Porogaramu
1. Ibikoresho byo gusuzuma
2. Ibikoresho byo gukuramo RNA na ADN
3. Gukuramo ibice bitari poroteyine biva mu ngingo, kwangirika kwa poroteyine, nkinkingo za ADN no gutegura heparin
4. Gutegura ADN ya chromosome na pulsed electrophorei
5. Iburengerazuba
6. Enzymatique glycosylated albumin reagents mugupima vitro
Kwirinda
Wambare uturindantoki two kurinda hamwe na gogles mugihe ukoresha cyangwa upima, kandi ukomeze guhumeka neza nyuma yo kubikoresha.Iki gicuruzwa gishobora gutera uruhu rwa allergique no kurwara amaso.Niba ihumeka, irashobora gutera allergie cyangwa ibimenyetso bya asima cyangwa dyspnea.Birashobora gutera uburakari.
Suzuma
Igisobanuro cyibice
Igice kimwe (U) gisobanurwa nkubunini bwa enzyme isabwa kuri hydrolyze casein kugirango itange 1 μ mol tyrosine kumunota mubihe bikurikira.
Reagents kwitegura
Reagent I: 1g amata yamata yashonga muri 50ml yumuti wa 0.1M sodium fosifate (pH 8.0), yashizwemo mumazi 65-70 ℃ mumazi 15mins, akayungurura akayashonga, akonjeshwa namazi, agahindurwa na hydroxide ya sodium kuri pH 8.0, nubunini bugenwe. 100ml.
Reagent II: 0.1M acide trichloroacetic, 0.2M sodium acetate, 0.3M acide acetike.
Reagent III: 0.4M Na2CO3igisubizo.
Reagent IV: Forint reagent ivanze namazi meza inshuro 5.
Reagent V: enzyme diluent: 0.1M sodium fosifate yumuti (pH 8.0).
Reagent VI: igisubizo cya tirozine: 0, 0.005, 0.025, 0.05, 0.075, 0.1, 0,25 umol / ml tirozine yashonga hamwe na 0.2M HCL.
Inzira
1. 0.5ml ya reagent Nashyutswe mbere kuri 37 ℃, ongeramo 0.5ml yumuti wa enzyme, vanga neza, kandi ube kuri 37 ℃ kuri 10mins.
2. Ongeramo ml 1 ya reagent II kugirango uhagarike reaction, vanga neza, kandi ukomeze incubation kuri 30mins.
3. Centrifugate igisubizo cyibisubizo.
4. Fata 0.5ml ndengakamere, ongeramo 2.5ml reagent III, 0.5ml reagent IV, vanga neza hanyuma ushire kuri 37 ℃ kuri 30mins.
5. OD660yagenwe nka OD1;itsinda rishinzwe kugenzura ubusa: 0.5ml reagent V ikoreshwa mugusimbuza enzyme igisubizo kugirango umenye OD660nka OD2, ΔOD = OD1-OD2.
6660kubintu bitandukanye bya L-tyrosine, hanyuma ibona umurongo usanzwe Y = kX + b, aho Y ni L- tyrosine, X ni OD600.
