“These powerful dyes can allow for a much greater separation of positive and negative, helping to accelerate answers and shed more light on crucial laboratory tests,” said Dr. Mario Koksch, Vice President and General Manager of the Flow Cytometry business unit at Beckman Coulter Life Sciences. “Our SuperNova polymer dye conjugates can generate significantly less non-specific staining to help deliver more accuracy in results. These dyes can help eliminate false positives while reducing potentially expensive re-testing due to fuzzy results.”
SuperNova dyes are a novel portfolio of polymer dyes that produce increased light when excited by a violet laser for their respective channel, allowing for a strong distinction between positive and negative populations for dimly expressed markers. For flow cytometry staining, SuperNova conjugated antibodies have a unique brightness. Beckman Coulter Life Sciences’ exclusive, proprietary formulation uses special additives to reduce non-specific staining for greater confidence and clarity.
“We have tested SuperNova v428 conjugated antibodies on about 50 whole blood samples from healthy donors,” said Maxime Moulard, Scientific Director at BioCytex, a Biotech company specializing in the standardization of flow cytometry assays. “The outstanding performances, including the staining index, are remarkable for SuperNova v428 conjugated antibodies. In addition, the brightness and non-specific staining are significantly improved compared to other conjugated antibodies we are used to working with.”
Light can be absorbed by polymers made of various monomers and then re-emitted at a longer wavelength. Core polymers can be used to make tandems, and both core and tandem polymers can be conjugated to antibodies. Beckman Coulter Life Sciences has created a patented technology for producing tandems with improved stability and optimum FRET. Users of flow cytometry are pleased with the results, citing a significant improvement in clarity and a 57 percent higher staining index than a competitor’s product.
The maximum emission peak of SuperNova v428 is 428 nm, and it can be observed on a flow cytometer with a 450/50 nm bandpass filter or equivalent. New conjugated antibodies will be launched regularly, and the first RUO and ASR catalog products produced under current Good Manufacturing Practices are now available. The SuperNova v605 and SuperNova v786 tandem polymer dyes are also available for custom conjugation. They are best detected using the flow cytometer’s 610/20 and 780/60 nm bandpass filters, which have emission peaks at 605 and 786 nm.
