Human SLPI Quantikine ELISA Kit Summary

The Quantikine Human SLPI Immunoassay is a 4.5 hour solid phase ELISA designed to measure SLPI in cell culture supernates, serum, plasma, and urine. It contains E. coli-expressed recombinant human SLPI and antibodies raised against the recombinant factor. The kit has been shown to accurately quantitate recombinant human SLPI. Results obtained using natural human SLPI showed linear c...urves that were parallel to the curves obtained using the recombinant kit standards. These results indicate that this kit can be used to determine relative mass values for natural human SLPI.
