Emulsiones agua en aceite: Un nuevo sistema para el ensamblaje de las proteínas de unión de clorofila-solubles en agua con pigmentos hidrófobos

Overview

This manuscript describes a high-throughput method for assembling water-soluble proteins with hydrophobic pigments using water-in-oil emulsions. The technique facilitates the incorporation of water-insoluble chlorophylls into binding sites of recombinant proteins, enabling detailed studies of chlorophyll-protein interactions.
