The Quantikine Mouse G-CSF Immunoassay is a 4.5 hour solid phase ELISA designed to measure mouse G-CSF in cell culture supernates and serum. It contains E. coli-expressed recombinant mouse G-CSF and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant mouse G-CSF accurately. Results obtained using natural mouse G-CSF showed dose-response curves that were parallel to the standard curves obtained using the recombinant Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural mouse G-CSF. Range: 14.10 - 900 pg/mL. Sensitivity: 5 pg/mL. Time: 4.5 hours
