The Quantikine Mouse/Rat Flt-3 Ligand Immunoassay is a 4.5 hour solid phase ELISA designed to measure mouse or rat Flt-3 Ligand levels in cell culture supernates and serum. It contains NS0-expressed recombinant mouse Flt-3 Ligand and antibodies raised against the recombinant protein. Results obtained for naturally occurring mouse or rat Flt-3 Ligand 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 of natural mouse/rat Flt-3 Ligand. Range: 31.20 - 2000 pg/mL. Sensitivity: 5 pg/mL. Time: 4.5 hours
