Describes an experimental cross in mice that can be used to define and map induced germ-line mutations that map to a single chromosome. The cross is a modification and extension of a conventional three-generation recessive mutagenesis screen. Includes: The Mutagenesis Breeding Plan; Consomic Strains; Generating Mutations; Generating and Genotyping G2 Females; Genotyping G3 Progeny; Phenotyping G4 Progeny; etc.. - [Read A Targeted Screen to Detect Recessive Mutations that have Quantitative Effects Protocol]

Category: Gene Delivery Protocols: DNA Nanoparticles Protocols

This protocol describes a stepwise procedure to prepare nucleic acids encapsulated in a polyethylene glycol (PEG)-shielded nanolipoparticle (NLP) that contain a bioresponsive lipid and ligand. This process provides several advantages for systemic gene delivery. The in vivo circulation time is extended. Also, low pH-sensitive lipids enhance DNA unpacking and endosomal escape. Finally, ligands inserted into the NLP surface can target gene delivery to specific tissues or cells in vivo. - [Read Bioresponsive Targeted Charge Neutral Lipid Vesicles for Systemic Gene Delivery Protocol]

Category: Antibody Protocols: Antibody Production Protocols

Novel strategy of immunizing a phosphorylated peptide or a synthetic phosphopeptide, which corresponds to the protein phosphorylated at a targeted residue. Method has been applied to the production of antibodies that can specifically recognize the other types of site-specific protein modification, such as acetylation, methylation, and proteolysis. - [Read Functional Analyses for Site-Specific Phosphorylation of a Target Protein in Cells]

Category: Genetics and Genomics: Genotyping Protocols: PCR Genotyping

This protocol describes a rapid PCR-based method for identifying targeted ES cell colonies prior to picking. It is based on DNA analysis of a small part of colonies pooled directly from selection plates. Only positive colonies are expanded. - [Read Genotyping Embryonic Stem (ES) Cell Colonies Prior to Picking Protocol]

Category: Gene Delivery Protocols: DNA Nanoparticles Protocols

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]

Category: PCR Protocols: PCR Cloning Protocols

In this protocol sequences cloned in standard bacteriophage or plasmid vectors are amplified in PCRs containing primers targeted to flanking vector sequences.  The amplified fragments can be analyzed by gel electrophoresis, DNA sequencing, and/or restriction mapping.  Many colonies or plaques can be assayed simultaneously. - [Read Rapid Characterization of DNAs Cloned in Prokaryotic Vectors Protocol]
