| Adhbhar: | Tha 4- hydroxyethyl piperazine ethyl sulfonic acid na bufair bith-eòlasach; Ath-bhualadh sgaradh agus mion-sgrùdadh bufair co-phàirtean RNA, bufair, bufair hybridization ro-làimh; Air a chleachdadh airson comharrachadh RNA agus T4RNA ligase 3'- terminal; Air a chleachdadh ann an uidheamachd sgrùdaidh bith-cheimiceach, pasgan às-tharraing DNA / RNA agus innealan sgrùdaidh PCR. Gu gnìomh ceallan gun dìon. Is e seòrsa de bhufair ian haidridean a th’ ann, is urrainn dha smachd a chumail air farsaingeachd luach pH an seasmhach airson ùine mhòr. Cleachd an dùmhlachd mu dheireadh de chlaonadh 10-50 airson L, dh’ fhaodadh meadhan cultar coitcheann anns a bheil comas buffering 20 LHEPES claonadh a choileanadh. |
