Matrices listed below were spiked with certain level of TGFβ2 and the recovery rates were calculated by comparing the measured value to the expected amount of TGFβ2 in samples.

Linearity
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of TGFβ2 and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
