名称: 原装|Recombinant Human DNA Fragmentation Factor Subunit Alpha
Description DFFA Human Recombinant fused with 20 amino acid His tag at N-terminus produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 351 amino acids (1- 331 a.a.) and having a molecular mass of 38.7kDa.
The DFFA is purified by proprietary chromatographic techniques.
Source Escherichia Coli.
Physical Appearance Sterile Filtered colorless solution.
Formulation The DFFA solution contains 20mM Tris-HCl buffer (pH 8.0), 10% glycerol and 1mM DTT.
Stability DFFA although stable 4°C for 4 weeks, should be stored desiccated below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
Purity Greater than 90.0% as determined by SDS-PAGE.
