Background: IL-37/IL-1F7

Human interleukin 37, also named IL-1F7, FIL1 zeta, IL-1H4, and IL-1rp1, belongs to the IL-1 cytokine family. With the exception of IL-18 that maps to human chromosome 11, all IL-1 family members map to the same cluster on human chromosome 2. Mouse IL-37 has not been reported, but human IL-37 is active on mouse cells. Five isoforms (IL-37a through e) are generated through alternative exon usage and have distinct expression profiles. Like IL-1 alpha, IL-1 beta and IL-18, all of the IL-37 variants lack a typical signal peptide.

  1. Which isoforms of IL-37/IL-1F7 does this DuoSet ELISA detect?

    • This assay is calibrated against the IL-37a isoform. It is possible that the assay also detects additional isoforms, however, R&D Systems has not performed this characterization.

Human IL-37/IL-1F7 DuoSet ELISA

Human IL-37/IL-1F7 DuoSet ELISA
By Jonatan Dereke on 02/16/2017
Sample Tested: EDTA Plasma

After optimization we ran human EDTA-plasma samples at a 1:10. Due to huge variations in IL-37/IL-1F7 levels we added another standard at 4000pg/ml to the analysis. The high variations also makes it necessary to further dilute a number of patient samples in order to get values within the standard range.
