Description
ICG Labeling Kit – NH2 is used primarily for the preparation of ICG (Iindocyanin green)-labeled antibody for near-infrared fluorescence imaging. ICG offers two remarkable properties:
1) ICG has a strong near-infrared fluorescence even after a few days under physiological conditions. The excitation and emission wavelength of the ICG-labeled proteins are 774 nm and 805 nm, respectively.
2) ICG has been used in clinical fields such as a hepatic deficiency testing. Therefore, ICG and ICG conjugates are materials suitable for in vivo imaging.
This kit contains all required compornents required for labeling, including storage buffer for conjugates. The labeling process is simple:. Add NH2-reactive ICG to protein solution on a filter membrane, and incubate at 37ºC, for 10 minutes. A filtration tube can remove excess ICG molecules.

Precaution
♦ If the IgG solution contains other proteins with molecular weight greater than 10,000, such as serum albumin or gelatin, purify the IgG solution before labeling fluorescein with this kit. Commercially available antibody may contain BSA or gelatin as a stabilizer.
