Needless to say, unbiased reviews of products on corporate websites are often hard to come by. However, if you are in the market for new equipment, Biocompare has a wide selection of unbiased reviews on numerous products that are worth reading before you purchase.

Recently, a scientists at the Cancer Center in the Sanford/Burnham Medical Research Instituted, wrote a review of Bio-Rad Laboratories Trans-blot Turbo System. In his 7 point review, Dr. Dayong Zai provided some useful tips such as the importance of getting rid of all the bubbles prior to transfer and cleaning the system thoroughly once the transfer has finished. The review gave teh Trans-blot Turbo thumbs up for its ease of use, fast transfer times and reproducible results and a thumbs down for the bad smell produced once the transfer has completed.

For some reason, I just can’t get the “Eye of the Tiger” song out of my head! Gotta love this:

Now that you’re in the mood, how about taking a look at another epic battle!

Keeping it constant: A lesson in protein transfer

 :: Posted by American Biotechnologist on 05-22-2012

Power supplies that are used for electrophoresis hold one parameter constant (either voltage, current, or power). The PowerPac™ HC and PowerPac Universal power supplies also have an automatic crossover capability that allows the power supply to switch over to a variable parameter if a set output limit is reached. This helps prevent damage to the transfer cell.
During transfer, if the resistance in the system decreases as a result of Joule heating, the consequences are different and depend on which parameter is held constant.

Transfers Under Constant Voltage
If the voltage is held constant throughout a transfer, the current in most transfer systems increases as the resistance drops due to heating (the exception is most semi-dry systems, where current actually drops as a result of buffer depletion). Therefore, the overall power increases during transfer, and more heating occurs. Despite the increased risk of heating, a constant voltage ensures that field strength remains constant, providing the most efficient transfer possible for tank blotting methods. Use of the cooling elements available with the various tank blotting systems should prevent problems with heating.

Transfers Under Constant Current
If the current is held constant during a run, a decrease in resistance results in a decrease in voltage and power over time. Though heating is minimized, proteins are transferred more slowly due to decreased field strength.

Transfers Under Constant Power
If the power is held constant during a transfer, changes in resistance result in increases in current, but to a lesser degree than when voltage is held constant. Constant power is an alternative to constant current for regulating heat production during transfer.
