| Formulation |
Procalcitonin was filtered (0.4um) and lyophilized in 20mM TRIS and 50mM NaCl, pH 8.0. |
| Solubility |
It is recommended to add 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. |
| Purity |
Greater than 95.0% as determined by SDS-PAGE. |
| Description |
Procalcitonin Rat Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain (Val26-Asn136) containing 121 amino acids including a 10 aa His tag at N-terminus. The total calculated molecular mass is 13.6kDa. |
| Protein Background |
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. |
| Expression host |
Escherichia Coli. |
| Synonyms |
Calcitonin, Calca, Calc. |
| Reagent Appearance |
Filtered White lyophilized (freeze-dried) powder. |
| Stability |
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. |
