• Molecular Weight Determination by GPC
Molecular weight determination by GPC is a chromatographic technique used for analyzing and characterizing the molecular weight distribution of polymers. It is based on the principle of size exclusion, where solute molecules are separated by the screening effect of the stationary phase's porous material. High molecular weight solutes, which cannot penetrate the pores, elute earlier, while low molecular weight solutes, which are able to enter and remain trapped in the pores for longer, elute later. Thi......

Native protein analysis is a technique used to study the functions and characteristics of proteins in their natural state. This method preserves the native conformation and interactions of proteins, enabling scientists to directly observe and measure their biological activity. Unlike analyses conducted under denaturing conditions, which often disrupt the protein’s natural structure and may lead to the loss of functional properties, native protein analysis offers distinct advantages in studying protein......
