Calaamadaha DNA-da ee ay soo saarto shirkadeena waxaa dhamaantood lagu helaa dheefshiidka enzyme ee plasmids.Calaamadeeyayaasha uu soo saaray habkani waxay leeyihiin asal nadiif ah, xargo cad, tayo xasiloon waxayna gaari karaan qiyaas sax ah oo calaamadeyaal ah.Badeecadu waxay ka kooban tahay laba midab (dheeg cyan iyo jaalle ah), iyo heerka socdaalka ee electrophoresis waxaa lagu xukumi karaa isbeddelka midabka inta lagu jiro electrophoresis.Heerka socdaalka ee dheeha cyan waxay la mid tahay kan 3-5kb ee 1% agarose jel, heerka socdaalka dheeha jaalaha ah wuxuu ku saabsan yahay Heerka guuritaanka wuxuu la mid yahay kan 50bp band, iyo horumarka electrophoresis si toos ah ayaa loo arki karaa iyada oo isha qaawan.Way fududahay in la isticmaalo oo sawirka electrophoresis waa cad yahay.

Alaabtani waa badeeco diyaar u ah in la isticmaalo oo waxay ka kooban tahay 1x Loading Buffer.Waxaad si toos ah u qaadan kartaa qaddar ku habboon calaamadeeyaha electrophoresis iyadoo loo eegayo baahida tijaabada ah.BM5000 DNA Marker wuxuu ka kooban yahay 8 xabo oo DNA ah, xargaha DNA-du waa: 100bp(50ng/5μl), 250bp(50ng/5μl), 500bp(50ng/5μl), 750bp(75ng/5μl), 1000bp(50ng/5μl), 3μl(50ng/5μl), 0bp(30ng/5μl), 5000bp(50ng/5μl).
