maintained Protocols

Category: Cell Culture Protocols: Sterile Technique Protocols

This unit describes some of the ways that a laboratory can deal with the constant threat of microbial contamination in cell cultures. A protocol on aseptic technique is described first. This catch-all term universally appears in any set of instructions pertaining to procedures in which noncontaminating conditions must be maintained. - [Read Aseptic Technique for Cell Culture Protocol]

Category: Microscopy Protocols: Live-Cell Imaging Protocols

Specimen chambers have had many designs published over the years describing systems that offer excellent optical properties while allowing specimens to be maintained for varying amounts of time. Ranging in complexity from the simple preparation of a sealed coverslip on a microscope slide to sophisticated perfusion chambers that enable tight control of virtually all environmental variables culture chambers are designed to to allow living specimens to be observed with minimal invasion at high res. - [Read Culture Chambers for Live-Cell Imaging]

Category: Yeast Protocols: Yeast Protein Protocols: Yeast Protein Protein Interactions Protocols

This procedure capitalizes on the asexual/sexual reproductive cycle of yeast cells. Laboratory yeast strains can be maintained indefinitely by asexual reproduction as one of two haploid mating types, MATa or MAT{alpha}. - [Read Genome-Wide Analysis of Protein-Protein Interactions Using a Two-Hybrid Array]

Category: Tetrahymena Protozoa Protocols

Long-term storage of unfrozen Tetrahymena is convenient when a laboratory is not using the cells frequently; however, cells maintained under these conditions often take a couple of days of incubation in culture medium to recover. - [Read Long-Term Storage of Unfrozen Tetrahymena Cultures in Soybean Medium Protocol]

Category: Bacterial Cell Culture Protocols: Bacterial Stocks Protocols

Plasmid (pUC series) containing genomic DNA fragments are maintained in E. coli strain DH5aTM. The E. coli cultures are routinely cultured at 37 C on Luria-Bertani (LB) agar on or in LB broth containing Ampicillin (30 µg/ml) or Carbenicillin (50 µg/ml broth, 100 µg/ml agar). E. coli strains are usually preserved in stab agar or glycerol for mid-term storage and lyophilized for long-term storage. - [Read Maintenance of Probes in Bacteria Including Escherichia coli Protocol]

Category: Laboratory Model Organisms Protocols

Protocol describes the preparation of stocks of marine hypotrichs for long-term storage. Marine euplotids are maintained by serial passage of tube stocks. - [Read Maintenance of Stocks of Marine Hypotrichs Protocol]

Category: Plant Biology Protocols: Plant Tissue Culture

Plant Tissue Culture - Laboratory protocol for micropropagation from stem tip, node, meristem, embryo or seed. Includes forum maintained by the National ... - [Read Open Directory - Science: Biology: Botany: Tissue Culture]

Category: Tetrahymena Protozoa Protocols

A number of methods can be used for storage of unfrozen Tetrahymena cultures in the laboratory. Cells that are maintained using the short-term storage are described in this protocol. - [Read Short-Term Storage of Tetrahymena Cultures Protocol]
