Protocols

• β-galactosidase assay Assay to measure the amount of the enzyme β-galactosidase being produced by a population of cells. Useful as a reporter system.
• Colony PCR PCR with cells as a template. Useful for checking the length of an insert in an introduced plasmid.
• Chemically competent cells generation A technique to produce e.coli cellsreceptive to chemical transformation.
• Electocompetent cells generation A technique to produce e.coli cells receptive to transformation by electroporation
• Electroporation A method for transforming appropriately competent cells with plasmid DNA using electricity.
• Gel Electrophoresis A technique for separating DNA strands of different lengths.
• Gel Extraction of DNA A technique used to isolate a desired fragment of intact DNA from an agarose gel following agarose gel electrophoresis.
• Gibson Assembly A technique for ligating multiple DNA fragments in one step, compatible with standard assembly.
• Glycerol stocks A technique for long term storage of cells at -80 degrees without losing cell vitality.
• LB Agar Plates preparation A method used to prepare agar plate to culture common bacteria.
• MiniPrep - DNA extraction A method used to extract DNA from bacterial cells.
• PCR using a high temperature DNA polymerase A method for amplifying a section of DNA.
• SDS PAGE protein analysis A method used to separate polypeptides of different lengths.
• Restriction Enzyme Digest A method for creating a restriction map of a plasmid.
• Transformation of Bacillus subtilis A technique used to introduce foreign DNA into competent Bacillus cells.
• Transformation of Escherichia coli A method for transforming competent E.coli with DNA
