Protocol for RNA preparation from cultured cells or tissue samples. This protocol has been used to isolate RNA from relatively small tissue samples. The RNA is clean enough for Rnase protection, cDNA synthesis, and RT-PCR analysis. - [Read RNA Preparation from Cultured Cells or Tissue Samples Protocol]
Arabidopsis can be stably transformed using Agrobacterium tumefaciens-mediated transfer of T-DNA. We describe the generation of transgenic plants via root transformation in tissue culture, which can be useful for transforming sterile mutants. - [Read Root Transformation of Arabidopsis Protocol]

Germ layers are multipotent tissues that have the ability to differentiate into various tissue types. Isolation and manipulation of germ layers is important for examining differentiation. This protocol describes a method for separating postimplantation germ layers. - [Read Separating Postimplantation Germ Layers Protocol]
Protargol-S (silver proteinate) is used with the addition of copper metal. The copper replaces the silver in the connective tissue, allowing a greater differentiation between the nerve fibers and the connective tissue. The silver is reduced with hydroquinone to the visible metallic form. The sections are toned with gold chloride, the gold chloride is reduced with oxalic acid, increasing the deposit of metallic gold on the sections. - [Read Staining of Nerve Fibers Protocol]
Protocol describes a method to stain nerve fibers in tissue slices of avian embryos using an antibody against the 160-kD subunit of neurofilaments. This allows the comparison of the branching pattern of motor and sensory neurons between control and experimental embryos. The tissue is cut in slices using a vibratome or tissue slicer. The protocol is suitable for older embryos after approximately stage 33 and regions that are not accessible by whole-mount analysis. - [Read Staining of Tissue Slices for Analysis of Axonal Pathfinding in dsRNA-Treated Avian Embryos]

This unit on sterility in the tissue culture environment describes methods for sterilization of liquid and dry goods used for tissue culture and filtration of liquids to prevent contamination of cultures. - [Read Sterilization and Filtration Protocol]
GUS is used as a tag to address nuclear localization whereas GFP is more versatile. GFP is detectable directly in living cells, GUS is only detected indirectly by staining of fixed tissue which may lead to artifacts or may obscure problems with protein solubility. In this protocol, protein localization is routinely assayed after particle-mediated transient transformation of onion epidermal cells. With this method it can be determined rapidly whether a given fusion protein is active and.... - [Read Subcellular Localization of GUS- and GFP-Tagged Proteins in Onion Epidermal Cells]
The protocol is one example of differential gene expression analysis of cells obtained from microdissected tissue. Includes: Microdissection and RNA Isolation; Reverse Transcription; PCR; P.A.G.E.; Sequencing of Differentially Expressed Bands. - [Read Targeted Differential Display Protocol]
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]

Tissue subcellular fractionation and protein extraction for use in mass-spectrometry-based proteomics. Although many methods exist for fractionating proteins, the method described here can capture the majority of subcellular fractions simultaneously at reasonable purity. The scalability of this method makes it amenable to small samples, such as embryonic tissues, in addition to larger tissues. The protocol described is for the general fractionation and extraction of proteins from organs / tissue - [Read Tissue subcellular fractionation and protein extraction for use in mass-spectrometry-based proteomic]
Protocol describes the trypsinization of cells in monolayer culture to facilitate subculture or harvesting. To avoid cross-contamination of cells, it is important for each cell line to be subcultured independently. No more than one cell line should be in the tissue culture hood at any one time. - [Read Trypsinization of Cells Grown in Monolayer Protocol]

A single step RNA isolation protocol using Phenol Chloroform Extraction and Acid Guanidinium Thiocyanate. This RNA isolation method uses the fact that guanidinium thiocyanate can simultaneously lyse the cells and inactive cellular RNAses during the initial RNA isolation step allow a single step in the method.
Paraffin Embedding Protocol for molecular profiling. This Paraffin Embedding Protocol describes the processing of the tissues into sections following ethanol fixation. Molecular profiling (MP) is a technique that is used to visualize the global patterns of RNA expression or protein expression in various cell types and disease processes.
