Uluhlu lufakiwe

Emva kokuba ikholamu iplagwe, isivuno se-RNA sincitshisiwe okanye akunakwenzeka ukuhlambulula i-RNA, kwaye ubunzima obufunyenweyo be-RNA buphantsi.

Uhlalutyo lwesizathu esiqhelekileyo:

1. Uqhawulo lwesampulu alucokisekanga.

Ukuqhekeka kwesampuli akubangeli ngokupheleleyo i-DNA-CLEANING COLUMN ukuba ivalwe, ngelixa ichaphazela isivuno se-RNA kunye nomgangatho.Sincoma umsebenzi wokusila ngokukhawuleza kwi-nitrogen engamanzi eyaneleyo xa uqhekeza iisampuli, Zama ukutyumza udonga lweseli yesampuli, inwebu yeseli kunye nezinye iithishu.Kwiisampuli zezityalo ze-polyol polysaccharides, sincoma ukuba usebenzise i-Plant Total RNA IOLATION KIT PLUS.

2. Xa ufunxa isampulu eyohluliweyo ye-supernatant nge-DNA-Cleaning Column, i-cell fragmented precipitate enokwenzeka inokuphefumlelwa.

Iintlenga eziqhekekileyo zeseli ezithathiweyo ziya kubangela iKholamu ye-RNA KUPHELA eya kuvalelwa xa kusenziwa umsebenzi we-adsorption we-RNA (bona inyathelo lesi-6).Siyakucebisa ngononophelo xa ufunxa le supernatant ukunqanda ubugoxo beeseli ukuba bufunxe.

3. Isixa sokuqala sesampulu sininzi kakhulu.

Ukusetyenziswa kwesampulu ngokugqithisileyo kuya kubangela ukuqhekeka kwesampulu engaphelelanga okanye i-cell lysis engaphelelanga yi-Buffer PSL1, okukhokelela ekuvalelekeni kwekholamu yokucoca ngexesha lokuhlanjululwa.I-Plant Total RNA Isolation Kit Isampuli nganye yokusebenza ecocekileyo yi-50 mg.Kwiisampulu zezityalo ze-polysaccharides ze-polyol, sincoma ukuba uzame i-Plant Total RNA IOLATION KIT PLUS.

4. Ubushushu be-centrifuge buphantsi kakhulu.

Yonke i-RNA yodwa kunye nenkqubo yokucoca iqhutyelwa kwindawo yokushisa (20-25°C), ngaphandle kokuba isampulu ithishu yaphulwe yinitrogen engamanzi.Ubushushu bezinye iicentrifuge zecryogenic bungaphantsi kwama-20.℃, enokubangela ukuvaleka kweKholamu yokucoca i-DNA kunye/okanye i-RNA-Only Column.Ukuba oku kwenzeka, setha ubushushu be-centrifuge ukuya kuma-20-25℃, kwayeqinisekisa ukuba umxube we-lysis kunye/okanye i-ethanol-eyongeziweyo ye-supernatant yayifudunyezwe ibe ngama-37°C.

Akukho RNA ekhutshiweyo okanye isivuno se-RNA siphantsi

Ngokuqhelekileyo kukho izinto ezininzi ezichaphazela ukusebenza kakuhle kokubuyisela, njenge: umxholo we-RNA yesampuli, indlela yokusebenza, umthamo we-lution, njl.

Uhlalutyo lwezizathu eziqhelekileyo zingezantsi:

I-1.I-ice bath okanye ukushisa okuphantsi (4 ° C) i-centrifugation yenziwa ngexesha lokusebenza.

Icebiso: Isebenza kwiqondo lobushushu begumbi (15-25°C) kuyo yonke inkqubo, musa ukwenza i-ice bath kunye ne-centrifugation yobushushu obuphantsi.

I-2.I-RNA iye yachithwa ngenxa yokugcinwa okungafanelekanga kwesampuli okanye ukugcinwa kwexesha elide lesampuli.

Isindululo: Iisampulu ezisandula ukuqokelelwa kufuneka zikhe zikhenkcezwe ngokukhawuleza kwinitrogen engamanzi, emva koko zigcinwe ku -80°C ixesha elide, zithintele ukuphinda kukhenkceze kunye nokunyibilika kweisampulu;okanye ngokukhawuleza ucwilise iisampuli kwi-RNA stabilizer RNAlater isisombululo (iisampulu zezilwanyana).

I-3.Ukwahlulwa kwesampulu enganelanga kunye ne-lysis kukhokelela ekuvinjweni kwekholamu yokucoca.

Isiphakamiso: Xa ugaya i-tissue, nceda uqinisekise ukuba i-tissue iphantsi ngokwaneleyo, kwaye ngokukhawuleza uyidlulisele kwi-Buffer ye-PSL1 elungiselelwe ngaphambili (qinisekisa ukuba umlinganiselo ochanekileyo we-β-ME wongezwe, jonga inyathelo 1 lenkqubo).

4.I-eluent yongezwa ngokungalunganga.

Ingcebiso: Qinisekisa ukuba i-ddH2O ye-RNase-Free ithontsizelwe embindini we-membrane yekholamu yokucoca.

5.Umthamo ochanekileyo we-ethanol epheleleyo ayizange yongezwe kwi-Buffer PSL2 okanye i-Buffer PRW2.

Ingcebiso: Nceda ulandele imiyalelo, yongeza umthamo ochanekileyo we-ethanol epheleleyo kwi-Buffer PSL2 kunye ne-Buffer PRW2 kwaye udibanise kakuhle phambi kokuba ikhithi isetyenziswe.

