Protocol describes a method for Caesarean section and fostering. Caesarean section is required if the recipient of an embryo transfer or any pregnant mouse has not given birth by the delivery time normal for the particular strain. - [Read Mouse Caesarean Section and Fostering Protocol]
Method of choice when large amounts of mammalian DNA are required, for example, for Southern blotting (Rapid Isolation of Mammalian DNA, Rapid Isolation of Yeast DNA, Southern Blotting: Capillary Transfer of DNA to Membranes) or for construction of genomic libraries in bacteriophage {lambda} vectors. Approximately 200 µg of mammalian DNA, 100-150 kb in length, is obtained from 5 x 107 cultured aneuploid mammalian cells (e.g., HeLa cells). - [Read Isolation of High-molecular-weight DNA from Mammalian Cells Using Proteinase K and Phenol Protocol]
The transfer of proteins from a Tris/glycine SDS-polyacrylamide gel to a membrane using a semi-dry method is achieved by placing the gel next to a piece of nitrocellulose filter. This sandwich is placed directly between two plate electrodes, and the proteins are then transferred from the gel onto the filter. - [Read Immunoblotting: Semi-Dry Electrophoretic Transfer of Proteins from Gels to Membranes Protocol]
BN-PAGE has become the method of choice for the investigation of the respiratory protein complexes of the electron transfer chains of a range of organisms. It allows the separation in two dimensions of extremely hydrophobic protein sets for analysis and also provides information on their native interactions. In this review we discuss the capabilities of BN-PAGE in proteomics and the wider investigation of protein:protein interactions with a focus on its use and potential in plant science. - [Read Blue-Native PAGE in Plants: A Tool in Analysis of Protein-Protein Interactions]
Protocol for Immunoblot. Includes: Staining and Laser Capture Microdissection; Protein Separation by Polyacrylamide Gel Electrophoresis; Electrophoretic Transfer To a Membrane (Nylon, PVDF or Nitrocellulose); Primary and Secondary Antibody Incubations; Visualization. - [Read Immunoblot Protocol]
This protocol describes the preparation of polyethylenimine (PEI)/DNA nanoparticles for targeted gene delivery. This delivery strategy improves the efficiency of gene transfer by enhancing the entry of gene vectors into the desired cells and reducing uptake by nontarget cells. We describe here methods for the conjugation of targeting peptides to PEIs, formation of DNA complexes using the conjugated PEIs or nonconjugated PEIs together with targeting peptides, and cell transfection. - [Read PEI Nanoparticles for Targeted Gene Delivery Protocol]
Protocol describes oviduct transfer of mouse embryos. It is based on the Whittingham method, which applied a well described procedure for the rat to the mouse. It is best to practice this procedure first on a cadaver and then on an anesthetized 0.5-dpc pseudopregnant mouse using a dye solution or blue Affigel beads rather than embryos to gain experience in finding the opening of the oviduct (infundibulum). - [Read Oviduct Transfer Protocol]
Transfer of proteins from a Tris/glycine SDS-polyacrylamide gel to a membrane using the submerged method is achieved by placing the gel next to a piece of nitrocellulose filter, submerging this sandwich in a large volume of transfer buffer in a transfer tank, and running current from one side of the transfer tank to another. The proteins are then eluted by transferring them from the gel onto the filter. - [Read Immunoblotting: Submerged Electrophoretic Transfer of Proteins from Gels to Membranes Protocol]
Protocol for 96-well confirmation Yeast PCR. Includes: Clonal purification; Generate a master plate (96-well format); Making a frozen backup stock; Confirmation PCR for one Row; ORF Specific Confirmation PCR --> "A-B" primers (upstream junction); Transfer template DNA to multiwell PCR plate; Prepare and dispense master mix for A-B PCR. - [Read 96-Well Confirmation Yeast PCR Protocol]
Tubulin is polymerized into microtubules by incubating tubulin at 37°C with GTP. A nucleation seed is added when the purpose is to assay microtubule elongation. Tubulin can also be polymerized for the purposes of recycling the tubulin or labeling the microtubules with fluorescently labeled tubulin. Based on the protocol by Timothy Mitchison of Harvard University.
This Microarray Protocol Preparation of Fluorescent DNA Probes from Human mRNA protocol describes the production of probes labeled with the fluorescent dyes, Cy3 and Cy5, following the synthesis of cDNA from human mRNA and the hybridization of the probes to DNA microarrays.
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.
In Vitro Translated Xenopus Mos Kinase Assay Protocol. In response to progesterone, immature Xenopus oocytes mature to eggs that can be fertilized. The Mos protein kinase is essential for oocyte maturation, most likely due to its ability to activate the MAP kinase cascade. This MAP kinase cascade eventually leads to the activation of Cdc2/cyclin B and entry into M phase. In this protocol, tagged Mos kinase is translated in vitro, immunopurified, and used in a kinase assay.
A protocol for the selection of Phage Antibodies using Immobilized Antigen. This method describes the selection of antibodies from bacteriophage antibody libraries that recognize a specific antigen. The phage display library of antibody-displaying phage particles is exposed to antigen attached to a solid substrate (Nunc Immuno™ tubes). The phage particles with affinity for antigen bind to the immobilized antigen and are selected from the library of phage expressing antibodies.
