Category: Microscopy Protocols: Live-Cell Imaging Protocols

Manual measurement and manipulation of the cell surface requires access to the cells, usually in an open chamber. Temperature-controlled chambers or stage inserts are preferred for maintaining physiological activity during the experiment. For example, heated culture dishes with coverslip glass bottoms (Bioptechs) permit high-resolution fluorescence microscopy of living cells during force application. - [Read Chambers for Examination of Live Cells under Mechanical Stress Protocol]

Category: Cell Culture Protocols: Insect Cell Culture Protocols

Insect cell cultures are now commonly used in insect physiology, developmental biology, pathology, and molecular biology. As the field has advanced from methods development to a standard procedure, so has the diversity of scientists using the technique. This paper describes methods that are effective for maintaining various insect cell lines. The procedures are differentiated between loosely or non-attached cell strains, attached cell strains, and strongly adherent cell strains. - [Read Methods for Maintaining Insect Cell Cultures]

Category: Plant Biology Protocols: Plant DNA RNA Isolation Protocols

Protocol is based on the standard Trizol protocol for the purification of RNA from animal cells using Trizol (Purification of RNA from Animal Cells using Trizol). In this version, adapted for use with plant tissues, a high-salt isopropanol precipitation step has been added to precipitate RNA selectively, while maintaining polysaccharides and proteoglycans in solution. - [Read Preparation of RNA from Plant Tissue Using Trizol]
