4. Nyamuneka kora reaction ukurikije ibihe bikurikira:
(1) Niba Primer Primer ikoreshwa, reaction igomba gukorwa kuri 25 ℃ kuri 10mins, hanyuma kuri 50 ℃ kuri 30 ~ 60mins;
(2) Niba hakoreshejwe Oligo dT cyangwa primers yihariye, reaction igomba gukorwa kuri 50 ℃ kuri 30 ~ 60mins.
5.Shyushya kuri 95 ℃ kuri 5mins kugirango udakora Neoscript Reverse Transcriptase no guhagarika reaction.
6.Ibicuruzwa byandukuwe birashobora gukoreshwa muburyo bwa PCR hamwe na fluorescence igereranya PCR reaction, cyangwa ikabikwa kuri -20 ℃ igihe kirekire.
