IL2 and cancer: Minimum detectable IL-2 concentration with our system is approximately 50 times higher than the commercial ELISA kits35, yet this is partially due to the maturity in cytokine detection with ELISA36, while the detection limit of ELISA for other proteins, such as cancer markers19, could be much higher, where our system becomes favourable, not only in terms of sensitivity, but also for the time required to do the measurement, where it is possible to complete the process within half an hour, while it takes more than four hours with a standard ELISA measurement.
