Introduction
FAM50A, a member of the FAM50 family, exhibits high conservation in length and sequence across various species. As a basic protein, it contains a nuclear localization signal and possesses potential functionality as a DNA-binding protein or a transcriptional factor. FAM50A is ubiquitously expressed, with notable abundance in fetal brain, liver, and kidney. In adults, elevated levels are observed in skeletal muscle, spleen, thymus, prostate, and the small intestine.
Description
Recombinant FAM50A, produced in E. coli, is a single, non-glycosylated polypeptide chain comprising 213 amino acids (residues 150-339). With a molecular weight of 25.2 kDa, it features a 23 amino acid His-tag fused at the N-terminus. Purification is achieved using proprietary chromatographic methods.
Physical Appearance
The product is a sterile, colorless solution.
Formulation
The FAM50A protein solution (0.5 mg/ml) is supplied in a buffer containing 20 mM Tris-HCl (pH 8.0), 0.15 M NaCl, 20% glycerol, and 1 mM DTT.
Stability
For short-term storage (2-4 weeks), the product should be kept at 4°C. For extended storage, freezing at -20°C is recommended. Adding a carrier protein (0.1% HSA or BSA) is advisable for long-term storage. Repeated freeze-thaw cycles should be avoided.
Purity
The purity of the product is greater than 90% as determined by SDS-PAGE analysis.
Synonyms
9F, DXS9928E, HXC-26, HXC26, XAP5, XAP-5.
