What buffer is used in the IFCC recommended Bowers-McComb method for ALP?

• A. Tris buffer
• B. 2 Amino-2-Methyl-1-propanol
• C. Sodium bicarbonate
• D. Phosphate buffer

Answer: (B)

In the IFCC recommended Bowers-McComb method for alkaline phosphatase (ALP) measurement, the buffer used is 2-Amino-2-Methyl-1-propanol, often referred to as AMP or AMAP. This buffer is particularly effective in providing the optimal pH environment that stabilizes the enzyme during measurement, which is crucial for accurate assay results. The use of this specific buffer helps in maintaining the alkaline pH required for the activity of ALP, thus enhancing the overall sensitivity and specificity of the assay. The choice of buffer is significant in enzymatic assays, as it can affect enzyme activity, stability, and the overall reaction kinetics. While other buffers like Tris, sodium bicarbonate, and phosphate buffer are commonly used in various biochemical applications, they do not provide the same advantages as AMP in the context of the Bowers-McComb method for ALP. Each buffer has its limitations regarding pH range and potential enzyme interaction, making AMP a preferred choice for this particular method.
