Could someone please explain to me what both these are for ? I've tried searching the internet and i honestly cannot find something which explains the difference between the? Pleasee, even a link explaining them both in detail would do.

I don't understand what is the point of them both? are these used together?

A Southern blot is a method routinely used in molecular biology for detection of a specific DNA sequence in DNA samples. Southern blotting combines transfer of electrophoresis-separated DNA fragments to a filter membrane and subsequent fragment detection by probe hybridization. The method is named after its inventor, the British biologist Edwin Southern.[1] [derived from Wikipedia]

But, gel electrophoresis is a part (usually the primary step) of many techniques; such as northern, southern & western blots ....etc.

Hope that helps

Just a minor pedantic point, but you should always write Southern blotting with a capital S because it's named after the guy who invented it - Edwin Southern.

Then some joker scientists named their techniques northern blot, eastern blot and western blot as a piss-take.

That might make more sense as to why they called a DNA technique after a compass direction (ie. it's not).

Just a small point, but it's not all forensic science stuff. I use agarose gel electrophoresis for DNA analysis pretty much every day, and I'm yet to solve a crime :p:
