Topo Cloning procedure for cloning of small amounts DNA fragments by PCR. Cloning the PCR fragment into the TOPO vector, transforming E. Coli cells, and using blue/white selection to determine transformants. Culture inoculation, Qiagen Plasmid Prep protocol for plasmid isolation of the plasmid containing the cloned copies. Preuss Lab, Univ. Chicago. - [Read Topo Cloning Procedure]
Protocol details the preparation of fluorescently labeled target samples and hybridization of these samples to a microarray of Agilent inkjet-deposited cDNAs. The procedure requires a minimum of 5 mg of purified total RNA as starting material. Includes: First Strand cDNA Synthesis; Second Strand cDNA Synthesis; cDNA Cleanup and Precipitation; In vitro Transcription; Cleanup and Quantification of in vitro Transcribed RNA; Fluorescent Labeling of the Target Samples. - [Read Transcript Profiling by Microarray Analysis Protocol.]

The following procedure is for simultaneous transfection and plating of RAW 264.7 cells. This protocol results in approximately 50% to 70% cell viability, and of those viable cells, 20% to 40% are transfected when using pEYFP-N1
from Clontech. Include: Procedure for Splitting Cells before Transfection; Procedure for Preparing Lipofectamine 2000 and DNA; Preparation of RAW 264.7 Cells for Transfection. - [Read Transfecting and Plating RAW 264.7 Cells with Lipofectamine 2000 Protocol]
Protocol for the transformation of Aspergillus niger. This procedure is done by first digesting the outer cell wall, forming protoplasts, and then by making holes in the membrane
through which the dna can enter using calcium chloride and polyethylene glycol. Includes: Protocol for making A.niger protoplasts; Transformation; Plating. - [Read Transformation of Aspergillus niger Protocol]
This procedure, which uses a root transformation protocol, provides a rapid method for assessing gene expression in Arabidopsis roots. It is useful for testing promoter:reporter gene constructs, for expressing genes, the overexpression of which is lethal in whole plants, and for transforming the roots of plants that are recalcitrant to conventional transformation techniques. The protocol has been used successfully with Ws, No-0, and RLD ecotypes. - [Read Transgene Expression in Regenerated Roots]
This transient transfection protocol for the ecotropic/amphotropic producer line includes instructions for titering and concentration of viral stocks. This procedure gives consistently higher transfection efficiency. - [Read Transient Transfection: Viral Production]
Fixation can mask epitopes. However, it is often possible to re-expose them using a gentle incubation with proteases, which removes obstructing structures and allows antibody access, as described here. Many proteases can be used for this procedure, including very crude preparations of proteases, such as pronase. However, using a better-characterized protease, such as trypsin, allows a more controlled reaction and better comparison between experiments. - [Read Unmasking Hidden Epitopes with Proteases Protocol]
Protocol describes a procedure for uterine transfer, which is used for chimera production. The method is based on extensive work which resulted in the first successful development and birth of in-vitro-cultured mouse embryos. It is best to practice this procedure first on a cadaver and then on an anesthetized 2.5-days post coitum (dpc) pseudopregnant mouse using blue Affigel beads rather than embryos. - [Read Uterine Transfer Protocol]

Procedure describes how it denatures most of the modification and degradation proteins immediately giving the most accurate read out of the true levels of protein at the time of harvest. However, in cases where detection is a problem, a limited purification (e.g. isolation of nuclear extract for the detection of transcription factors) might be required to allow analysis. - [Read Western Blot Analysis of Endogenous Gene Expression Protocol]
Protocol describes the general procedure for creating mutations in the DNA of Drosophila by exposure to X-rays. Irradiation of cells with X-rays creates double strand breaks (DSBs) in DNA. Mutations introduced in the DNA of germ line cells (sperm) are propagated by mating the exposed males to virgin females. The progeny of this cross can be mated to each other so that a percentage of the subsequent offspring will have two copies of the same mutant allele. - [Read X-Ray Mutagenesis of Drosophila 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.
