Category: Microscopy Protocols

The atomic force microscope (AFM) is one of the most powerful tools for determining the surface topography of native biomolecules at subnanometer resolution. The AFM can also provide insight into the binding properties of biological systems. In order to determine the specific interaction between two kinds of molecules (e.g., avidin and biotin). Includes information on principle of AFM and application of AFM. - [Read Imaging, Measuring and Manipulating Native Biomolecular Systems with the Atomic Force Microscope]

Category: Primary Cell Isolation and Culture Protocols

There are several manual methods that can be used to perform tissue microdissection. Techniques using hand-held tools as well as mechanical micromanipulator-based approaches have been described. However, speed and precision are the most important parameters and any method that achieves these is adequate. Investigators should also expect to invest time initially by practicing on 10 to 20 cases to begin to feel comfortable with the technique. - [Read Manual Microdissection]

Category: Primary Cell Isolation and Culture Protocols: Laser Capture Microdissection Protocols

Human tissues are comprised of multiple interacting cell populations in a complex three dimensional arrangement with each cellular phenotype determined by a unique profile of mRNA and protein expression. Before microdissection techniques were developed, the only analysis tools for phenotypic studies were primarily immunohistochemistry and in-situ hybridization. While useful, these tools are limited to single gene analysis and, in general, do not allow qualitative studies. - [Read Microdissection Overview]

Category: Cell Biology and Cell Culture: Cell Viability Protocols

The latest generation of Promega cell-based assays includes luminescent and fluorescent chemistries to measure markers of cell viability, cytotoxicity and apoptosis, as well as to perform reporter analysis. Using these tools researchers can investigate how cells respond to growth factors, cytokines, hormones, mitogens, radiation, effectors, compound libraries and other signaling molecules. The protocols provided are guidelines for multiplexing cell-based assays & are intended as starting points. - [Read Multiplexing Cell Viability Assays Protocols]
