Matrices listed below were spiked with certain level of Eng and the recovery rates were calculated by comparing the measured value to the expected amount of Eng in samples.

Linearity
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Eng and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
Eng ELISA Kit allows for the in vitro quantitative determination of Eng concentrations in serum, plasma, tissue homogenates and other biological fluids.
