          Product Summary

          The Quantikine Human SCF Immunoassay is a 4.5 hour solid phase ELISA designed to measure SCF levels in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human soluble SCF (KL-1 variant) and antibodies raised against this recombinant factor. Results obtained for naturally occurring human SCF samples showed linear curves that were 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 human SCF.

          Precision

          Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision
          Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision

          Recovery

          The recovery of SCF spiked to levels throughout the range of the assay in various matrices was evaluated.

          Sample Type Average % Recovery Range %
          Cell Culture Media (n=2) 85 75-93
          Citrate Plasma (n=8) 94 84-112
          EDTA Plasma (n=8) 98 82-110
          Heparin Plasma (n=8) 99 88-116
          Serum (n=8) 99 87-111

          Linearity

          To assess the linearity of the assay, the following biological samples were diluted with the appropriate Calibrator Diluent and then assayed. The cell culture media was spiked with exogenous SCF.
