分子别名（Synonym）:CST6,EPM1,EPM1A,PME,STFB,ULD

种属（Species）：Human

表达系统（Expressed Host）：E. coli

产品状态（Buffer）：Lyophilized from sterile 50mM Tris, 50mM NaCl, pH 8.0

分子量（Molecule Mass）：The recombinant human CSTB consisting of 108 amino acids and has a calculated molecular mass of 12.5 kDa. It migrates as an approximately 15 kDa band in 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 inhibit papain cleavage of a fluorogenic peptide substrate Z-FR-AMC (RCat:D Systems, Catalog # ES009). The IC50 value is < 15 nM.

表达区间（Protein Construction）：A DNA sequence encoding the human CSTB (P04080) (Met 2-Phe 98) was expressed, with a polyhistide tag at the N-terminus.

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.
