Isihluthulelo sempumelelo yethu "Ikhwalithi Yomkhiqizo Enhle, Inani Elizwakalayo kanye Nesevisi Ephumelelayo" yeI-China Nucleic Acid Extraction, Ikhithi yokukhipha i-Rna, Impahla eyinhloko yenkampani yethu isetshenziswa kabanzi emhlabeni wonke;U-80% wemikhiqizo yethu ithunyelwa e-United States, Japan, Europe nakwezinye izimakethe.Zonke izinto ezamukeleke ngobuqotho izivakashi zizovakashela imboni yethu.

Incazelo

Le khithi isebenzisa ikholomu yokuphotha kanye nefomula eyakhiwe yi-Foregene, engakhipha ngempumelelo i-RNA ephezulu nekhwalithi ephezulu kumaseli akhuliswe ngamapuleti emithombo engu-96, 24, 12, kanye ne-6.

Ikhithi inikeza Ikholomu Yokuhlanza I-DNA esebenza kahle, engahlukanisa kalula i-supernatant ne-cell lysate, ibophe futhi isuse i-genomic DNA.Ukusebenza kulula futhi konga isikhathi.

Ikholomu ye-RNA kuphela ingahlanganisa ngempumelelo i-RNA ngefomula ehlukile.Inani elikhulu lamasampula lingacutshungulwa kanyekanye.

Izingxenye zekhithi

*Sicela ugqoke amagilavu ​​futhi uthathe izinyathelo zokuvikela ngesikhathi sokusebenza njengoba i-Buffer cRL1 ne-Buffer RW1 iqukethe usawoti we-chaotropic ocasulayo.

Izici&izinzuzo

■ Yonke inqubo iqhutshwa ekamelweni lokushisa (15-25 ℃), ngaphandle kokugeza kweqhwa kanye nokushisa okuphansi kwe-centrifugation.

Isikhathi Esifushane Sokuhola seI-China Nucleic Acid Extraction, Ikhithi yokukhipha i-Rna, Impahla eyinhloko yenkampani yethu isetshenziswa kabanzi emhlabeni wonke;U-80% wemikhiqizo yethu ithunyelwa e-United States, Japan, Europe nakwezinye izimakethe.Zonke izinto ezamukeleke ngobuqotho izivakashi zizovakashela imboni yethu.

I-RNA ayikhishiwe noma isivuno se-RNA siphansi

Kuvame ukuba nezinto ezihlukahlukene ezithinta ukusebenza kahle kokululama, njengalezi: okuqukethwe kwesampula yezicubu ze-RNA, indlela yokusebenza, ivolumu ye-elution, njll.

1. Ukugeza kweqhwa noma i-cryogenic (4 °C) i-centrifugation yenziwa ngesikhathi sokusebenza.

Okutuswayo: Sebenzisa ekamelweni lokushisa (15-25 ° C) kuyo yonke inqubo, ungabhavi eqhweni kanye ne-centrifuge emazingeni okushisa aphansi.

2. Ukulondolozwa kwesampula okungalungile noma isikhathi sokugcina isampula eseqile.

Okutuswayo: Gcina amasampula ku--80 °C noma ufrize ku-nitrogen ewuketshezi futhi ugweme ukusetshenziswa okuphindaphindiwe kokuqhwaza;zama ukusebenzisa izicubu ezintsha noma amaseli akhulisiwe ukuze kukhishwe i-RNA.

3. Isampula yesampula enganele.

Okutuswayo: Uma wenza izicubu zibe homogenizing, qinisekisa ukuthi izicubu zihlanganiswe ngendlela eyanele nokuthi amaseli ezicubu ahlukaniswe ngokwanele ukuchaza ukukhululwa kwe-RNA.

4. I-eluent ayengezwanga ngendlela efanele.

Okunconyiwe: Qinisekisa ukuthi i-RNase-Free ddH₂U-O wengezwa ngokudonsela phansi maphakathi nolwelwesi lwekholomu yokuhlanza.

5. Ivolumu elungile ye-ethanol ephelele ayizange yengezwe ku-Buffer RL2 noma ku-Buffer RW2.

Isincomo: Landela imiyalelo, engeza ivolumu efanele ye-ethanol ephelele ku-Buffer RL2 kanye ne-Buffer RW2 bese uxuba kahle ngaphambi kokusebenzisa ikhithi.

6. Umthamo wesampula wezicubu awufanelekile.

Isincomo: Sebenzisa i-10-20 mg yezicubu noma (1-5) × 10⁶amaseli nge-500 μl buffer RL1, njengoba ukusetshenziswa kwezicubu ngokweqile kungaholela ekukhishweni kwe-RNA okuncishisiwe.

