Single molecule array (Simoa) testing is a protein detection technique that is orders of magnitude more sensitive than standard sandwich based immunoassay techniques. Traditional ELISA measurements are limited to pg/ml levels of detection. The RayBio Ultrasensitive Simoa Testing Services can achieve sensitivity as low as femtogram (fg/ml) levels, allowing the quantification of biomarkers at concentrations previously difficult…
