产品描述：

ICG is a NIR fluorescent substance which obtain license for clinical uses from US FDA(Food and Drug administration), along with Methylene Blue. It is used in Ophthalmologic angiography, liver function tests, solid tumor detection in surgical operation and angiography.

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是一种近红外荧光物质，与亚甲基蓝一起获得美国食品和**管理局(FDA)的临床使用许可。它用于眼科血管造影、肝功能检测、外科手术中的实体瘤检测和血管造影。

由于ICG能**吸收800nm左右的近红外波长，且对可见光波长的吸收率较低，因此自发荧光产生的噪声较低。

ICG NHS酯是一种具有最具代表性的NHS酯反应基团的产品，用于标记胺。由于它对伯胺(-NH2)反应迅速且特异性高，因此可以在短时间内标记含胺(-NH2)、抗体和胺修饰寡核苷酸的蛋白质。
