Implication

Experimental study demonstrates enhanced solubilization of hydrophobic proteins using urea, thiourea, and detergent mixtures, indicating improved yields in two-dimensional gel electrophoresis.

Key Points

To overcome severe quantitative protein loss during immobilized pH gradient isoelectric focusing by improving denaturing solubilization protocols.
Separated poorly soluble membrane and nuclear proteins using high-resolution two-dimensional (2-D) gel electrophoresis with immobilized pH gradients.
Tested various denaturing solutions containing combinations of chaotropes (urea, thiourea) and detergents (both nonionic and zwitterionic).
Evaluated solubilization efficacy on microsomal proteins, nuclear proteins, and aggregation-prone tubulin.
Denaturing solutions containing a combination of urea, thiourea, and mixed detergents achieved the greatest enhancement in protein solubilization.
Thiourea-based mixtures successfully reduced protein losses and prevented aggregation during the separation of microsomal, nuclear, and tubulin samples.
