Recombinant human interleukin-6 (with HSA)

Recombinant human interleukin 6 (IL-6) is a single, nonglycosylated, polypeptide chain containing 185 amino acids. IL-6 has a molecular weight of 21kDa. IL-6 is produced in Escherichia coli.

IL-6 is used to induce its cognate signalling pathway in HEK-Blue™ IL-6.

Detection by SDS-PAGE

SDS PAGE of the recombinant human (h)IL-6 protein. 1.5 μg of hIL-6 was loaded on a 12% Mini-PROTEAN® TGX Stain-Free™ Precast Gel (Bio-Rad) stained with Coomassie. Detection was performed as per the manufacturer’s instructions. A band was detected at ~21 kDa

Dose-response in HEK-Blue™ IL-6 cells to recombinant IL-6 cytokine
Dose-response in HEK-Blue™ IL-6 cells to recombinant IL-6 cytokine

Dose-response in HEK-Blue™ IL-6 cells to recombinant IL-6 cytokine. Cells were stimulated with increasing concentrations of recombinant human IL-6. After overnight incubation, the NF-κB-induced SEAP activity was determined using QUANTI-Blue™, a SEAP detection reagent. Data are shown as optical density (OD) at 650 nm (mean ± SEM).
