Lightning-Link® is an innovative technology that enables direct labeling of proteins, peptides or other biomolecules for use in R&D applications, drug discovery and the development of diagnostic kits.

The easy-to-use, one step procedure allows researchers to covalently label biomolecules with only 30 seconds hands on time. The researcher simply pipettes the biomolecule into a vial of lyophilized mixture containing the label of interest and incubates. Despite its apparent simplicity, the Lightning-Link® process is sophisticated and generates conjugates with performance characteristics identical to, or better than, those prepared with laborious multistep conjugation procedures.

The Lightning-Link® range currently consists of 50+ kits including enzymes, biotin, streptavidin and fluorochromes covering the spectrum from UV to far infrared. Lightning-Link® conjugates are used in a large number of scientific applications including Western Blotting, immunofluorescence, immunohistochemistry, flow cytometry, ELISA and FRET.

Alkaline Phosphatase Label

Alkaline phosphatase (AP) is a hydrolyase enzyme that is frequently conjugated to antibodies for use in immunoassays. PNPP is a popular colorimetric substrate for AP; the product of the reaction, p-nitrophenol, can be read at 405nM. Fluorogenic substrates (e.g. 4-methylumbelliferyl phosphate; MUP) may also be employed.
