What percentage gel should be used if you want to separate DNA fragments that are 25,000 bp , 21,000 bp, 10,000 bp and 6,000 bp?

Best ResponseYou've already chosen the best response.2If we don't have this factor it can be hard to know becuase the driving force of the molecule or DNA is given by: \[f=6 \pi \eta r\] Here f is the driving force, η is the viscosity of the medium and r is the radius of a sphere.

Best ResponseYou've already chosen the best response.2But if using a agarose gel I would say about 0,5 % agarose, that should cover 1k to 30k.

Best ResponseYou've already chosen the best response.2Well this is college bio, so I wonder if you don't have any tables to look in, I only found it, becuase I had a old table from a prof of mine. The eqautions however is stright on ;)

Best ResponseYou've already chosen the best response.0you perform a restiction digest that should yield 1400 bp, 1080 bp, and 400 bp fragments. You check the restiction digest by running it on a gel that is 1.5 %, the correct percentage. but you're in a rush and only partially run the gel you also forget to load the marker

Best ResponseYou've already chosen the best response.0when you stain the gel you only see three bands in the lane you loaded. The second band from the well is more intense than thr others and looks like a doublet. which 2 fragements make up the double? why? what could you do to further separate the fragemnts to verify this?

Best ResponseYou've already chosen the best response.0oh, okay thank you though! how about this one > if you want to run gel electrophoresis at 100 v for two hours instead of one (which is how long it should take) what should you do?

Best ResponseYou've already chosen the best response.2Hmmm an increase in running time will allow the bands to separate even more... wich you ofcuase need to take into account if you make a aproximation. Beside from that, I most again say I'm not sure.

Best ResponseYou've already chosen the best response.2Might also need to adjust some equations if you have some formular that have bps as a function of length of bands travel.

Best ResponseYou've already chosen the best response.0i was thinking that you could rin it at half the voltage (50 v)

Best ResponseYou've already chosen the best response.2Oh, then i misunderstod well depends if voltage and time is porportional ;)
