Gel electrophoresis waxaa lagu qaban karaa mid toosan ama toosan. Jeerayaasha horizontal waxay caadi ahaan ka kooban yihiin matrix agarose ah. Cabbirrada daloolada ee jel-yadani waxay ku xiran yihiin xoojinta qaybaha kiimikada: daloolada agarose gel (100 ilaa 500 nm dhexroor) way ka weyn yihiin oo ka yar yihiin labbiska marka la barbardhigo gelpores acrylamide (10 ilaa 200 nm dhexroor). Marka la barbardhigo, DNA iyo RNA molecules way ka weyn yihiin xargaha toosan ee borotiinka, kuwaas oo inta badan la diido ka hor, ama inta lagu jiro habkan, taas oo ka dhigaysa inay si sahlan u falanqeeyaan. Sidaa darteed, DNA-da iyo molecules RNA waxay inta badan ku shaqeeyaan gels agarose (horizontally) .Nidaamkayaga DYCP-31DN waa nidaamka electrophoresis siman. Qalabkan jel-ka-soo-baxa ee la qaabeeyey wuxuu samayn karaa 4 cabbir oo kala duwan oo jeel ah iyadoo la raacayo saxaarad jel oo kala duwan.
