| Formulation |
The ARSA solution (1mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 0.4M UREA and 10% glycerol. |
| Purity |
Greater than 90% as determined by SDS-PAGE. |
| Description |
ARSA Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 512 amino acids (21-509) and having a molecular mass of 54.3kDa.ARSA is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. |
| Protein Background |
Arylsulfatase A (ARSA) hydrolyzes cerebrosidesulfate to cerebroside and sulfate. ARSA is inhibited by phosphate. The phosphate develops a covalent bond with the active site 3-oxoalanine. ARSA gene defects cause metachromatic leucodystrophy (MLD), a progressive demyelination disease which results in various neurological symptoms and ultimately death. |
| Expression host |
Escherichia Coli. |
| Synonyms |
Arylsulfatase A, ASA, EC 3.1.6.8, Cerebroside-sulfatase, ARSA, MLD. |
| Reagent Appearance |
Sterile Filtered clear solution. |
| Stability |
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles. |
