What is the purpose of buffer exchange in downstream processing?

Step 1: Understand that buffer exchange is a process used in biochemistry.
Step 2: Know that buffers help maintain a stable pH level in solutions.
Step 3: Realize that different purification steps require specific pH and ionic strength.
Step 4: Learn that buffer exchange replaces the current buffer with a new one that has the desired pH and ionic strength.
Step 5: Recognize that this adjustment helps improve the efficiency of the purification process.
