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 chromatog

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 progre

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.
