A rapid method for assessing lipid:protein and detergent ...
The importance of monitoring detergent concentration changes during simple procedures, such as the concentration of a membrane protein by ultrafiltration, is demonstrated. This analytical tool has been used to rapidly establish protocols for minimizing lipid and detergent levels in solubilized membraneprotein samples.

Amphipathic Polymers: Tools To Fold Integral Membrane ...
Among the major obstacles to pharmacological and structural studies of integral membrane proteins (MPs) are their natural scarcity and the difficulty in overproducing them in their native form. MPs can be overexpressed in the nonnative state as inclusion bodies, but inducing them to achieve their functional threedimensional structure has proven to be a major challenge.

Membrane proteins rely on their interaction with membrane lipids to uphold its structure and maintain its functions as a protein. For membrane proteins to purify and crystallize, it is essential for the membrane protein to be in the appropriate lipid environment. Lipids assist in crystallization and stabilize the protein and provide lattice ...

Protein Structure Prediction Despite improvements on both experimental techniques and computational prediction methods for small and medium sized proteins, structure elucidation and prediction for larger proteins remains a major challenge. We are developing a structure prediction algorithm that incorporates data of various experimental techniques but also to be used as a standalone tool.
