Click2ContactBeckman Coulter Life Sciences, a Danaher company, has launched its IR820 and IR870 infrared dye antibody conjugates. The IR820 and IR870 reagents are claimed to be the industry’s first directly conjugated antibodies for infrared excitation. Current flow cytometry fluorochrome conjugates do not cover the infrared range. By this spectral colocalisation, typically bright lineage markers may compromise resolution and sensitive detection of their dimmer co-expressed companions. The infrared dye conjugates, with their low-noise design, remove complexities and allow for a more flexible antibody panel design.
