The Quantikine Porcine IL-1 beta Immunoassay is a 4.5 hour solid phase ELISA designed to measure porcine IL-1 beta in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant mature porcine IL-1 beta and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant porcine IL-1 beta. Results obtained using natural porcine IL-1 beta show dose response curves that are parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural porcine IL-1 beta. Range: 39.10 - 2500 pg/mL. Sensitivity: 13.6 pg/mL. Time: 4.5 hours
