Preparation and Characterize of Konjac Glucomannan-Based Protein Molecularly Imprinted Polymer
Objective: To prepare a novel molecularly imprinted materials for protein recognition. Methods: Konjac glucomannan was used as fundamental materials, after swollen, added 3-Chloro-1,2- epoxypropane and glycerol cross-linked for 3 h at 40 °C. Then added bovine serum albumin (BSA) solution, agitated 1 h at room temperature. Natural dried. Results: After eluted, the imprinted efficiency of the imprinted membrane were (59.27±3.53) % (n=6) with blank membrane as control. The adsorption rate increased from 2 h to 20 h, and reached saturation at 22 to 24 h. The selectively recognition experiment indicated the BSA imprinted membrane have significant selectively recognition abilities for the template protein. Conclusions: konjac glucomannan-based imprinted membrane shows great possibilities to be a promising material for protein molecularly imprinted recognition.
