Sodium Dodecyl sulfate Porosity Gradient Gel Electrophoresis

Polyacrylamide gradient gels also offer greater possibilities for the electrophoretic separation of proteins in the presence of sDs. Porosity gradient gels have a much higher resolving capacity, for example the two chains of haemoglobin of Mr = 15 126 and 15 866 Da, respectively, can be clearly separated in a 3-30% T gradient gel. An 8% T continuous PA-SDS gel does not exhibit this resolving capacity. In sDs porosity gradient gel electrophoresis the use of continuous buffer systems is recommended (Table 11) since partial deloading of SDS-protein complexes has been observed when the gel contained SDS but not the electrode buffer. This results in a confusing multitude of bands.

Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
