产品简介：ICG-NHS酯是一种NHS酯标记胺反应基团的产物。由于它对一级胺（-NH2）具有特异性的反应，能在短时间内标记含胺（-NH2）的蛋白质、抗体和胺修饰的寡核苷酸。

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、多肽或抗体上面的NH2发生反应链接到一起。

ICG-maleimide的马来酰亚胺可以和蛋白、多肽、小分子或抗体上的SH巯基反应连接。

ICG-Amine的NH2可以和蛋白、多肽小分子上面的NHS反应连接起来。

ICG和PEG链接可在体内长循环。
