How does the Binding Buffer assist in the process of GFP purification?

• A. It raises the temperature of the solution
• B. It decreases the salt concentration
• C. It enables hydrophobic proteins to bind
• D. It stabilizes the GFP structure

Answer: (C)

The Binding Buffer plays a crucial role in the purification of GFP by facilitating the binding of hydrophobic proteins, including GFP, to the affinity matrix used during purification. The buffer is designed to create conditions that promote the interaction between the hydrophobic regions of the protein and the hydrophobic environment of the binding medium, such as beads or chromatography resins that are used in the purification process. This hydrophobic interaction is essential because it allows the GFP to adhere to the matrix, effectively separating it from other components present in the solution. Once the GFP is bound, washing and elution steps can be conducted to purify the protein based specifically on those interactions, leading to a higher purity of the target protein. The buffer's composition and pH are optimized to ensure that GFP maintains its functional conformation while effectively engaging in these necessary interactions for purification.
