研究了平均孔径分别为28埃和45埃的MCM-41/28和MCM-41/45两种不同材料对细胞色素c的吸附和活性。蛋白质吸附前后的氮气吸附/脱附等温线和蛋白质被吸附后的过氧化活性曲线表明，蛋白质被吸附到介孔中并保持活性。一系列不同的蛋白质在MCM-41/28和45上的吸附表明了蛋白质性质如何影响吸附。
The adsorption and activity of cytochrome c onto two different MCM-41 materials, MCM-41/28 and MCM-41/45 with average pore diameters of 28 and 45 Angstrom respectively, is presented. Nitrogen gas adsorption/desorption isotherms before and after protein adsorption, and peroxidative activity profiles of the adsorbed protein demonstrate that the protein is adsorbed into the mesoporosity and remains active. The adsorption of a range of different proteins onto both MCM-41/28 and 45 shows how protein properties affect adsorption.
