Tech Info / Data

Induction of Human IFN-Beta by TLR-7/8 Agonist Stimulation of PBMCs
Representative Standard Curves in Various Matrices for PBL's VeriKine-HS Human IFN-Beta TCM ELISA Kit (Catalog No. 41435)

The VeriKine-HS Human IFN-Beta TCM ELISA Kit is designed for accurate quantification of low level human interferon beta in buffers or tissue culture media (TCM) by sandwich ELISA. The lowest concentration of Hu IFN-Beta is 2.34 pg/ml. This kit is not intended for use with human serum or plasma samples due to a significantly elevated risk of false positive results. For complex biological matrices such as plasma, healthy, and disease sera, we recommend our High Sensitivity Human IFN Beta Serum ELISA Kit (Cat. No. 41415-1).

Interferon Beta (IFN-Beta, IFNb) is synthesized and secreted by fibroblasts and many other cell types in response to varied stimuli in Toll-like receptor (TLR) dependent and independent mechanisms. Pathogen exposure can result in the activation of transcription factors interferon regulatory factor 3 (IRF3) and NF-kB resulting in IFN-Beta production in a stimuli and cell-dependent manner. Conversely, IFN-Beta aberrant expression may be associated with inflammation and autoimmunity.

Parallelism of Endogenous Samples using PBL's High Sensitivity Human IFN-Beta TCM ELISA (41435)

Parallelism of endogenous samples using PBL's Human IFN Beta TCM ELISA (41435)

Five endogenous samples were tested in duplicate for assay parallelism. Samples were serially diluted in TCM to the 32-fold dilution that lies within the kit's assay range. Percent recoveries are 100 ± 20% of neat value except for the 32nd dilution of Sample 5 (S5) which falls marginally out of the assay's LLOQ (2.34 pg/ml).
