Safe storage of lipid-membranes for protein lipid overlay assay

[Kyle Legate]

Good day!

I am preparing to perform a protein lipid overlay assay as described by 
Dario Alessi et al in the following article:

I would like to prepare several membranes at one time to avoid the 
tedium of making serial dilutions of lipid whenever I want to do the 
experiment, and I would like opinions on the best way to store them to 
keep them fresh? Individually packaged under argon? Floating in blocking 
buffer+azide? Stacked in between sheets of blotting paper? Another 
clever solution?

Thanks in advance for your ideas.

Kyle
