4. Estudos de caso
Estudo de caso 1: Extração de proteínas de membrana
A research team used Chapso (1% w/v) in 20 mM Tris-HCl buffer (pH 7.4) to solubilize G-protein coupled receptors (GPCRs) from mammalian cell membranes. The solution was centrifuged at 100,000×g for 1 hour, yielding active receptors for crystallization trials.
Case Study 2: 2D Gel Electrophoresis
Chapso was incorporated into a sample buffer (2% w/v) for resolving mitochondrial proteins. The detergent improved protein solubility without interfering with isoelectric focusing, enabling clear spot detection in Coomassie-stained gels.
