HDB provides direct expression and comparison analysis of biomarkers using multi-color fluorescence flow cytometry. Our BD FACSCalibur is equipped with dual lasers which allow exploring cell type markers and activation markers in one assay on the single cell level with high sensitivity, minimal compensation and maximum flexibility in fluorochrome selection. Up to four different biomarkers, intracellular markers or cell surface markers can be analyzed in parallel. It's also equipped with HTS sampler compatible for 96- and 384-well