7. Ivolumu ye-elution engafanele noma ukukhishwa okungaphelele.

Okutuswayo: Ivolumu ye-elution yekholomu yokuhlanza ingu-50-200 μl;uma umphumela we-elution ungagculisi, kuyanconywa ukuthi kunwetshwe isikhathi sokubeka izinga lokushisa legumbi ngemva kokwengeza i-ddH eshisiwe ye-RNase-Free₂O, isb imizuzu emi-5-10.

8.Ikholomu yokuhlanza inensalela ye-ethanol ngemva kokugeza kwe-Buffer RW2.

Okutuswayo: Uma kunensalela ye-ethanol ngemva kokugeza kwe-Buffer RW2, i-tube centrifugation engenalutho ye-1min, isikhathi sokusebenza kwe-tube centrifugation esingenalutho singanyuswa sibe yi-2min, noma ikholomu yokuhlanza ingabekwa ekamelweni lokushisa imizuzu emi-5 ukuze kukhishwe ngokwanele i-ethanol esele.

I-RNA ehlanziwe yehlisiwe

Ikhwalithi ye-RNA ehlanzekile ihlobene nezici ezifana nokulondolozwa kwesampula, ukungcoliswa kwe-RNase, nokukhohlisa, njll.

1. Amasampula ezicubu awagcinwa ngesikhathi.

Okutuswayo: Uma amasampula ezicubu noma amaseli engasetshenziswa ngesikhathi esifanele ngemva kokuqoqwa, londoloza ngokushesha i-cryopreserve ku- -80 °C noma i-nitrogen ewuketshezi.Ukuze ukhiphe i-RNA, sebenzisa ithishu esanda kuthathwa noma isampula yeseli noma nini lapho kunokwenzeka.

2. Ukuqhwaza okuphindaphindiwe kwamasampula ezicubu.

Okutuswayo: Uma ugcina amasampula ezicubu, kuhle kakhulu ukuwasika abe izingcezu ezincane ukuze alondolozwe, bese ususa ingxenye eyodwa yezingcezu lapho uzisebenzisa ukugwema ukuncibilika okubandayo kwesampula kanye nokonakala kwe-RNA.

3. I-RNase yethulwa noma ingagqoki amagilavu ​​alahlwayo, imaski, njll. phakathi nokuhlinzwa.

Okunconyiwe: Ukuhlolwa kokukhipha i-RNA kwenziwa kangcono kakhulu emagumbini okukhohlisa e-RNA ahlukene futhi ithebula liyasulwa ngaphambi kokuhlolwa.

Gqoka amagilavu ​​alahlwayo kanye nemaski ngesikhathi sokuhlolwa ukuze unciphise ukucekelwa phansi kwe-RNA okubangelwa ukwethulwa kwe-RNase.

4. Ama-reagents angcoliswe yi-RNase ngesikhathi sokusetshenziswa.

Okunconyiwe: Faka esikhundleni Ikhithi Yokuhlukanisa Yezilwane Ephelele Yenani Le-RNA ukuze uthole ukuhlolwa okuhlobene.

5. Amashubhu e-centrifuge, amathiphu, njll. asetshenziswa ekukhohlisweni kwe-RNA angcoliswe yi-RNase.

Okutuswayo: Qinisekisa ukuthi amashubhu e-centrifuge, amathiphu, amapayipi, njll. asetshenziswa ekukhishweni kwe-RNA konke Akuna-RNAse.

I-RNA etholiwe ehlanziwe ithinta ukuhlola okwehla nomfula

I-RNA ehlanjululwe ngekholomu yokuhlanza, uma ama-ion kasawoti, okuqukethwe kwamaprotheni kukukhulu kakhulu kuzothinta isilingo esisezansi nomfula, njengokuthi: ukuloba okuhlanekezelwe,Northern Blot et al.

1. I-RNA ekhishiwe inezinsalela ze-ion kasawoti.

Okunconyiwe: Qinisekisa ukuthi ivolumu elungile ye-ethanol yengezwe ku-Buffer RW2 futhi wenze amakholomu okuhlanza ama-2 ageza ngesivinini esimaphakathi esikhonjiswe ukusebenza;uma kukhona noma iyiphi insalela ye-ion kasawoti, shiya ikholomu yokuhlanza ku-Buffer RW2 imizuzu engu-5 ekamelweni lokushisa futhi wenze i-centrifugation ukwandisa ukukhishwa kokungcoliswa kukasawoti.

2. Izinsalela ze-Ethanol ku-RNA elutioned.

Okutuswayo: Qinisekisa ukuthi ngemva kokugeza i-buffer RW2, yenza umsebenzi ongenalutho we-tube centrifugation ngesivinini se-centrifugation esikhonjiswe ukusebenza, wandise isikhathi sokusebenza kwe-tube centrifugation esingenalutho sibe yimizuzu emi-2 uma kusekhona insalela ye-ethanol, noma uyishiye ekamelweni lokushisa amamitha angu-5.
