Sentence examples for membrane is difficult from inspiring English sources

In fact especially their extraction from the respective membrane is difficult and often goes along with losses in yield.

Moreover, UI in sPI/xUI composite membrane is difficult to be brought out by the vapor due to the existence of long hydrophobic moiety, which will improve the stability and lifetime of the membranes in the fuel cells.

Ion channel trafficking to and from the plasma membrane is difficult to study, partly due to the difficulty in extracting pure plasma membrane proteins and the complex steps during vesicle trafficking.

The signal from proteins inserted into the limiting membrane is difficult to detect unless the extent of co-localization with a plasma membrane marker protein is determined.

The exact percentage of different PIPs in the plasma membrane is difficult to determine because of the reversible turnover of PI 4,5 P2 to PI 3,4,5 P3 and other PIP species.
