荧光标记纳米金颗粒(CY3/CY5/CY7/FITC-高分子PEG-Gold Nanoparticles,Au)
【荧光标记图片微米金颗料】:我平台能否提拱2种表现形式的荧光素标记图片納米级金颗粒物新产品,有一种是凭借拿高氧分子PEG在后面衔接,PEG两边接荧光素除此之外下端连納米级金,另有一种是納米级金凭借共价键方法随时和荧光素衔接。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.
