Ko te whakamatautau chromatography wai mahi nui hou mo nga glycosyltransferases i runga i te whakamaaramatanga me te waikawa anthranilic me te kitenga o te fluorescence.
I whakawhanakehia nga whakamatautau ma te whakamahi i te matū tapanga ahurei o te waikawa 2-aminobenzoic (2AA; waikawa anthranilic, AA) mo te ine i nga mahi o te β1-4 galactosyltransferase (GalT-1) me te α2-6 sialyltransferase (ST-6) na te wai mahi nui. chromatography (HPLC) with fluorescence detection (Anumula KR. 2006. Advances in fluorescence derivatization method for high-performance liquid chromatographic analysis of glycoprotein carbohydrates. Anal Biochem. 350:1-23).Ko te N-Acetylglucosamine (GlcNAc) me te N-acetyllactosamine i whakamahia hei kaiwhiwhi me te uridine diphosphate (UDP) -galactose me te cytidine monophosphate (CMP) -N-acetylneuraminic acid (NANA) hei kaituku mo GalT-1 me ST-6, ia.I tapaina nga hua enzymatic ki te waahi me te AA, ka wehea mai i nga taputapu i runga i te tiwae TSKgel Amide 80 ma te whakamahi i nga tikanga-waahanga noa.I whakatauhia nga waeine enzyme mai i nga waahi teitei ma te whakatairite ki nga paerewa kua whakaemihia Gal-β1-4GlcNAc me NANA-α2-6 Gal-β1-4GlcNAc.Ko te raina (te wa me te kukū o te enzyme), te tika (intra-me te interassay) me te tukurua mo nga whakamatautau i whakapumautia.I kitea he pai nga whakamatautau ki te aro turuki i nga mahi o te whaariki i te wa e wehe ana me te purenga.He tino tairongo nga whakamatautau, he rite, he pai ake ranei i nga inenga huka iraruke tuku iho.Ka taea hoki te whakamahi i te whakatakotoranga whakamatautau mo te ine i te mahi o etahi atu whakawhitinga, mena kei roto i nga kaiwhakaae warowairo he mutunga whakaheke mo te tapanga.I whakawhanakehia he whakamatautau mo te hunga whakaae glycoprotein ma te whakamahi i te IgG.I hangaia he tikanga whakamohiotanga HPLC poto mo te wehenga o nga glycans IgG (bintennary G0, G1, G2, mono- me te disialylated), i tere te whakatau i nga mahi GalT-1 me ST-6.I tua atu, me whai hua tenei tikanga tohu mo te aro turuki i nga huringa o nga IgG glycans i nga waahi haumanu.
