For the quantitative determination of rat granulocyte colony stimulating factor in serum, plasma, cell culture supernates and tissue homogenates. Sensitivity: 7.81pg/ml Detection Range: 31.25-2000pg/ml Specificity: This assay has high sensitivity and excellent specificity for detection of rat G-CSF. No significant cross-reactivity or interference between rat G-CSF and analogues was observed. Assay Principle: This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for G-CSF has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any G-CSF present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for G-CSF is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of G-CSF bound in the initial step. The color development is stopped and the intensity of the color is measured.
