Abstract
A method of forming a stable protein complex comprising: providing aqueous protein complexes, wherein the protein complexes are one or more of photosystem I complex from spinach, photosystem II complex from spinach, chlorophyll antennae, thylakoids, bacteriochlorophylls, chlorosomes, and photosystems from green algae, cyanobacteria, and plants; cationizing the aqueous protein complexes by the addition of stoichiometric amounts of a crosslinker in the presence of a coupling reagent; titrating the cationized protein complexes with a counter anionic polymer until the protein cation/anion pair solution becomes negative by zeta potential measurement, to create at least one antibody cation/anion pair in aqueous solution. The protein complexes cation/anion pair solution may be lyophilized to remove all of the water, forming a lyophilized solid. The lyophilized solid may be heated until a protein complex ionic liquid is generated. The cationized protein complexes may be purified from excess coupling reagents by dialysis in water.
