Multiplexed ELISA Arrays Detect Biomarkers

Multiplexed ELISA Arrays, for quantitative, simultaneous measurement of multiple biomarkers, utilize a pre-spotted plate with up to 25 different capture antibodies per well. A variety of arrays are offered, for the quantification of numerous markers, including rat cytokines and mouse cytokines, chemokines and immunoglobulins, as well as human cytokines, chemokines and adipokines. Human angiogenic, hematopoetic, tumor and hormone markers can also be quantified. Following a simple ELISA protocol, the chemiluminescent signal is captured with a commercially available cooled CCD imaging system. After image analysis, the intensity of the spots for each unknown sample is compared with standard curves and the exact values of each biomarker (μg-pg/ml) are calculated. If no imaging system is available or if preferred, Quansys offers a sample testing service for any of the markers in its arrays.
