產品簡介：ICG-NHS酯是一種NHS酯標記胺反應基團的產物。由于它對一級胺（-NH2）具有特異性的反應，能在短時間內標記含胺（-NH2）的蛋白質、抗體和胺修飾的寡核苷酸。

Because ICG effectively absorbs near infrared wavelength that is about 800nm and its absorption ratio for wavelength of visible light range is low, noises caused by Autofluorescence is low.

ICG NHS ester is a product that has the most representative NHS ester reactive group for labeling amine. Because it rapidly and high-specifically reacts to Primary amine (-NH2), it can label Protein containing amine (-NH2), Antibody and Amine-modified Oligonucleotide in a short time period.

ICG NHS ester的NHS可以和蛋白、多肽或抗體上面的NH2發生反應鏈接到一起。

ICG-maleimide的馬來酰亞胺可以和蛋白、多肽、小分子或抗體上的SH巰基反應連接。

ICG-Amine的NH2可以和蛋白、多肽小分子上面的NHS反應連接起來。

ICG和PEG鏈接可在體內長循環。
