Alkaline agarose gels are used chiefly to measure the size of first and second strands of cDNA (Construction of cDNA Libraries Stage 1: Synthesis of First-strand cDNA Catalyzed by Reverse Transcriptase) and to analyze the size of the DNA strand after digestion of DNA-RNA hybrids with nucleases such as S1. - [Read Alkaline Agarose Gel Electrophoresis Protocol]
This stage achieves four goals: polishing the ends of double-stranded DNA, ligation of synthetic linkers or adaptors, digestion of the attached linkers to create cohesive termini, and preparing the cDNA for cloning. - [Read Attachment of Linkers or Adaptors for Construction of cDNA Libraries]
Protocol describes how to construct a library of 35-45-kb fragments of genomic DNA in the double cos site cosmid vector, SuperCos-1. The steps include: Linearization and dephosphorylation of SuperCos-1 DNA; Partial digestion of high-molecular-weight DNA with MboI; Dephosphorylation of high-molecular-weight genomic DNA; Ligation of cosmid arms to genomic DNA: Packaging and plating recombinants; Isolation and analysis of recombinant cosmids: Validation of the library. - [Read Construction of Genomic DNA Libraries in Cosmid Vectors Protocol]

CHO Lec3.2.8.1 cells have 4 independent mutations in the N and O glycosylation pathways. When cultured with alpha-glucosidase I inhibitor N-butyl-deoxynojirimycin, glycoproteins produced in CHO Lec3.2.8.1 cells are completely susceptible to Endo H digestion. Endo H cleaves chitobiose, leaving a single N-linked N-acetylglucosamine per site which is ideal for maintenance of protein solubility and special carb-protein interactions, such as between the first N-acetyl glucosamine residue and tryp. - [Read Establishment of Stable Transfectant of CHO Lec Cells Protocol]

In this method, the nuclease BAL 31 is used to make uni- or bidirectional deletions in a segment of cloned DNA. BAL 31 is a complex enzyme and tends to digest a population of double-stranded DNA targets in an asynchronous fashion, Deletions created by BAL 31 are therefore far more heterogeneous in size than those created by processive enzymes such as exonuclease III. - [Read Generation of Bidirectional Sets of Deletion Mutants by Digestion with BAL 31 Nuclease Protocol]

Inverse PCR is used to amplify and clone unknown DNA that flanks one end of a known DNA sequence and for which no primers are available. The technique involves digestion by a restriction enzyme of a preparation of DNA containing the known sequence and its flanking region. The individual restriction fragments (many thousands in the case of total mammalian genomic DNA) are converted into circles by intramolecular ligation, and the circularized DNA is then used as a template in the PCR. - [Read Inverse PCR Protocol II]
This procedure describes the isolation and culture of adult mouse cardiac myocytes from two or more hearts. Includes
modifications for the digestion of two or more hearts in the same procedure and subsequent pooling of myocytes derived from the multiple hearts. The isolation procedure is performed by one or more technicians and routinely yields approximately 1
million rod-shaped myocytes per heart. - [Read Isolation of Adult Mouse Cardiac Myocytes from Two or More Hearts Protocol]

Presents two methods for preparing dendritic cells (DCs), a highly specialized type of antigen-presenting cell (APC). The first method involves the isolation of DCs from mouse spleen, resulting in a cell population that is highly enriched in accessory cell and APC function. A support protocol for collagenase digestion of splenocyte suspensions is described to increase the yield of dendritic cells. The second method involves generating large numbers of DCs from mouse bone marrow progenitor cells. - [Read Isolation of Dendritic Cells Protocol]
DNA microarrays are an ordered arrangement of DNA molecules complementary to genes of interest that are "spotted" by robotic equipment onto a glass slide substrate. The expression of genes in cells can be monitored with microarrays by preparing cDNA from the mRNA of cells of interest and measuring the hybridization to the microarray. This protocol describes the labeling of genomic DNA for use as a probe for hybridization to the cDNA spotted on the array.
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.
This protocol describes the electroporation of the BMH 81-17 mut S strain that is recommended for tranformation of the site directed mutagenesis of dsDNA (See Protocol on Site-Directed Mutagenesis on Double Stranded DNA). BMH 81-17 mut S are a mismatch repair defective (mut S) Escherichia coli strain. The probability that the two mutations will cosegregate during the first round of DNA replication is increased in this strain.
