another form of interaction

the one covered was size exclusion (based on size; fact protein as they move, they’re restricted differentially based on size

ion exchange chromatography

there are ions exchanged here

• chemistry where there is somse sort of interacting via bonding (electrostatic bonding between negative and positive charges)
• the keyword is reversible
  • you have to move it from there

medium could be resin

• positive charge binds to a negative charge stationary phase

in here

R → resin (material that is solid)

attached to it is a ligand through a linker

linker → is attached to a positively or negatively charged functional group (head group) at a certain pH [Y]
