The Quantikine Mouse M-CSF Immunoassay is a 4.5 hour solid phase ELISA designed to measure mouse M-CSF levels in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant mouse M-CSF and antibodies raised against the recombinant factor. Results obtained for naturally occurring mouse M-CSF showed linear curves that were parallel to the standard curves obtained using the kit standards. These results indicate that this kit can be used to determine relative mass values for natural mouse M-CSF. Range: 31.20 - 2000 pg/mL. Sensitivity: 5 pg/mL. Time: 4.5 hours
