Ole su'esu'ega fou ole chromatography vai maualuga mo glycosyltransferases e fa'avae ile fa'atupuina ile anthranilic acid ma le su'esu'eina ole fluorescence.
O suʻesuʻega na faia e faʻaaoga ai le kemisi faʻailoga tulaga ese o le 2-aminobenzoic acid (2AA; anthranilic acid, AA) mo le fuaina o gaioiga o le β1-4 galactosyltransferase (GalT-1) ma le α2-6 sialyltransferase (ST-6) e ala i le maualuga o le sua. chromatography (HPLC) faʻatasi ai ma le suʻesuʻeina o le fluorescence (Anumula KR. 2006. Faʻalauiloa i auala faʻasolosolo faʻasolosolo mo le maualuga o le suʻesuʻeina o le chromatographic sua o le glycoprotein carbohydrates. Anal Biochem. 350: 1-23).N-Acetylglucosamine (GlcNAc) ma N-acetyllactosamine na faʻaaogaina e avea ma tagata e taliaina ma uridine diphosphate (UDP) -galactose ma cytidine monophosphate (CMP) -N-acetylneuraminic acid (NANA) e fai ma foaʻi mo GalT-1 ma ST-6, i le faasologa.O oloa Enzymatic na fa'ailogaina i totonu ma le AA ma sa vavae'ese mai mea'ai i luga o le TSKgel Amide 80 koluma e fa'aaoga ai tulaga masani.O iunite o le enzyme na fa'amauina mai vaega pito i luga e ala i le fa'atusatusaina ma tulaga fa'atupu fa'atasi Gal-β1-4GlcNAc ma NANA-α2-6 Gal-β1-4GlcNAc.Linearity (taimi ma enzyme concentration), saʻo (intra-ma interassay) ma reproducibility mo suʻega na faʻavaeina.O suʻesuʻega na maua e aoga i le mataʻituina o gaioiga enzyme i le taimi o le tuʻuesea ma le faʻamamaina.O su'ega sa matua ma'ale'ale ma fa'atino tutusa pe sili atu fo'i nai lo fua fa'atatau masani fa'atatau o le suka.E mafai fo'i ona fa'aoga le fa'asologa o su'esu'ega mo le fuaina o le gaioiga o isi fa'aliliuga, pe a fa'apea o lo'o i ai i tagata e taliaina le carbohydrate se fa'ai'uga fa'aitiitia mo le fa'ailoga.O se suʻesuʻega mo tagata e taliaina glycoprotein na atiaʻe e faʻaaoga ai le IgG.O se auala puupuu HPLC profiling na atiina ae mo le tuueseeseina o IgG glycans (bintennary G0, G1, G2, mono- ma disiaylated), lea na faafaigofie ai le fuafuaina o gaoioiga GalT-1 ma ST-6 i se faiga vave.E le gata i lea, o lenei metotia faʻamatalaga e tatau ona faʻamaonia aoga mo le mataʻituina o suiga ile IgG glycans ile falemaʻi.
