA) to the solution. Repeated freezing and thawing cycles should be avoided.
Purity
The purity of ACYP1 is determined to be greater than 90% by SDS-PAGE analysis.
