3-HYDROXY-4-(5-NITROPYRIDYLAZO)PROPYLANI CAS:143205-66-7

Waa baaritaan fluorescent ah oo ka kooban koox nitrobenzoxadiazole (NBD), oo muujisa astaamo fluorescence oo xooggan. Kooxda aldehyde waxay u oggolaanaysaa calaamadaynta gaarka ah iyo ogaanshaha molecules-ka noolaha sida borotiinnada, asiidhyada nucleic-ga, iyo dufanka.

NBD-aldehyde waxaa badanaa loo isticmaalaa midab falgal ah oo lagu sameeyo baaritaannada lagu ogaanayo laguna cabbirayo falcelinta isku-xidhka borotiinka ama peptide, wax ka beddelka borotiinka, iyo isdhexgalka borotiinka-borotiinka. Waxay calaamadayn kartaa kooxaha amino ee bilaashka ah ee borotiinnada ama peptides, iyadoo samaynaysa isku-xidhka covalent ee deggan. Tani waxay ka dhigaysaa mid waxtar u leh codsiyada sida immunocytochemistry, immunohistochemistry, iyo western blotting.

Iftiinka NBD-aldehyde waxaa lagu kicin karaa iftiinka ultraviolet ama buluugga ah, waxayna soo saartaa iftiinka cagaaran. Sifadani waxay suurtogal ka dhigaysaa aragtida iyo cabbirka unugyada noolaha ee calaamadaysan iyadoo la adeegsanayo mikroskoobka fluorescence ama farsamooyinka spectroscopy.
