- Glarger parts of protein
- Hparts of protein where PI (protein) >Ph (buffer)
2Gel filtration separates proteins by [blank_start]size[blank_end].
- Asize
3Ion exchange chromatography separates protein(s) by [blank_start]charge[blank_end].
- Acharge
4Do larger or smaller proteins/parts of protein flow through gel filtration first?
- Alarger
- Bsmaller
5Anion exchanger means that it removes [blank_start]anions[blank_end] from protein mixture so that means the resin must be decorated with [blank_start]positively[blank_end] charged moieties
- Aanions
- Bpositively
