Matrices listed below were spiked with certain level of TNFSF13/APRIL and the recovery rates were calculated by comparing the measured value to the expected amount of TNFSF13/APRIL in samples.

Linearity
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of TNFSF13/APRIL and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
