Profile: Biosearch Technologies, Inc. is an ISO 9001:2000 certified company which designs and manufactures fluorogenic probes & reagents for DNA synthesis. We offer amidites, columns & CPG supports for DNA/RNA synthesis, DNA purification columns, esters & carboxylic acids for protein & peptide labeling, supports for peptide synthesis, and immunochemicals. We also deliver custom synthesis services for fluorogenic probes & primers for real-time qPCR, unmodified & single-labeled oligonucleotide synthesis, oligos for SNP genotyping, oligos in plates, and microarray oligos. Our new group of proprietary dyes for fluorescence quenching, black hole quencher® (BHQ® dyes) allows for the designing of simpler, more effective probes. Additionally, BHQ probes facilitate multiplexing of 5 or more probes in a single assay.
