WebNow let's talk about the two kinds of gels that are most commonly used. The first is agarose, and the second is SDS-PAGE. So agarose is a gel that's usually used for separating big pieces of DNA. So if you think about the pore size in the agarose, it has pretty big pores, so imagine it looking kind of like this. WebPCR products are most commonly analyzed by agarose gel electrophoresis. The results can be visualized by ethidium bromide or non-toxic dyes such as SYBR ® green.
