Antibodies Incorporated, Davis, Calif., announced today that they are immediately commencing shipment of quantum dot-based secondary antibody, Streptavidin, Protein A and Protein G conjugates as well as launching a custom quantum dot conjugation service. Using EviTags® from Evident Technologies, Inc., these conjugates will be made ready-to-use for researchers in biology, life-sciences, drug discovery, disease diagnostics, proteomics, and genomics.

Traditionally, fluorescent organic dye conjugates serve as the workhorses for biotechnology research and diagnostics. These conjugates make it possible to locate, quantify, and identify proteins and genes that are the key to furthering understanding in many life science applications.

“We are excited by the performance of EviTags and are pleased to offer these next-generation quantum dot based conjugates to our university research and biotech industry customers,” said Richard Krogsrud, Ph.D., CEO of Antibodies. “Evident Technologies’ new quantum dot technology, combined with our 42 years of experience in secondary and custom polyclonal antibodies, makes for some exciting new products.”

“Our EviTags attached to antibodies offer distinct advantages over traditional organic fluorophores, including greatly improved photostability, color multiplexing, and single-source excitation,” said Clinton Ballinger, Ph.D., CEO of Evident Technologies, based in Troy, N.Y. “All of these attributes make quantum dots a breakthrough technology for biological applications.”

Michael DeVincenzo, Esq., Evident Technologies’ Internal Intellectual Property Counsel, commented: “Quantum dots were discovered over 20 years ago, and researchers from around the world have been developing the technology ever since. Finally, the technology has been brought to commercialization, and we are proud to offer new products for the world’s researchers. The future promises to be exciting and we expect these products to enable numerous unforeseen biological applications.”

Quantum dot conjugates are the next stage in the evolution of biotechnology research tools and offer improved photostability, single source optical excitation, and a multiplicity of tunable narrow-band emission colors that span the visible and infrared spectrum. With these attributes, researchers can perform more tests, see more details in cells and have freedom to perform long-term imaging.
