Fabrication of Ovalbumin–Phospolipid Thin Film with Minimal Protein Aggregation by Different Self-Assembly Methods
This paper describes a new approach for the preparation of Ovalbumin (OVA)-phospholipids (DPPC) thin film, where we minimize the aggregation among protein molecules. A comparative study on the films fabricated by self-assembly (SA) of protein-lipid mixed vesicle on hydrophilic glass substrate and SA of protein alone on prefabricated Langmuir-Blodgett (LB) film of DPPC is being carried out. Far UV circular dichroism spectroscopy, FTIR analysis of amide bands and surface morphology study by FE-SEM imaging is being used to examine the extent of conformational change as well as aggregation of protein. Protein-lipid thin film prepared by the former method provides the secondary structure of individual OVA molecules with increment of α-helical segments. In this process, OVA molecules do not show larger aggregation among themselves. However, in the second method, we find unfolded larger aggregated structure of OVA with increment of β-structure of OVA.
