(0)

Test (Gel Filtration Chromatography) The gel filtration chromatography that is also known as the size-exclusion chromatography seeks to separate the molecules based on their sizes. The stationary phase is made of the porous beads that have a well-defined pore size. The stationary phase has a fractionating range meaning that the molecules can be separated by different molecular ranges depending on their sizes. This experiment utilizes protein molecular mass ranges of between 1000 and 50000 as such 6-75 Sephadex is also applied. The molecules that are small in size can fit into the porous beads and can be said to be included. On the other hand, the more important molecules cannot fit into the dots and...
