  • RelevanceProcalcitonin (PCT) is a 116 amino acid residue peptide with molecular weight of about 13 kDa. PCT itself has no known hormonal activity. PCT belongs to a group of related proteins including calcitonin gene-related peptides I and II, amylin, adrenomodulin and calcitonin (CAPA peptide family). PCT, like other peptides of CAPA family, appears from the common precursor pre-procalcitonin consisting of 141 amino acids by removal of 25 amino acids from the N-terminus. PCT undergoes successive cleavages to form three molecules: N-terminal fragment (55 a.a.), calcitonin (32 a.a.) and katacalcin (21 a.a.). Under normal metabolic conditions, PCT is only present in the C cells of the thyroid gland. In bacterial infection and sepsis, however, intact PCT is found in the blood and, more importantly, its level is related to the severity of bacterial sepsis. Today, PCT is considered to be one of the earliest and most specific markers of sepsis.

Thank you for contacting us.
The shipment of the package should not have affected the activity of the antibody. Lyophilised protein is stable at room temperature for days. I am unsure as to why you have seen and increase in signal in this case, bu...

Thank you for your enquiry. I appreciate your patience, it has regrettably taken some time to confirm the information for you.

I can let you know that these three proteins do not have a tag of any kind.

I hope this will be helpful...
