Can you use electrophoresis to separate larger proteins with different pI numbers?

Thanks

5:23.If the -NH2 group deprotonates, there will be a charge of negative 1 on the nitrogen atom and it will not have net charge 0 on it. Hence there is going to be a net charge of negative 1 on Arginine according to the explanation.

HI there!...I have a question.... At the isoelectric point we can find zwitterions, high pH aminoacids and low pH aminoacids???

@temporaryrelief2981

i believe we can find all three ..but in terms of concentration zwitterions will overwhelmingly predominate

Yes you are correct, consider it as two equilibria which both tend towards the production of the zwitterion at the isoelectric point.

how we can use electrodialysis for peptide separation????

Hi, Thank you for the video! I am a bit confused about Arginine being classified as "acidic." According to the Khan Academy videos that I've been using to study for my MCAT, I've been classifying the deprotonated Arginine as a basic, polar aa. Why are we assuming that Arginine is protonated in this case?

You misunderstand. ARginine is not acidic, it is basic. Whether or not it is protonated is related to the pH.