6.Ubungakanani besampulu yethishu ayifanelekanga.

Ingcebiso: Sebenzisa i-50 mg yethishu nge-500 μl ye-Buffer PSL1.Ukusebenzisa izicubu ezininzi kakhulu kuya kunciphisa inani le-RNA ekhutshiweyo kwaye ukucoceka kwe-RNA okubangelwayo kuya kuncitshiswa.Sincoma kakhulu ukuba idosi yesampulu yokuqala ayifanele idlule i-50 mg ngomsebenzi wokutsalwa kwe-RNA.

7.Ivolume ye-elution engafanelekanga okanye i-elution engaphelelanga.

Isiphakamiso: Umthamo ocacileyo wekholamu yokucoca ngu-50-200 μl;ukuba i-elution effect ayinelisi, kuyacetyiswa ukuba kwandiswe ixesha kwiqondo lobushushu legumbi emva kokongeza i-ddH2O ye-RNase-Free preheated, efana ne-5-10min.

I-8.Ikholamu yokucoca inentsalela ye-ethanol emva kokuhlamba nge-BufferPRW2.

Isiphakamiso: Ukuba ityhubhu engenanto i-centrifuged ye-1 min kwaye kusekho i-ethanol eseleyo emva kokuhlamba kwi-Buffer PRW2, unokwandisa ixesha le-tube engenanto ye-centrifugation ukuya kwi-2 min, okanye ubeke ikholamu yokucoca kwindawo yokushisa ye-5 min ukususa ngokupheleleyo i-ethanol eseleyo.

9.Ikhithi isetyenziswe ngokungachanekanga.

Isiphakamiso: Kwiisampuli zezityalo ze-polyphenolic polysaccharides, ukusebenzisa iikiti eziqhelekileyo ezifana ne-Plant Total RNA Isolation Kit ayinakukwazi ukufumana iisampulu ezifanelekileyo ze-RNA.Sincoma ukuba usebenzise iPlant Total RNA IsolationKit Plus, eyilelwe ngokukodwa iisampuli zezityalo ze-polyphenolic polysaccharide.Ikhithi ephuhliswe ngokukodwa ukukhupha i-RNA kwi-polyphenol kunye neesampuli zezityalo ze-polysaccharide.

Ixabiso le-OD260/OD280 liphantsi

I-RNA elution ene-ddH2O kwaye isetyenziselwa ukufundwa kwe-spectrophotometer iphumela kumaxabiso aphantsi e-OD260/OD280.Sincoma ukusebenzisa i-10 mM Tris-HCl, i-pH 7.5 (kunokuba i-RNase-Free ddH2O yokukhupha i-RNA) ukufumana amaxabiso achanekileyo e-OD260/OD280, bona “i-RNA Concentration and Purification Assays” kwiphepha le-19.

I-RNA ehlanjululweyo ithotywa

Umgangatho we-RNA ecocekileyo inxulumene nezinto ezifana nokugcinwa kwesampulu, ukungcoliseka kwe-RNase, kunye nokukhwabanisa.

Uhlalutyo lwezizathu eziqhelekileyo:

I-1.Iisampulu ze-tissue azizange zigcinwe ngexesha emva kokuqokelela.

Isincomo: Ukuba iisampulu zezicubu azisetyenziswanga ngexesha emva kokuqokelela, nceda uzigcine kwi-nitrogen engamanzi kwiqondo lokushisa eliphantsi ngokukhawuleza okanye uzidlulisele kwi--80 ° C yokugcina ixesha elide emva kokuqhwala ngokukhawuleza kwi-nitrogen engamanzi, okanye ngokukhawuleza ucwilise iisampuli kwi-RNA stabilizer RNAlater isisombululo (iisampulu zezilwanyana).Ukukhutshwa kwe-RNA, zama ukusebenzisa iisampulu zeethishu ezisanda kuqokelelwa.

2.Ukukhenkceza okuphindaphindiweyo kunye nokunyibilika kweesampuli zethishu.

Icebiso: Xa ugcina iisampulu zethishu, kungcono ukuzisika zibe ziingceba ezincinci ukuze zigcinwe, kwaye ukhuphe inxalenye yazo xa uzisebenzisa ukuthintela ukonakaliswa kweRNA okubangelwa kukukhenkcezwa okuphindaphindiweyo nokunyibilika kweisampulu.

3.I-RNase yaziswa kwigumbi lokusebenza okanye inganxitywanga iiglavu ezilahlwayo, iimaski, njl.

Ingcebiso: Imifuniselo yokutsalwa kwe-RNA yenziwa ngcono kwimisebenzi eyahlukeneyo ye-RNA, kwaye itafile yelabhoratri kufuneka icocwe phambi kovavanyo, kwaye iiglavu ezilahlwayo kunye nemaski kufuneka zinxitywe ngexesha lovavanyo ukunqanda ukuthotywa kwe-RNA okubangelwa kukwaziswa kwe-RNase ngowona mgangatho mkhulu.

I-4.I-reagent ingcolisekile yi-RNase ngexesha lokusetyenziswa.

Ingcebiso: Faka endaweni yoluhlu olutsha lwezixhobo ze-RNA zokutsalwa kwezityalo zizonke zemifuniselo enxulumeneyo.

I-5.Iibhubhu ze-centrifuge kunye neengcebiso ze-pipette ezisetyenziselwa ukuguqulwa kwe-RNA zingcolile nge-RNase.

Ingcebiso: Qinisekisa ukuba iityhubhu ze-centrifuge, iingcebiso ze-pipette, ii-pipettes, njl njl. ezisetyenziswa kwi-RNA extraction zonke zi-RNase-Free.
