For both biological and economical reasons, it is important to eliminate mycoplasmas from cell cultures being used for basic research, diagnosis, and biotechnological production. The most commonly used method for elimination, inactivation, or suppression of mycoplasmas in cell cultures is treatment with antibiotics. In general, antibiotic therapies do not result in long-lasting, successful elimination. Also, the cytotoxic properties of antibiotics can cause undesirable side effects on cells. - [Read Mycoplasma Elimination Reagent Protocol]

Protocol for oligonucleotide-directed mutagenesis by elimination of a unique restriction site (USE mutagenesis). - [Read Oligonucleotide-directed Mutagenesis by Elimination of a Unique Restriction Site (USE Mutagenesis)]

Category: Immunology: Mononuclear Cell Isolation Protocols: T-Cell Isolation Protocols

Protocol describes removal of T cell subsets by cytotoxic elimination using CD-specific antibodies. Describes the complete removal of T cells from lymphocyte preparations based on the presence of the glycoprotein Thy-1 on the cell surface of T lymphocytes. Cytotoxic elimination is employed; however, Thy-1-specific antibodies are used rather than MHC class II-specific antibodies so that T cells are eliminated rather than B cells and accessory cells. - [Read T Cell Depletion by Cytotoxic Elimination Protocol]

Category: Immunology: Mononuclear Cell Isolation Protocols: T-Cell Isolation Protocols

Describes T cell enrichment using cytotoxic antibodies, and also describes the depletion of T cells and their subpopulations using the same approach. In the latter unit, T cell surface markers (Thy-1, CD4, and CD8) are targeted by the cytotoxic antibodies. - [Read T Cell Enrichment by Cytotoxic Elimination of B Cells and Accessory Cells Protocol]
