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 Azide is labeled on Aldehyde or Ketone, and it is used for fluorescence labeling of small molecule compounds such as hormone and saccharide. To label ICG Azide on polysaccharide or glycoprotein, oxidation process that oxidizes saccharide to Aldehyde is required. In general, it utilizes Sodium periodate-mediate oxidation method of vicinal diol. Excitation / Emission (nm): 785 / 821 nm. Extinction coefficient: 240,000 cm-1M-1.
