Thank you for these great videos! My biotech LAB classes are only virtual right now (which is stupid) and we are not learning how these techniques actually work, but with your videos I will be ready to get a job.

Thank you you explained that 2 substances are in ion column...subs A directly attached to resin and subs B that is bound to it by an ionic bond and that B is the one to be exchanged with the analyte...thank you for revealing this

Another rule, is that you should use a pH at least 1 unit away from the PI in order to make sure the protein/peptide is completely protonated/deprotonated. So, if the PI is 2, and the pH is 2.3, you will probably not get good retention of your target peptide.

if the ph of the medium is lower than the pI of the protein, then the protein will be protonated and hence will be positively charged. If the ph is higher than pI then less proton are available in the medium and so the protein will lose its hydrogens from the side chains and become negatively charged.

much thanks for the clear illustration! One more question I have is that how the exchange occurs between the two elements of same charges ( B and C) in other way what is the reason behind the settlement of the protein of interest (C) that we want to eliminate and having the exchanged element (B) in our outflow??
@reemmahmoud63424 жыл бұрын
It can be because subs A has more affinity to C than B...or because the concentration of C is much higher than B

When the Ph of the medium is less than the PI of the protein .. than the protein is definitely positively charged

I’ll probably think it’s because it has less binding groups attached to the stationary phase coupled with its having the lowest molecular weight.

If pka is 5...then what method should be used for chromatography and what ph should be used for elution
@chrischukwuma64693 жыл бұрын
I would use anion exchanger( positively charged stationary phase), adjust my medium PH above the pka to deprotonate and make my Protein negative, I wouldn't want a lower pH that will make my Protein positive as there are higher chances of having other Proteins that are stable around that pH that can bind alongside my Protein. For elution, I will gradually decrease the inonic strength of my Buffer.

i want to test bromate by my drinking water then how i do it?
@biomedicalandbiologicalsci49896 жыл бұрын
You need first to isolate bromate from drinking water using anion exchange chromatography, then you elute bromate using salting out. And then you can detect the presence of Bromate using a type of spectroscopy or UV light detector. There are machines nowadays that combine all these steps together, they are specially designed to detect bromate in drinking water.
