I used rat serum for the analysis. The assay procedure was simple and reagents quantities were perfect. The assay was easy to use and sensitive, I got the reliable results compare to the from the previous experiments.

I used rat plasma (heparin anti coagulated) and kidney lysate. After determining an appropriate dilution, using two lanes of the plate, went on to determine the concentrations present in our sample. The assay was easy to use and sensitive, corroborating results from other experiments.
