Lysis in the sucrose-containing Buffer ("Mito-Buffer") is supposed to prevent accidential disrupture of the mitochondria to prevent the leakage of mitochondrial proteins (such as cytochrome c) into the cytosol. Celldeath.de - [Read Gentle lysis of mammalian cells for cytochrome c release assay]

Category: Western Blot Protocols: Antigen Detection Methods Protocols

The blot is blocked to prevent nonspecific adsorption of the immunological reagents.  Antibodies are then bound to the proteins immobilized on the membrane, and the antigen is detected by labeling the antibodies with conveniently identified tags.  Common labeling methods for chemiluminescent detection include anti-immunoglobulin antibody-coupled enzymes such as horseradish peroxidase, which catalyzes the oxidation of luminol and in turn releases light. - [Read Immunoblotting: Antigen Detection Using Chemiluminescence Protocol]

Embryonic stem cells are usually grown on a layer of mitotically inactivated primary mouse embryonic fibroblasts to promote growth and prevent differentiation. Boris Greber - [Read Isolation and handling of primary mouse embryonic fibroblasts (MEFs)]

Category: Cell Culture Protocols: Sterile Technique Protocols

This unit on sterility in the tissue culture environment describes methods for sterilization of liquid and dry goods used for tissue culture and filtration of liquids to prevent contamination of cultures. - [Read Sterilization and Filtration Protocol]

Category: Antibody Protocols: Antibody Handling Protocols

Ascitic fluid from B-cell-derived tumors is an extremely concentrated solution of specific antibodies. Ascitic fluid is often stored at -70ºC to prevent proteolytic degradation. - [Read Storage of Ascitic Fluid Protocol]
