OwlElectrophoresisSystem
Buffer and gel volumes for various Owl-brand horizontal gel electrophoresis systems. Make up the amount of AgaroseGelBuffer listed under "total buffer volume" and then take from that the amount listed as "gel volume" to make the gel. Add EthidiumBromide (0.5 μg/ml of gel) to the melted gel before pouring.

Note: running the gel at the optimal voltages listed (5 V per cm distance between electrodes) will result in the best resolution of bands. Gels can be run at higher voltages, but may suffer temperature and/or pH effects. At lower voltages gels take longer to run which may result in increased diffusion of bands. Practically, there is a considerable range of voltages that will give an acceptable result and, within reason, voltages may be altered either up or down in accordance with the desired time in which to run the gel. "Typical voltage" is a reflection of a higher voltage used to decrease running times that still gives an acceptable resolution of fragments.

Caution: it is possible to superheat agarose solutions when they are prepared in a microwave oven. Be very careful that the molten agarose does not froth up out of the flask when preparing the gel.
Caution: EthidiumBromide is a known carcinogen.

Hi Bob, sorry to hear of your troubles with our eeredar, I agree it really is a good little device. Sorry to lose you to Kobo though. The lack of tech support troubles me and I do appologize for their lack of communication. Truly unacceptable! Thanks for bringing this to my attention. I will bring your case up to our Manager over there as we are always looking to improve our processes although its never good when its at the expense of a customer. Thanks again, Greg
