What functional groups do I need on my protein?

Lightning-Link requires amine groups on the molecule to be labeled. Most proteins have lysine and/or alpha-amino groups. All antibodies will have multiple amine functions.

Do I need to purify the conjugate?

No. The chemicals used in Lightning-Link are deactivated by the quencher, and the by-products are benign and do not need to be removed.

Can non-antibody molecules be labeled?

Yes. While labeling of antibodies is a major application, the only requirement is that the protein to be labeled has amine functionality.

Product Summary for Lightning-Link (R) Fluorescein Antibody Labeling Kit

Lightning-Link antibody labeling kits enable the direct labeling of antibodies, proteins, peptides or other biomolecules for use in R&D applications, drug discovery and the development of diagnostic kits (See protocol for further information).

Our Fluorescein antibody labeling kit enables the direct conjugation of Fluorescein to any biomolecule with an available amine group. The researcher simply pipettes the antibody or other biomolecule into the vial of Lightning-Link Fluorescein and incubates for 3 hours.

Application Notes

By circumventing the desalting or dialysis steps that commonly interrupt traditional antibody conjugation procedures, LightningLink technology can be used to label both small (e.g. 10 ug) and large quantities of primary antibodies with ease. Batch-to-batch variation upon scale up is minimal as the process is so simple, and recoveries are always 100%. This kit is supplied with 3 vials, each suitable for labeling up to 200 ug of antibody.

Background: Lightning-Link (R) Fluorescein

Easy FITC labeling of your antibody with 30 seconds hands-on time. Fluorescein is a fluorophore widely used in biological analysis, with a pH dependent absorption and emission spectrum. In water it shows an absorption maximum at 494 nm and an emission maximum of 521 nm. The Lightning-Link conjugation system represents a quantum leap forward in conjugation technology. It allows you to make antibody conjugates with minimal hands-on time - less than 30 seconds. Lightning-Link simplifies immunoassay techniques, such as western blotting, ELISA and immunohistochemistry, by eliminating secondary reagents and cutting the number of incubation and wash steps. Despite its simplicity, Lightning-Link is a very sophisticated conjugation system in which the antibody is directionally coupled to the label (and not to itself) in a controlled fashion, creating high quality conjugates. As the procedure is not interrupted by desalting steps, trial conjugates can be prepared with microgram quantities of protein and then scaled up with ease. Lightning-Link eliminates problems associated with scale up; hands-on time is essentially independent of process scale. Consistency from batch to batch is easy to achieve, and recoveries approach 100%.
