631284	IL-2 GoStix™ Plus	50 Tests	USD $1069.00
IL-2 GoStix Plus employ a lateral flow-based detection method and accompanying smartphone application to enable rapid quantification of human IL-2 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-2 present in the sample. The dynamic range and reproducibility of IL-2 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.

Documents Components Image Data Back Timelines associated with commonly used methods for measuring cytokines Timelines associated with commonly used methods for measuring cytokines. GoStix Plus: a lateral flow-based quantitation method. Fast ELISA: measurement using targeted, preformulated ELISA reagents. Standard ELISA: measurement using standard direct or indirect sandwich assay. Bead array: multiparametric measurement by flow cytometry of bead-based, immunocapture of cytokines. Glass array: multianalyte measurement using quantitative, glass-slide multiplex ELISA microarray platform. Assay durations were taken from manufacturers’ protocols. Back GoStix Plus assays provide results similar to ELISA GoStix Plus assays provide results similar to ELISA. Purified, human primary CD3+ T cells were activated for 24 hours using tetrameric antibody complexes to cell-surface ligands CD3, CD28, and CD2. Cell culture supernatant was collected at the time points indicated post-activation and analyzed using both IL-2 GoStix Plus and an ELISA. For the ELISA samples, several dilutions of each sample were run on the assay as suggested by the manufacturer. Back Comparison of T-cell activation methods using IL-2 GoStix Plus and ELISA-based methods Comparison of T-cell activation methods using IL-2 GoStix Plus and ELISA-based methods. Human primary T cells were isolated from peripheral blood (PB) mononuclear cells (MNCs) using negative selection. T cells were subsequently activated with either CD3/CD28-coated beads or CD3/CD28 tetramer complexes following the manufacturers’ protocols. Supernatant samples were collected at the indicated timepoints and assayed for IL-2 protein using IL-2 GoStix Plus or an IL-2 ELISA. Back Cytokine GoStix Plus workflow Cytokine GoStix Plus workflow. Apply 20 µl of sample to a GoStix lateral flow cassette followed by 80 µl of chase buffer. Wait 10 minutes for the test to run, then scan the cassette using the GoStix Plus smartphone app. Back Quantitation of human TH1 cytokines using GoStix Plus lateral flow assays Quantitation of human TH1 cytokines using GoStix Plus lateral flow assays. Purified, human primary CD3+ T cells were activated for 24 hours using tetrameric antibody complexes to cell-surface ligands CD3, CD28, and CD2. Cell culture supernatants were collected at the indicated timepoints post activation and analyzed using IL-2, IFN-γ, and TNF-α GoStix Plus assays and the accompanying GoStix Plus app. Back 631284: IL-2 GoStix Plus
