Descripción

General description

SILu^™ Prot IL-6 is a recombinant, stable isotope-labeled human IL-6 which incorporates [¹³C₆, ¹⁵N₄]-Arginine and ^[13C₆, ¹⁵N₂]-Lysine. Expressed in human 293 cells, it is designed to be used as an internal standard for bioanalysis of IL-6 in mass-spectrometry. SILu^™ Prot IL-6 is a monomer of 183 amino acids, with a molecular weight of ~21 kDa.

Biochem/physiol Actions

IL-6 is an abundant cytokine, which is crucial for leukocyte and endothelial cell activation. IL-6 is one of the major cytokines that are implicated clinically as biomarkers in ACS (Acute Coronary Syndrome). Its pathophysiological contribution to ACS is the induction of acute-phase response. Patients with ACS have increased circulating levels of IL-6 compared with those patients who have stable angina. Among patients with unstable angina, an increase in IL-6 levels that occurred 48 hours after admission compared with the admission value was associated with the combined end point of death, myocardial infarction (MI), or refractory angina. High levels of IL-6 are also related to cardiovascular disease, heart attack, and stroke.
