Complex Problems. The Perfect Solutions.

We offer several solutions for small-scale chromatographic protein fractionation

Fractionation using ultrafiltration of complex protein solutions and separation of unbound or unincorporated label from protein samples are some of the main applications of these centrifugal devices. It is important to note, that this method is also valid to remove cellular debris after cell lysis to partially purify protein product found in the filtrate. This is important because if the two proteins that need to be fractionated from one another were close in size, then it would be impossible to purify the two from one another. More expensive chromatographical methods would have to be used in that instance.


See Laboratory Chomatography for purification strategies of proteins of similar size. Typically products are now ready for further processing or direct use in downstream applications, such as western blotting or ELISA.
