Introduction

This Kit is designed forpurification of high quality circulating DNA (cfDNA) from 1-6ml cell-free bodyfluids (such as plasma, serum). The purified DNA is suitable for direct use indownstream applications such as PCR, real-time PCR, Biochip analysis and NGS.

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. DNA is released into the lysate. After adding magnetic particles and binding solution, DNA 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 was eluted by elution buffer.

Advantages

• Economy – less than 50% of the price of Qiagen and other imported products
• Automatic – without labour
• High purity – OD 260 / 280 : 1.7-1.9, OD 260 / 230 :1.5-2.0

Storage and Stability

Proteinase K, Carrier RNA and MagPure Particles F should be stored at 2–8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15–25°C) does not affect their performance.Theremaining kit components can be stored dry at room temperature (15–25°C) and are stable for at least 18 months under these conditions.The entire kit can be stored at 2–8°C, but in this case buffers should beredissolved before use. Make sure that all buffers are at room temperature when used.

General information

Champion™ Competent Cells are chemically competent cells, which were prepared by SMOBIO to make E. coli perform excellent transformation efficiency. Standard transformation protocol is recommended for large plasmids or non-ampicillin selection. Time-saving transformation protocol is recommended for simple and rapid transformation. Champion™ Competent Cells are one of the fastest and simplest ready-to-use competent cell products in the world.

Kit contents

1. Champion™ Competent Cells
2. pUC19 Control Plasmid (5 μl, 10-4 μg/μl)
3. Champion™ Transformation Protocol Card

Shipping condition

Throughout the shipping process, the temperature is maintained under -70°C. 

Storage and expiration 

Champion™ Competent Cells must be stored between -70°C to -80°C. Subsequent freeze-thaw cycles will reduce transformation efficiency. If high efficiency is required for the experiment, do not use aliquots that have gone through several freeze-thaw cycles. The efficiency of Champion™ Competent Cells lasts for 1 year with proper storage.
