Abcam Introduces Alexa Fluor Secondary Antibodies

  • New range offers increased choice for multi-colour staining
Alexa® product launchCambridge, UK, November 04 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.

“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-colour imaging experiments”.

– Judith Langenick, Product Manager, Secondary Antibodies
