Protocol for 3/7 assay. Includes: Detection of Caspase-3 and -7 Activities in Cell-Based Assays; Detection of Caspase-3 or -7 Activity Using Purified Caspases. - [Read 3-7 Assay Protocol]
This bioassay utilizes cultured Hepa-lclc7 (Hepa-1) mouse hepatoma cells to assess the CYPlA1-inducing potency or cytotoxicity of pure test chemicals or environmental samples. In the Hepa-l induction test , the CYPlA1-inducing potency of the test sample is detected as increased aryl hydrocarbon hydroxylase (AHH) and 7-ethoxyresorufin O-deethylase (EROD) activities. - [Read CYP1A1-Inducing Potency and Cytotoxicity Test in the HEPA-1 Mouse Hepatoma Cell Line]

Protocol describes how to assay for kinase activity within a polyacrylamide gel, rather than in solution. The advantages to an in-gel assay are that an apparent molecular weight can be assigned to the kinase activity and that multiple kinase activities can be distinguished. Includes protocol hints. - [Read In-Gel Kinase Assay]
MALDI Matrices. Commonly used MALDI matrices for analysis of peptides, proteins, carbohydrates, and nucleic acids using 337 nm or 355 nm UV lasers. All matrices can be used for sample preparation using the Dried Droplet Method whereas only matrices solubl - [Read MALDI Matrices]

Protocol describes a split luciferase complementation assay used to study the interaction of proteins in cells. In the split protein strategy, a single reporter protein/enzyme (firefly luciferase [Fluc]) is cleaved into amino-terminal and carboxy-terminal halves; each half is fused to one of two interacting proteins, X & Y. Physical interactions between the two proteins reconstitute the functional reporter protein, leading to enzymatic activities that can be measured by in vitro or in vivo assay - [Read Split Luciferase Complementation Assay for Studying Interaction of Proteins X and Y in Cells]
