重组人降钙素(Human Procalcitonin)

Procalcitonin Human
Procalcitonin Human Recombinant
Catalog No. HOR-304

Synonyms:
Procalcitonin, PCT.

Introduction:
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.

Description:
Procalcitonin Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 116 amino acids and having a molecular mass of 12.7 kDa.
The Procalcitonin is purified by standard chromatographic techniques.

Source:
Escherichia Coli.

Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation:
Lyophilized from 10mM sodium phosphate pH-7.5

Solubility:
It is recommended to reconstitute the lyophilized procalcitonin sterile 18MΩ-cm H2O at 100 µg/ml, which can then be further diluted to other aqueous solutions.

Stability:
Lyophilized procalcitonin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution procalcitonin should be stored at 4°C between 2-7 days and for future use below -18°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.

Purity:
Greater than 97.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Amino acid sequence:
APFRSALESS PADPATLSED EARLLLAALV QDYVQMKASE LEQEQEREGS SLDSPRSKRC GNLSTCMLGT YTQDFNKFHT FPQTAIGVGA PGKKRDMSSD LERDHRPHVS MPQNAN.

Biological Activity:
Human Procalcitonin was tested using Biomerieux reagents on the Min-Vidas.
The assay was run at 80 ng/ml with a recovery of 82 percent.

Usage:
Prospec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
