Matrices listed below were spiked with certain level of IL-35 and the recovery rates were calculated by comparing the measured value to the expected amount of IL-35 in samples.

Linearity
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of IL-35 and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
