I-Gel electrophoresis yenye yeendlela eziphambili ezisetyenziswa kwibhayoloji ye-molekyuli yohlalutyo lwe-DNA. Le ndlela ibandakanya ukufuduka kwamaqhekeza e-DNA ngokusebenzisa ijeli, apho yahlulwe ngokusekelwe kubukhulu okanye imilo. Nangona kunjalo, ngaba ukhe wadibana naziphi na iimpazamo ngexesha lovavanyo lwakho lwe-electrophoresis, njengeebhendi eziqatyiweyo kwijeli ye-agarose, okanye akukho bands kwijeli? Yintoni enokuba ngunobangela wezi mpazamo?
Iingcali zethu ziye zashwankathela izibini zokusombulula ingxaki apha kwireferensi yakho.
1. Iibhanti eziqatyiweyo kwijeli yeagarose
●I-DNA yathotywa. Kulumkele ukungcoliseka kwe-nuclease.
● Isithinteli se-electrophoresis asikho ntsha. Emva kokusetyenziswa ngokuphindaphindiweyo kwe-electrophoresis buffer, amandla e-ionic ayancipha, kwaye ixabiso layo le-pH liyenyuka, ngoko umthamo we-buffer uyancipha, ochaphazela umphumo we-electrophoresis. Kucetyiswa ukuba utshintshe isithinteli se-electrophoresis rhoqo.
● Iimeko ezingafanelekanga ze-electrophoresis zasetyenziswa. Ungavumeli i-voltage ukuba idlule i-20 V / cm, kwaye ugcine izinga lokushisa <30 ° C ngexesha le-electrophoresis. Kwi-DNA strand electrophoresis enkulu, iqondo lobushushu kufuneka libe ngu-<15° C. Jonga i-electrophoresis buffer inomthamo owaneleyo we-buffer.
● I-DNA eninzi kakhulu yafakwa kwijeli. Nciphisa inani le-DNA.
● Ityuwa eninzi kwiDNA. Sebenzisa i-ethanol precipitation ukususa iityuwa ezingaphezulu.
● I-DNA yayineprotini. Sebenzisa i-phenol extractions ukususa iiprotheyini eziphambili.
● I-DNA yatshintshwa. Musa ukufudumala phambi kwe-electrophoresis. Nciphisa i-DNA kwi-buffer nge-20 mM NaCl.
2. I-Anomalies DNA band migration
● Ukuhlaziywa kwendawo ye-COS yeqhekeza le-λHind III. Fudumeza i-DNA imizuzu emi-5 ngaphantsi kwe-65° C phambi kwe-electrophoresis, uze uyipholise kwiyunithi yomkhenkce imizuzu emi-5.
● Iimeko ezingafanelekanga ze-electrophoresis zasetyenziswa. Ungavumeli i-voltage ukuba idlule i-20 V / cm, kwaye ugcine izinga lokushisa <30 ° C ngexesha le-electrophoresis. Jonga i-electrophoresis buffer inomthamo owaneleyo we-buffer.
● I-DNA yatshintshwa. Musa ukufudumala phambi kwe-electrophoresis. Nciphisa i-DNA kwi-buffer nge-20 mM NaCl.
3. Ukufa isiqaqa okanye akukho bhanti zeDNA kwijeli yeagarose
● Bekukho umyinge onganelanga okanye ukugxilwa kwe-DNA efakwe kwijeli. Yandisa inani le-DNA. I-Polyacrylamide gel electrophoresis inovakalelo kancinci kune-agarose electrophoresis, kwaye ukulayishwa kwesampulu kunokwehliswa ngokufanelekileyo.
● IDNA yonakala. Kulumkele ukungcoliseka kwe-nuclease.
● I-DNA yafakwa kwijeli ye-electrophore. I-Electrophorese i-gel ixesha elincinci, sebenzisa i-voltage ephantsi, okanye usebenzise i-gel ephezulu yeepesenti.
● Umthombo wokukhanya we-W ongafanelekanga wasetyenziselwa ukubonwa kwe-ethidium bromide-stained DNA. Sebenzisa ubude obufutshane (254 nm) W ukukhanya ngovakalelo olukhulu.
4. Iibhanti zeDNA azikho
●Ubungakanani obuncinci be-DNA benziwe nge-electrophoresed ngaphandle kwejeli. I-Electrophorese i-gel ixesha elincinci, sebenzisa i-voltage ephantsi, okanye usebenzise i-gel ephezulu yeepesenti.
● Kunzima ukwahlula amaqela e-DNA eemolekyuli ezifanayo. Yandisa ixesha le-electrophoresis, kwaye ujonge ukugxilayejeli ukuqinisekisa ukuba ijeli echanekileyo ngokwepesenti ekufuneka isetyenziswe.
● I-DNA yatshintshwa. Musa ukufudumala phambi kwe-electrophoresis. Nciphisa i-DNA kwi-buffer nge-20 mM NaCl.
● Imisonto ye-DNA mikhulu, kwaye ijeli ye-electrophoresis eqhelekileyo ayifanelekanga. Hlalutya kwi-pulse gel electrophoresis.Yeyiphi eminye imiba okhe waba nayo nge-agarose gel electrophoresis? Siza kuphanda ngakumbi kwizikhokelo kwixesha elizayo.
