Takara IL-6 GoStix

IL-6 GoStix Plus employ a lateral flow-based detection method and accompanying smartphone application to enable rapid quantification of human IL-6 from cell culture supernatant or serum samples in only 10 minutes. Simply apply 20 µl of sample and 80 µl of chase buffer to a GoStix cassette, wait 10 minutes for test and control bands on the cassette to develop, and then scan the cassette using a mobile device running the GoStix Plus app to quantify the amount of IL-6 present in the sample. The dynamic range and reproducibility of IL-6 GoStix Plus are comparable to the performance of an ELISA, such that users can expect to obtain similar results in a fraction of the time.

Assay durations were taken from manufacturers’ protocols.

IL-6 GoStix Plus provide results similar to ELISA. Purified, human peripheral blood mononuclear cells (PBMCs) from two healthy donors were activated with phytohemagglutinin (PHA). Cell culture supernatant was collected at the time points indicated post-activation and replicate samples were analyzed using both IL-6 GoStix Plus and ELISA. For the ELISA samples, several dilutions of each sample were run on the assay as suggested by the manufacturer.
