The BioPlex 200 System is a multiplex bead analysis system powered by xMAP technology that allows the simultaneous analysis of up to 100 different molecules (proteins, peptides or nucleic acids) in a single micro-plate well. The system is more powerful and rapid than the FACS array, more than 1800 assay points per well can be read in 30 minutes. As measurements are made in the 96 well plate format, this increases the amount of information from rare or volume-limited samples. Applications include assays protein expression profiling including cytokine, chemokine, endocrine and growth factors; metabolic, cancer and cardiac markers; cell signalling; genotyping and gene expression profiling and transcription factors/nuclear receptors. Commercially available and customised kits are available from several suppliers.
