This is the correct protocol if you are using the C3019I cells. Description. Most bacteria do not usually exist in a “transformation ready” state, but the bacteria can be made permeable to the plasmid DNA, and cells that are capable of transformation are referred to as “competent.” Competent cells are extremely fragile and should be handled gently, specifically kept cold and not vortexed. Can be a number of things, form the transformation protocol and Plasmid Preparation protocol to DNA extraction and confirmation. ..

The volume needed for this amount can be estimated by comparing the intensity of the purified backbone to the 3 Kb marker, which will have 125 ng of DNA. 1 DNA as the transforming principle was demonstrated by Avery et al in 1944. 2) Turn on water bath to 42οC. This is a 40,000-fold dilution of the full transformation and will enable you to estimate transformation efficiency to ensure that full library representation is preserved. Follow the High Efficiency Transformation Protocol above with the following changes: 1. JM109 is a K strain that is recA– and endA– to minimize recombination and improve the quality of plasmid DNA.In addition, the cells carry the F´ episome, which allows blue/white screening. Heat shock at exactly 42°C for exactly 30 seconds. Place on ice for 2 minutes. Chill a metal 96-well block on ice. Highest growth rate on agar plates - visible colonies 6.5 hours after transformation See below for an overview of the set-up. *Bacterial transformation: Transformation is the process by which foreign DNA is introduced into a cell. Bacterial transformation: p.1-3 ; Bacterial Glycerol Stocks for Long-term Storage: p.4 Do not vortex. Add 1 pg-100 ng of plasmid DNA (1-5 µl) to cells and mix without vortexing. A rapid and simple protocol for the transformation of plasmid DNA using CaCl2 is reported.

The exact mechanism of how this process works is still largely unknown, but there are hypotheses on the different aspects of the procedure. It was first reported in Streptococcus pneumoniae by Griffith in 1928. If want to cut at XbaI or other DAM- enzyme site, use SCS110 cells which are deficient in Dam and Dcm methylases. For your ligation, you should use 50 to 100 ng of the prepared backbone. A shortened transformation protocol resulting in approximately 10% efficiency compared to the standard protocol may be suitable for applications where a reduced total number of transformants is acceptable. The word is derived from Griffith's discovery of a "transforming principle". Do not think this is enough information to give an answer. NEB 10-beta/Stable Outgrowth Medium delivers the highest transformation efficiency. Do not mix.
