This kit is shipped at room temperature. Upon receiving, please store the Reagent and Standard in the refrigerator (4°C) and the Urease at -20°C to 4°C. For long term storage, keep the standard at -20°C.
Yes, there is a standard curve in the datasheet; we include this to show the linear detection range of the kit for quantifying urea. Due to interference, an internal standard must be run for most samples. The datasheet has detailed information on how to perform this and calculate urea concentration from it.
If you wish to construct a standard curve, you may dilute the urea standard in dH2O and follow the instructions from question 4 below.
Please refer to our DUR2-100 Urine Detection Protocol.
Yes, unused reagents can be stored according to the assay protocol.
This assay is pH dependent; therefore, temperature can affect the results. Be sure to equilibrate all components to room temperature before each assay.
