Brilliant! I am not a native speaker but i really got it well. But i have a question. I wonder if someone can regain the proteins in a 100% purity or a near percentage purity by using this method. Thank you sir for these wonderful lectures.
You are the best. How about separation of polysaccharides? And I'd like to also emphasise that some molecules bear same color, in that case what will one do about timing?

So on a SEC machine, buffer is supposed to be constantly pumped through the system. What is the consequence if there is not a consistent flow of the buffer? This happened during a portion of our experiment and some overlapping peaks showed on the chromatogram.

Why doesn't the protein of interest dissolve back into the solution in the baggie, and do the other proteins that were in the baggie go through the semipermeable membrane? And if they do then why wouldn't the protein of interest also go through since salt concentration in the baggie is going down making it soluble in water?

What is the difference between Gel Filtration Chromatography and Size Exclusion Chromatography?
@manjitrana3608
6 жыл бұрын
Basically the names are used interchangeably. However, to be more specific Gel Filtration Chromatography is one of the methods of Size Exclusion Chromatography. Size Exclusion Chromatography is an umbrella term. Other methods include Gel Permeation Chromatography where you use organic solvent as a mobile phase rather than aqueous solvent as in Gel Filtration Chromatography. Hope that helps!

Yes, the gel has a fractionation range. Proteins within this range will separate, while proteins outside this range will not. The 3 large proteins in your question would elute together as one molecule and therefore at the same time. Similarly, proteins that are too small to separate will fail to separate and also elute as a single molecule. However, if you have 3 proteins that are too large and 3 proteins that are too small, the 3 proteins that are too large will elute faster than the 3 that are too small, even though they are all outside the fractionation range.
