  • ELISA (Enzyme-Linked Immunosorbent Assay) – Ultra Sensitive Detector of Proteins

    ELISA is a quantitative and ultra-sensitive plate-based assay designed to detect and quantify substances such as antibodies, hormones, proteins (e.g. cytokines) and peptides, receptors on cells as well as small molecule drugs. The ELISA has been a workhorse method since the 1970s. The method has a sensitivity/detection level of approaching 1pg/ml for a particular protein, even in a….

  • Flow Cytometry of T and B Cells and NK Cells

    Flow cytometry can differentiate different cell populations based on cell size by forward and side scatter measurements. Specific cell types are also be identified by staining with fluorescent-tagged antibodies that recognize specific cellular markers. Readouts can be cell population analyses, proliferation, apoptosis, death/cell cycle analysis, intracellular or surface proteins, cytokine production, and binding studies. Analysis….
