Protocol for the identification of positive GATEWAY expression clones when both the pENTRY and pDEST vectors contain the same marker for bacterial selection. Protocol describes ways in which difficult vector combinations can be used effectively to obtain the appropriate expression clone without having to convert the pENTRY clone or pDEST clone to vectors with compatible antibiotic resistances. - [Read Identification of Positive GATEWAY Expression Clones Protocol]
The most commonly used markers for selection of transgenic Arabidopsis are resistance to the antibiotic kanamycin and to the herbicide glufosinate ammonium. Resistance to kanamycin is conferred by a bacterial gene encoding the enzyme neomycin phosphotransferase (NPT). In this protocol, kanamycin-resistant seedlings are selected on solid medium. - [Read Kanamycin Selection of Transformed Arabidopsis Protocol]
For both biological and economical reasons, it is important to eliminate mycoplasmas from cell cultures being used for basic research, diagnosis, and biotechnological production. The most commonly used method for elimination, inactivation, or suppression of mycoplasmas in cell cultures is treatment with antibiotics. In general, antibiotic therapies do not result in long-lasting, successful elimination. Also, the cytotoxic properties of antibiotics can cause undesirable side effects on cells. - [Read Mycoplasma Elimination Reagent Protocol]
Protocol describes a target selective S. aureus whole cell assay that combines agar-diffusion and protein over expression techniques. This agar based two-plate differential sensitivity assay was used to help confirm the newly discovered antibiotic platensimycin inhibited bacterial growth by specifically targeting the essential FASII enzyme FabF6. - [Read Target Specific Whole Cell Assay for Antibacterial Drug Discovery Protocol]
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.
