Human Arylsulfatase A / ARSA Protein (His Tag)

分子别名（Synonym）:MLD种属（Species）：Human表达系统（Expressed Host）：HEK293 Cells制剂（Buffer）：Lyophilized from sterile 25mM Tris, 0.15mM NaCl, pH 7.5分子量（Molecule Mass）：The recombinant human ARSA consists of 500 amino acids and predicts a molecular mass of 53 kDa. as estimated by SDS-PAGE under reducing conditions.内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method.生物活性(Activity)：Measured by its ability to hydrolyze the substrate 4-Nitrocatechol Sulfate (PNCS)表达区间（Protein Construction）：A DNA sequence encoding the human Arylsulfatase A (NP_000478.2) (Ser 2-Ala 507) was expressed with a C-terminal polyhistidine tag.存储条件（Storage）：For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution.运输条件：In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
