Web蛋白质定量 (LOWRY法) Lowry法是双缩脲法和福林酚法的结合与发展，其原理是：蛋白质溶液用碱性铜溶液处理，形成铜-蛋白质的络合盐，再加入酚试剂后，除使肽链中酪氨酸、 … WebThe Folin phenol reagent method consists of two steps. The first step is that under alkaline conditions, the protein reacts with copper to form a protein copper complex. The second step is that this complex will reduce Folin reagent to produce dark blue, and the color depth is proportional to the protein content.
