荧光标记纳米金颗粒(CY3/CY5/CY7/FITC-高分子PEG-Gold Nanoparticles,Au)
荧光标记纳米金颗粒(CY3/CY5/CY7/FITC-高分子PEG-Gold Nanoparticles,Au)
【荧光标出納米金顆粒】:我司就可以保证2种方法的荧光素标上微米金颗粒物產品,的一种是可以顺利通过夺氧分子PEG在中央接,PEG一遍接荧光素最后一边连微米金,另的一种都是微米金可以顺利通过共价键方试直接的和荧光素接。Xi an qiyuebio fluorescent labeled gold nanoparticles were made from monodispersed gold nanoparticles with narrow size distribution (<15%). Fluorescent molecules, from green to near infrared region, including fluorescein (FITC), rhodamine, Cy3, Cy5 or Alexa fluor dyes, were convalently attached to the gold surface. These fluorescently labeled gold nanoparticles are stable in aqueous buffer and is useful for generating various gold nanoparticle probes to detect various biomolecules in SEM, TEM, light microscopy and blotting.
