A mixture of three proteins was subjected to ion exchange chromatography using CM-cellulsoe as the stationary phase. The elution buffer had a pH of 7.5. Proteins were eluted by increasing the ionic strength of the buffer. Predict the order of elution of the following proteins: Pepsinogen, pI = 1 Cytochrome c, pI = 10.6 Myoglobin, pI = 6.8
