IL-2 GoStix Plus
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.
Overview
- Rapidly quantify human cytokines from cell culture supernatant or serum samples using a simple, 10-minute assay that performs comparably to an ELISA
- Obtain accurate, reproducible results without extensive technical expertise or expensive equipment
- Conserve resources by identifying the most promising candidates for further analysis
- Accelerate your research by obtaining results immediately rather than waiting days or weeks to accumulate enough samples for processing in high-throughput formats
Applications
- Quantification of human cytokines from cell culture supernatant or serum samples
- Screening or monitoring of immune cell populations
- Analysis of immune responses
- Determination of suitable dilution factors for subsequent analyses
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.
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.
Comparison of T-cell activation methods using IFN-γ GoStix Plus and ELISA-based methods.
Comparison of T-cell activation methods using IFN-γ 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, CD3/CD28 tetramer complexes, or PHA (10 μg/ml). Supernatant samples were collected at the indicated timepoints and assayed for IFN-γ protein using IFN-γ GoStix Plus or an IFN-γ ELISA. Assay results were converted into IU/ml values using NIBSC reference standard 82/587.
