PBL Assay Systems: Featured Products


Human IFN-Alpha ELISAs (All-Subtype)

As multiple IFN-Alpha subtypes are often present in biological samples, the ability to determine the total amount of IFN-Alpha is integral to a full understanding of its role within the immune system. PBL's kits are designed to provide low pg/ml sensitivity all-subtype detection (12 of 12) in various matrices: tissue culture media (TCM) only; normal & autoimmune sera, EDTA plasma and TCM.

Human IFN-Beta ELISAs

Highly sensitive immunoassays (< 3 pg/ml LLOQ) displaying no inhibition of IFN-Beta detection in the presence of excess sIFNAR2 protein, thus measuring "total" IFN-Beta. PBL's kits are developed to measure IFN-Beta in various matrices: tissue culture media (TCM) only; healthy and autoimmune disease sera*, plasma and TCM. *Independently validated for measurement of IFN-Beta levels in autoimmune disease sera
