Introduction
Anamorsin, also known as CIAPIN, belongs to the anamorsin protein family. Its primary expression is observed within the cytoplasm of cells in the liver, pancreas, and heart tissues. Notably, CIAPIN does not exhibit homology with recognized apoptosis regulators like Bcl-2 or CASP families, nor with signal transduction molecules. The expression of CIAPIN1 is dependent on stimulation by growth factors. This ubiquitously expressed protein, when overexpressed, confers resistance to apoptosis.
Description
Recombinant human CIAPIN1, produced in E. coli, is a single, non-glycosylated polypeptide chain consisting of 335 amino acids (specifically, amino acids 1 to 312). It possesses a molecular weight of 36 kDa. For purification purposes, CIAPIN1 is tagged with a 23 amino acid His-tag at its N-terminus and subsequently purified using proprietary chromatographic methods.
Physical Appearance
The product is a clear solution that has undergone sterile filtration.
Formulation
The CIAPIN1 protein solution is provided at a concentration of 1 mg/ml. It is formulated in a buffer consisting of 20mM Tris-HCl (pH 8.0), 0.4M Urea, and 10% glycerol.
Stability
For short-term storage (up to 2-4 weeks), the product should be kept at 4°C. For extended storage, it is recommended to freeze the product at -20°C. To ensure optimal stability during long-term storage, consider adding a carrier protein (0.1% HSA or BSA). It is crucial to avoid subjecting the product to repeated cycles of freezing and thawing.
Purity
The purity of the CIAPIN1 protein is determined to be greater than 90% based on SDS-PAGE analysis.
