Category: Fungi Protocols: Aspergillus Protocols

The technique makes use of an Escherichia coli strain expressing the redΑßΓ operon under the control of an inducible promoter. This enables the strain to carry out homologous recombination with only 50-60 bp of homologous sequence. The procedure does not require any DNA ligation and is very rapid. It allows a single gene or region on a cosmid to be replaced by a bi-functional selectable marker (having both an E. coli and an A. fumigatus marker). - [Read A Rapid Method for Generating Gene Deletions in Aspergillus fumigatus Protocol]

ANTIBODY PURIFICATION by affinity chromatography. By Beth, Mullins Lab UCSF. To affinity purify antibodies, generate lots of E. coli lysate that contains your antigen. If the protein can stand freeze thawing, then go ahead and purify the protein from e. coli lysate and keep it frozen until you need to couple it to a CH-sepharose column. - [Read ANTIBODY PURIFICATION by affinity chromatography]

4 strains of E. coli are used in these studies: JM101 for M13 infection and isolation, XL1BMRF'for M13 or pUC-based DNA transformation, and ED8767 for cosmid DNA transformation. To maintain their respective F' episomes necessary for M13 viral infection, JM101 is streaked onto a M9 minimal media plate and XL1BMRF' is streaked onto an LB plate containing tetracycline. ED8767 is streaked onto an LB plate. These plates are incubated at 37degC overnight. For each strain, 3 ml. of appropriate liquid.. - [Read Bacterial Cell Maintenance Protocol]

Category: PCR Protocols: PCR Cloning Protocols

Protocol is for bidirectional, blunt-end cloning of DNA fragments.  The target DNA is PCR amplified and 3'-extensions are polished with Pfu DNA polymerase.  The amplicon is ligated to a blunt-ended plasmid DNA, and the products of the ligation reaction are used to transform competent Escherichia coli.  A restriction enzyme is added to the ligation reaction to relinearize any self-religating vector DNA. - [Read Bidirectional Cloning of PCR Products Protocol]

Category: PCR Protocols: PCR Cloning Protocols

Pairs of oligonucleotide primers used in PCR are often designed with restriction sites in their 5' regions.  In many cases, the sites are different in the two primers.  In this case, amplification generates a target fragment whose termini now carry new restriction sites that can be used for directional cloning into plasmid vectors.  The purified fragment and the vector are digested with the appropriate restriction enzymes, ligated together, and transformed into E. coli. - [Read Cloning PCR Products by Addition of Restriction Sites to the Termini of Amplified DNA Protocol]

Category: DNA Protocols: cDNA Library Protocols

Here, the DNA-RNA hybrids synthesized in Stage 1 are converted into full-length double-stranded cDNAs. The primers for synthesis of second-strand cDNA are created by RNase H, which introduces nicks into the RNA moiety of the cDNA-mRNA hybrids. E. coli DNA polymerase I extends the newly created 3'-hydroxyl termini, using the first-strand cDNA as a template. - [Read Construction of cDNA Libraries Protocol]
