AlphaLISA Binding Kits

The interactions and binding of proteins are implicated in a large number of biological processes. The need for an efficient, highly sensitive assay to study large protein interactions is increasingly important. Alpha Technology is a highly flexible, homogeneous, no-wash assay ideal for the measurement of protein interactions and complexes as large as 200 nm in size. A bead-based proximity assay, Alpha Technology offers the possibility to assay many biological targets, including enzymes, receptor-ligand interactions, low affinity interactions, second messenger levels, DNA, RNA, proteins, peptides, sugars and small molecules.

Features:

• No-wash steps, no separation steps
• Ease-of-use: few addition steps, fast assay development
• Broad range of affinities: detect strong or weak interactions, from pM to mM affinity
• Distance: measure very large protein or antibody complexes – spanning up to 200 nm or more
• High avidity: multiple binding sites on each bead enables use of nanomolar concentrations of antibodies or proteins, as well as use of low affinity binders
