Quenching trypsin
WebAnd similar trends were found in the colorant-trypsin system. Generally, the quenching rate constants of the fluorescent complex are supposed to change with different temperatures [23]. Higher temperatures can promote the process of diffusion, and then a larger amount of collision quenching could occur.
