lysed Protocols

Category: Reporter Gene Assays: Luciferase Assay Protocols

In this protocol, cells transfected with a luciferase reporter plasmid are lysed in a detergent-containing buffer. Luciferase in the extract catalyzes an oxidation reaction in which D-luciferin is converted to oxyluciferin, with production of light at 556 nm that can be quantified in a luminometer. - [Read Assay for Luciferase in Extracts of Mammalian Cells Protocol]

Category: Immunology: Immunoprecipitation Protocols: Chromatin Immunoprecipitation Protocols

Protocol describes the use of chromatin immunoprecipitation technology (ChIP) to analyze interactions of proteins or protein complexes with DNA in vivo. In this approach, the material is fixed with formaldehyde to preserve DNA-protein and protein-protein associations, the cells are lysed, and the chromatin is cut and solubilized. The chromatin suspension is immunoprecipitated with an antibody against the protein(s) of interest, and the coimmunoprecipitated DNA fragments are analyzed. - [Read Chromatin Immunoprecipitation (ChIP) of Protein Complexes Protocol]

Category: Cell Biology and Cell Culture: Flow Cytometry Protocols: Cell Sorting Protocols

Protocol describes how monocytes can be sorted from a lysed whole blood sample, and that cytospin preparations can be made for examination by light microscopy. - [Read Enrichment Of Monocytes For Morphological Study Protocol]

Category: Immunology: Immunoprecipitation Protocols: Immunoprecipitation of Radiolabeled Cells Protocols

Coimmunoprecipitation is most commonly used to test whether two proteins of interest are associated in vivo, but it can also be used to identify novel interacting partners of a target protein. In both cases, the cells, which may have been labeled with [35S]methionine, are harvested and lysed under conditions that preserve protein-protein interactions. The target protein is specifically immunoprecipitated from the cell extracts, and the immunoprecipitates are fractionated by SDS-PAGE. - [Read Identification of Associated Proteins by Coimmunoprecipitation Protocol]

Category: Bacterial Cell Culture Protocols

In this protocol, bacterial cells are lysed by being subjected to short, intense treatments with ultrasound, which breaks the cell walls and shears the DNA into sizes that will not affect the viscosity of the samples. Note that this method causes some denaturation of the samples. The resulting lysate is ready for preclearing. - [Read Immunoprecipitation: Lysing Bacteria by Sonication Protocol]

Category: Signalling Signal Transduction Protocols

Protocol describes a competitive ligand binding assay for cortical neurotrophin receptors. Following binding in the presence of competitor, the bound radiolabeled ligand is cross-linked to the receptor. The cells are lysed and the ligand-receptor complexes are immunoprecipitated using a pan-trk (tyrosine kinase receptor) antibody. Protocol includes:Preparation of Cortical Tissue for Competitive Crosslinking, Competitive Binding, Crosslinking Ligand to Receptor, Lysis and Immunoprecipitation etc - [Read Protocol for Competitive Ligand Binding to Cortical Receptor using Crosslinking]

Category: DNA Protocols: cDNA Library Protocols

A cDNA library constructed in a plasmid expression vector of the pUC, pUR, or pEX series is plated on agar medium and then replicated onto filters, which are transferred to plates containing IPTG. After 2-4 hours of induction, the colonies are lysed with chloroform and then screened with appropriate antibodies. - [Read Screening Expression Libraries Constructed in Plasmid Vectors Protocol]
