Description 

Champion™ E. coli Transformation Kit provides an easy method for rapid preparation of chemically competent cells with high transformation efficiency from fresh culture, overnight culture, or even directly from bacterial colonies on the plate. The competent cell preparation method eliminates the requirement of time-wasting wash step. In addition, preparation of competent cells from overnight culture or directly from bacterial colonies provides flexibility to cloning experiment. The resultant competent cells can be immediately used or stored at -70°C for one year. This kit includes a specialized SMO-Broth™ medium and a unique Champion™ CC Buffer for culturing and preparing competent cells efficiently. Following the simple and quick competent cell preparation protocol from fresh culture, the transformation efficiency is typically ranged from 10⁸–10⁹ cfu/μg transformants/μg of pUC19 plasmid DNA, but varies depending on the E. coli strains. The resultant competent cells can be further transformed using time-saving transformation protocol, eliminating the requirement of heat-shock and recovery steps. 

Features

• Flexible– fresh culture, overnight culture, 4°C stored liquid culture or even colonies on agar plate can be used for transformation. 
• Fast and Easy– only few steps for preparation; suitable for time-saving transformation 
• High efficiency– up to 109 cfu/μg 
• Personalization– suitable for most E. coli strains

Specifications

Features	Specifications
Main Functions	Extract total pathogen nucleic acid from cell-free/low-content cell biological samples such as body fluids, serums, plasma, tissue homogenate supernatant.
Applications	RT-PCR，PCR
Products	Pathogen DNA / RNA
Purification method	Polydisperse magnetic beads
Purification technology	Magnetic beads technology
Process method	Manual or automatic
Sample type	cell-free/low-content cell biological samples such as body fluids, serums, plasma, tissue homogenate supernatant
Sample amount	200-300μl
Adaptive instrument	Nucleic acid extractor, pipetting workstation

Principle

This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and Protease. After adding magnetic particles and binding solution, DNA/RNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were washed with washing solution to remove proteins and impurities, washed with ethanol to remove salts, and finally DNA/RNA was eluted by Buffer NFW.

Advantages

• Fast – several samples can be extracted in 40 minutes by column method
• High quality – high purity total RNA / DNA can be directly used in various sensitive downstream applications
• Safe – no phenol chloroform extraction required
• Sensitive – DNA/RNA can be recovered at the level of PG

Storage and Stability

MagPure Particles and Proteinase K should be stored at 2–8°C upon arrival. However, short-term storage (up to 8 weeks) at room temperature (15–25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15–25°C) and are stable for 18 months under these conditions.
