Enzymatic Flow Reactor for Immobilized Enzyme Processes

The Enzymatic Flow Reactor comes ready for enzyme immobilization. The first step is to incubate the desired enzyme with, for example, N-succinimidyl 3-(2-pyridyldithio)propionate (SPDP), which is a crosslinking agent that reacts with the free amino groups on the enzyme surface. A solution of the SPDP-modified enzyme is then
