Description: Recombinant human PCT protein with 6×His tag at N-terminal.
Background:
Procalcitonin (PCT) is a peptide precursor of the hormone calcitonin, the latter being involved with calcium homeostasis. It is composed of 116 amino acids and is produced by parafollicular cells (C cells) of the thyroid and by the neuroendocrine cells of the lung and the intestine. The level of procalcitonin in the blood stream of healthy individuals is below the limit of detection (10 pg/mL) of clinical assays. Its level rises in a response to a proinflammatory stimulus, especially of bacterial origin. Measurement of PCT concentrations during multiple organ dysfunction syndrome provides more information about the severity and the course of the disease than that of CRP. It can be used as a marker of severe sepsis caused by bacteria and generally grades well with the degree of sepsis, although levels of procalcitonin in the blood are very low. PCT has the greatest sensitivity (85%) and specificity (91%) for differentiating patients with systemic inflammatory response syndrome (SIRS) from those with sepsis, when compared with IL-2, IL-6, IL-8, CRP and TNF-alpha.
Purity: >95% by SDS-PAGE
Storage buffer: Lyophilized from 0.01 M PBS (pH7.4) with 2% BSA and 0.03% Proclin 300.
Storage and Expiration:
Ship at 4℃. Upon receipt, aliquot and store at -20℃ or -80℃ for long term. Avoid repeated freeze and thaw cycles.
