Detergent Purification of Membrane Proteins01:18

Detergent Purification of Membrane Proteins

6.3K
Detergents are used to purify the integral proteins of the membrane. The hydrophobic portion of the detergent can replace membrane phospholipids while solubilizing the membrane proteins. When detergent monomers reach a specific concentration in a solution called critical micelle concentration (CMC), they form micelles. Above CMC, the concentration of the detergent monomers remains in equilibrium with the micelle. The number of detergent monomers present in the CMC varies for each detergent, and...

Resumen

Este estudio presenta un dispositivo de fluidos para purificar coloides como liposomas de biopsias líquidas utilizando difusioforesis. El recubrimiento de polímero Pluronic previene eficazmente la adsorción de proteínas, lo que permite el aislamiento eficiente de biomarcadores de vesículas extracelulares para el diagnóstico temprano de enfermedades.
