Detection of Mycoplasma in Mammalian Cell Cultures Using Fluorescence Microscopy Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/1/pdb.prot4351

Category: Cell Culture Protocols: Cell Culture Contamination Prevention and Removal Protocols

Protocol describes a method for mycoplasma detection using Hoechst 33258, a fluorescent dye that stains DNA. Staining of particulate DNA matter around the cell nucleus (on the cell surface or in the cytoplasm) is indicative of mycoplasma contamination. - [Read Detection of Mycoplasma in Mammalian Cell Cultures Using Fluorescence Microscopy Protocol]

Fractionation of Vacuolar and Subvacuolar vesicles and Vacuole and Cytoplasm-to-Vacuole Targeting - http://www.axis-shield.com/densityhome/optiprep/S29.pdf

Category: Cell Organelle Protocols: Subcellular Fractionation Protocols

Fractionation of (a) vacuolar and subvacuolar vesicles and (b) vacuole and cytoplasm-to-vacuole targeting (Cvt) vesicles from yeast spheroplasts in a pre-formed discontinuous iodixanol gradients. Protocol includes: Formation of yeast spheroplasts; Isolation and vesiculation of the vacuoles; Separation of the vacuolar and subvacuolar vesicles; Separation of vacuoles and Cvt vesicles from a yeast spheroplast lysate. - [Read Fractionation of Vacuolar and Subvacuolar vesicles and Vacuole and Cytoplasm-to-Vacuole Targeting]

Microinjection of Protein Samples Protocol - http://www.cshprotocols.org/cgi/content/abstract/2007/1/pdb.prot4657

Category: Microinjection Protocols: Microinjection of Proteins Protocols

This protocol describes a method for microinjecting proteins into the nucleus or cytoplasm of adherent cells. Microinjection equipment can be obtained from a number of suppliers; this protocol has been used with the Narishige IM-200 air pressure regulator and the Leitz micromanipulator. Using this system, it is possible to microinject a constant volume within a 50% difference among cells. - [Read Microinjection of Protein Samples Protocol]

Time-Lapse Cinematography in Living Drosophila Tissues: Preparation of Material - http://www.cshprotocols.org/cgi/content/abstract/2006/29/pdb.prot4602

Category: Microscopy Protocols: In Vivo Imaging Protocols

Sophisticated fluorescence microscopy methods & equipment, now allow cellular events to be studied at high resolution in living material. The studying of living fly tissues presents unique difficulties in keeping the cells alive, introducing fluorescent probes, & imaging through thick hazy cytoplasm. This protocol outlines the preparation of major tissue types amenable to study by time-lapse cinematography and different methods for keeping them alive. - [Read Time-Lapse Cinematography in Living Drosophila Tissues: Preparation of Material]
