FITC (Fluorescein isothiocyanate), introduced in 1942, is essential in biochemical research for labeling proteins and antibodies. Its reactive isothiocyanate group forms stable bonds with primary amines, enabling the creation of highly fluorescent derivatives. This has revolutionized staining techniques, though optimal labeling varies with molecular weight to avoid issues like quenching or nonspecific binding.

The blood-brain barrier (BBB) is a highly selective, semipermeable border that separates the circulating blood from the brain and extracellular fluid in the central nervous system (CNS). Composed of endothelial cells with tight junctions, astrocyte end-feet, and pericytes, the BBB plays a crucial role in maintaining the brain’s microenvironment. It restricts the passage of pathogens, toxins, and large or hydrophilic molecules while allowing essential nutrients and gases to pass through.

Diagnosing acute pancreatitis remains challenging due to high error rates in standard clinical panels. This complexity is heightened by macroamylasemia which is characterized by the presence of elevated levels of macroamylase in the blood and can lead to falsely elevated amylase results unless specifically ruled out. This article discusses the general challenges in diagnosing pancreatitis and specifically highlights how the gel permeation chromatography (GPC) method using Blue Dextran 2000 (BD2000) can be used to rule out pancreatitis by accurately measuring macroamylase levels.
