Western Blot Blocking: Tips and Tricks
Wednesday, February 22, 2017

Western blotting is an immunodetection technique used to first separate proteins by gel electrophoresis then to transfer those separated proteins from the gel matrix onto a secondary, more durable matrix, most commonly polyvinylidene difluoride (PVDF) or nitrocellulose. ..

Cell Lysis: 5 Common Cell Disruption Methods | G-Biosciences
Tuesday, February 14, 2017

When working on proteins, your sample biological materials should first be homogenized to ensure proper solubilization and extraction. This can be a challenge if you are trying to extract plant proteins because their tissues contain significant amounts of proteases, phosphatases and glycosidases ... ..

Plant vs Animal Cells: Break the Cell Wall with Lytic Enzymes
Tuesday, January 31, 2017

Extracting proteins from plants is not the same as extracting proteins from animal sources. There is a very different set of factors that you will need to consider in order to properly process plant proteins. This post explores some of the key ways in which plant-based protein extraction differs ... ..

Western blot: Constant current or constant voltage; which is best?
Friday, January 20, 2017

The choice of constant current or constant voltage will depend on several different factors that must be taken into consideration for each Western transfer test. The level of heat, duration of the test, type of proteins, the size of the transfer, and the rate of transfer will all be affected... ..
