A large number of methods devoted to the identification of apoptotic cells and the analysis of the morphological, biochemical, and molecular changes that take place during this universal biological process have been developed. Apoptotic cells are recognized on the basis of their reduced DNA content and morphological changes that include nuclear ...

Cell Sensitivity Assays: The MTT Assay
2003The clonogenic assay described in Chapter 2 is not suitable for all cell lines. Many adherent cell lines do not form colonies and clearly it is not applicable to non-adherent cell lines. Furthermore, it is slow and time consuming. This chapter describes an alternative cytotoxicity assay that has a number of advantages when compared with a clonogenic ...

Neoangiogenesis constitutes one of the first steps of tumor progression beyond a critical size of tumor growth, which supplies a dormant mass of cancerous cells with the required nutrient supply and gaseous exchange through blood vessels essentially needed for their sustained and aggressive growth.

The immune system is a complex interactive network. Defects in its function can be characterized broadly as being the result of actual deficiencies in the network or misdirection of normal immunologic functions. The assays that are available to detect deficiencies in the immunologic network barely scrape the surface of the possibilities.

Cellulose is a heterogeneous polysaccharide, and its enzymatic hydrolysis requires endoglucanase, exoglucanase (cellobiohydrolase), and beta-glucosidase to work together. We summarize the most commonly used assays for individual enzymes and cellulase mixture.

Glycoconjugate Journal, 2008
beta-Hexosaminidases (EC 3.2.1.52) are lysosomal enzymes that remove terminal beta-glycosidically bound N-acetylglucosamine and N-acetylgalactosamine residues from a number of glycoconjugates. Reliable assay systems are particularly important for the diagnosis of a family of lysosomal storage disorders, the GM2 gangliosidoses that result from inherited

INTRODUCTIONThe cAMP assay provides a quantitative determination of the efficiency of the functional complementation between pairs of hybrid proteins. cAMP measurements are obtained using ELISA. Commercial radio-immunoassays, or ELISA kits, to assay cAMP can be purchased from various manufacturers. In our laboratory, we use the homemade, less-expensive

Angiogenesis-the formation of a vascular network-is essential for the support of a developing tumor when simple diffusion of nutrients is impossible. The ability of a solid tumor to achieve metabolic needs beyond simple diffusion is dependent on the development of this neovascular network.

INTRODUCTIONThis assay is used for protein quantitation. It is relatively accurate for most proteins, except for small basic polypeptides such as ribonuclease or lysozyme. It is also hampered by detergent concentrations over ~0.2%.

AbstractCyclooxygenase (COX, also known as prostaglandin H2 synthase, PGH2) is one of the most significant enzymes in pharmacology since COX inhibition is the mechanism of action of most nonsteroidal anti‐inflammatory drugs (NSAIDs). There are two forms: COX‐1 is a constitutive form of the enzyme that has been linked to the production of ...
