Expedeon has introduced five new Alexa Fluor labels to its range of Lightning-Link antibody labelling kits, expanding the range of labels and offering customers increased choice and flexibility for common fluorescence detection-based applications.
The use of secondary antibodies in fluorescence imaging applications is commonly associated with issues such as high background fluorescence and non-specific binding. The combination of Alexa Fluor labels with Lightning-Link technology overcomes these problems, by enabling easy, direct conjugation of the label to primary antibodies in less than 20 minutes.
The Lightning-Link protocol is free of separation steps, saving researchers time and precious materials. The introduction of five new dyes to the range follows the successful launch of the Alexa Fluor 488 kit in 2017. The new Alexa dyes include 647, 700, 555, 568, and 694.
