Liver sinusoidal endothelial cells (LSECs) are the most abundant non-parenchymal hepatic cell population. They are highly specialized liver endothelial cells that form a barrier to separate hepatocytes and hepatic stellate cells from contacting the blood. In additional to serving as a physical barrier, LSECs have critical physiological and immunological functions. Furthermore, LSECs regulate cell-to-cell crosstalk as chronic liver conditions advance, eventually leading to fibrosis and carcinogenesis.

Thermo Scientific Pierce EDC is a carboxyl- and amine-reactive zero-length crosslinker. EDC reacts with a carboxyl group first and forms an amine-reactive O-acylisourea intermediate that quickly reacts with an amino group to form an amide bond with release of an isourea by-product. The intermediate is unstable in aqueous solutions and so two-step conjugation procedures rely on N-hydroxysuccinimide (NHS) for stabilization. Failure to react with an amine will result in hydrolysis of the intermediate, regeneration of the carboxyl, and release of an N-substituted urea. A side reaction is the formation of an N-acylurea, which is usually restricted to carboxyls located in hydrophobic regions of proteins.

Cetyltrimethylammonium bromide is a phase transfer catalyst ideal for the precipitation of DNA. Hexadecyltrimethylammonium bromide is a bactericidal, cationic detergent. Its activity is neutralized by soaps and anionic detergents (i.e., SDS). Trimethylammonium bromide compounds form insoluble complexes with SDS. It is active at alkaline pH against both Gram positive and Gram negative organisms.

Hepatic stellate cells are responsible for the regulation of extracellular matrix proteins and vascular structure in the liver. They represent approximately 5 to 8% of the cells in the liver and function to maintain homeostasis in the microenvironment of the hepatic sinusoid. They play a critical role in the development of liver fibrosis. When chronic liver damage occurs, hepatic stellate cells are actively synthesizing extracellular matrix proteins such as collagen and other glycoproteins. The accumulation of the extracellular matrix proteins trigger hepatic fibrosis which can lead to cirrhosis.

It recognizes both the free and protein-conjugated (either soluble or cell bound) form of biotin. This mAb is highly specific to biotin and shows no cross-reaction with other structurally related compounds. It has a very high affinity for biotin and is excellent for use in various amplification techniques. In some applications, localization of biotinylated probes with avidin produces unacceptably high background staining. Anti-biotin antibody may be substituted to decrease this noise.

Agarose is a natural polysaccharide isolated from agar or agar-bearing marine algae. Its physical and chemical properties are particularly suited for use as a gel medium for diffusion and electrokinetic movement of biomolecules. Agarose is essentially biologically inert and forms relatively clear, transparent gels. Agarose based gels offer several advantages: High gel strength permits use of low concentrations. The macroporous nature of the gels allows rapid diffusion of high molecular weight molecules. Agarose is Non-toxic. Agarose gels are thermally reversible facilitating sample recovery. Staining and destaining may be done rapidly with minimal background. Because agarose forms macroporous gels that are electrically nonionic, it is an excellent medium for Isoelectric Focusing (IEF). A selection of different formulated agaroses with specific qualities for unique applications are available from MP.
