You're using anion exchange chromatography to purify a small globular protein. After passing the mixture through the column, you find that your protein did not "stick" to the resin and flowed right through. What is a plausible reason for this to have occurred? Correct Answer-The pH of the solution is close to the isoelectric point. Oxygen binding that affects the cooperatively of hemoglobin is an example of heterotrophic regulation. Correct Answer-False You have determined that a leucin...
