AlphaLISA® technology Basics

From small molecules to live cells, the assay that measures it all​

AlphaLISA Assay Principle​

AlphaLISA is a bead-based, no-wash luminescent technology. When Alpha Donor and Acceptor beads are brought together through binding to the target, a cascade of chemical reactions is set in motion, creating an amplified signal. These versatile beads are conjugated with various biomolecules that enable the detection of unique biological events, offering maximum flexibility.

How AlphaLISA technology assays work​

An AlphaLISA assay is easy to run, and requires few steps:​

First add your analyte or sample to your microplate, then add acceptor beads and antibodies. Incubate 1 hour. Add donor beads and incubate 30-60 minutes. The interaction between bead-bound molecules and analyte brings the bead into proximity. Excite the donor beads with red light. A singlet oxygen is generated by the donor beads, which excites the acceptor beads and will emit light proportional to the level of interaction.

How AlphaLISA advances your science

Ease of use with no wash and no separation steps, fast results in 3 hours for most applications, high sensitivity to detect down to femtogram levels of targets, large dynamic range up to 4-5 logs, and a compatibility with many sample types definitely make Alpha an optimal choice when it comes to moving your research a step forward!​​
