General description

This Human Interleukin-6 (IL-6) Conferma ELISA kit is used for the quantification of Human IL-6 in serum, plasma, or culture media samples. Human IL-6 is a soluble protein cytokine most commonly associated with the acute inflammatory response to infection or tissue damage.

This is a 96 well format sandwich ELISA which uses our Conferma process to ensure a high degree of lot to lot consistency. The process involves the physiochemical characterization of the ELISAs critical reagents lot to lot, with finished kits being evaluated using a sample library to bridge between lots.

Entrez Gene Summary:
This gene encodes a cytokine that functions in inflammation and the maturation of B cells. In addition, the encoded protein has been shown to be an endogenous pyrogen capable of inducing fever in people with autoimmune diseases or infections.

UniProt Summary:
  • Function: Cytokine with a wide variety of biological functions in immunity, tissue regeneration, and metabolism.
  • Size: 212 amino acids; 23,718 Da
  • Subunit: Component of a hexamer of two molecules each of IL6, IL6R and IL6ST.
  • Subcellular location: Extracellular region or secreted
  • Disease: Rheumatoid arthritis systemic juvenile (RASJ). A IL6 promoter polymorphism is associated with a lifetime risk of development of Kaposi sarcoma in HIV-infected men.
  • Similarity: Belongs to the IL-6 superfamily.


One kit is sufficient to measure 37 samples in duplicate
