Product News: Abcam’s New Alexa Fluor Secondary Antibodies Provide Increased Selection for Multi-Color Staining

04 Nov 2013

Abcam Plc., a leading provider of protein research tools and services, announced today that it has added new Alexa Fluor® 405/568/750 conjugated secondary antibodies to its existing Alexa Fluor® 488/555/594/647 conjugates. Extensively tested in Abcam’s labs, the Alexa Fluor range guarantees bright staining and low background. The different color variants were selected to provide an increased selection for multi-color staining.

The Alexa Fluor portfolio comprises antibodies raised against mouse/rabbit/rat/chicken/goat/sheep/guinea-pig IgG and against mouse/rabbit IgM. It also includes a large selection of pre-adsorbed/cross-adsorbed and F(ab’)2 fragment secondaries to ensure low species cross-reactivity. A dilution range of 1/200 -1/1000 in IF/ICC allows for at least 250 stainings* per product to improve cost efficiency.

Judith Langenick, Product Manager, Secondary Antibodies, commented: “The Alexa range expansion adds a blue emitting fluorophore, Alexa Fluor® 405, and a near IR dye, Alexa Fluor® 750. The addition of Alexa Fluor® 568 is ideal for confocal laser-scanning microscopists, as most of these microscopes have a 561nm laser, which optimally excites the Alexa Fluor® 568 dye. We’re pleased that we can offer our customers more dye variants and enable them to perform multi-color imaging experiments.”

Abcam Alexa Fluor secondaries are ideal for cell biologists and microscopists undertaking multi-color staining from all research backgrounds. The addition of these products complements Abcam’s innovative RabMAb® (rabbit monoclonal antibodies) products and market leading primary antibody range.

Abcam Alexa Fluor secondaries are accompanied with information-rich datasheets, fast delivery, and expert scientific support. They are available globally and can be purchased directly through the Abcam website or through one of Abcam’s authorized distributors.
