Molecular Station is THE largest network of researchers, scientists and science lovers anywhere!
Science, at bottom, is really anti-intellectual. It always distrusts pure reason, and demands the production of objective fact. ~H.L. Mencken, Minority Report: H.L. Mencken's Notebook, 1956
Protocols and information related to preparation and transformation of bacterial cells.
| Preparation and High-efficiency Transformation of Competent E. coli - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot3942 Protocol generates competent cultures of E. coli that can be transformed at high frequencies (5 x 108 transformed colonies/µg of superhelical plasmid DNA). - [Read Preparation and High-efficiency Transformation of Competent E. coli] |
| Preparation and Transformation of Competent E. coli Using Calcium Chloride Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot3932 Protocol used to prepare batches of competent bacteria that yield 5 x 106 to 2 x 107 transformed colonies/µg of supercoiled plasmid DNA. - [Read Preparation and Transformation of Competent E. coli Using Calcium Chloride Protocol] |
| Preparation and Transformation of Competent E. Coli: "Ultra-Competent" Cells Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot3944 Protocol reproducibly generates competent cultures of E. coli that yield 1 x 108 to 3 x 108 transformed colonies/µg of plasmid DNA. The protocol works optimally when the bacterial culture is grown at 18°C. If a suitable incubator is not available, a standard bacterial shaker can be set up in a 4°C cold room and regulated to 18°C. - [Read Preparation and Transformation of Competent E. Coli: "Ultra-Competent" Cells Protocol] |
| Transformation of Agrobacterium Using Electroporation Protocol - http://www.cshprotocols.org/cgi/content/abstract/2006/30/pdb.prot4665 Protocol describes a method for transforming Agrobacterium with plasmid DNA using electroporation in a manner similar to that commonly used for Escherichia coli. Although the transformation efficiency for Agrobacterium is lower than that for E. coli, it is possible to obtain adequate numbers of Agrobacterium transformants with this technique. - [Read Transformation of Agrobacterium Using Electroporation Protocol] |
| Transformation of Agrobacterium Using the Freeze-Thaw Method Protocol - http://www.cshprotocols.org/cgi/content/abstract/2006/30/pdb.prot4666 Protocol describes a method for transforming Agrobacterium with plasmid DNA using a freeze-thaw technique. Although the transformation efficiency for Agrobacterium is lower than that for Escherichia coli, it is possible to obtain adequate numbers of transformants with this technique. - [Read Transformation of Agrobacterium Using the Freeze-Thaw Method Protocol] |
