Etikèt fliyoresan
Koloran fliyoresan yo se zouti enpòtan pou etikèt biomolekil. Dérivés Fluorescein yo ka lajman make sou réactifs ki te itilize nan mikwoskospi fluoresans, flux cytometry, ak deteksyon imunofluorescence. Tipikman, biotin, FITC koloran sa yo ka abitrèman make sou peptides N tèminal oswa C fen. Men, nou rekòmande N End make gen yon pi gwo pousantaj siksè, pi kout tan, ak operasyon pi fasil. Piske peptides yo sòti nan sentèz fen C rive nan fen N, se konsa modifikasyon fen N pral etap final la nan sentèz solid-faz la, elimine nesesite pou etap kouple adisyonèl. Okontrè, si se C End tagging mande pou etap adisyonèl ak pwosesis la pi konplèks.
