Electrophoresis relies on a basic process — particles moving in an electric field. Known for more than 200 years, this phenomenon still drives fundamental techniques in many labs and its long history plays a role in the widespread use of the technology. Current interest lies in making the technology, faster, more accurate and more sensitive.
9 Questions You Should Ask When Buying Electrophoresis Equipment and Gels
- How many gels per experiment can you run at once in a single electrophoresis cell?
- Can you run hand cast and precast gels with the same electrophoresis equipment?
- Can you blot in the same tank as you run the gels?
- How fast can you run a set of gels with optimal performance?
- How fast can you visualize your proteins in the gel?
- Do you need any special buffers or sample buffer to run your gel?
- Does a precast gel give you the same separation as a hand cast gel?
- How fast can you transfer proteins from your gel to a membrane?
- How efficiently can you transfer your high MW proteins from your gel to a membrane?
