CaProcalcitonin Recombinant Protein

Source : Escherichia Coli. Procalcitonin Canine Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain (Ala26-Arg130) containing 115 amino acids including a 10 aa His tag at N-terminus. The total calculated molecular mass is 12.7kDa. Procalcitonin is a peptide hormone mainly produced by the C cells of the thyroid and certain endocrine cells of the lung. Under normal expression conditions, procalcitonin is immediately cleaved into three specific fragments, an N terminal residue, calcitonin and katacalcin. Levels of unprocessed procalcitonin rise significantly after bacterial infection, trauma or shock.

Product Specifications

Product Name Alternative

Calcitonin||Calca||Calc||CCALCI.

Purification

Greater than 90.0% as determined by SDS-PAGE.

Components

Procalcitonin was filtered (0.4μm) and lyophilized in 20mM TRIS and 50mM NaCl, pH 7.2.

Storage Conditions

Store lyophilized protein at -20°C. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles. Reconstituted protein can be stored at 4°C for a limited period of time; it does not show any change after two weeks at 4°C.

Applications Notes

It is recommended to add 200μl deionized water to prepare a working stock solution of approximately 0.5 mg/ml and let the lyophilized pellet dissolve completely. Procalcitonin is not sterile! Please filter the product by an appropriate sterile filter before using it in the cell culture.
