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.

Introduction

The Kit provides fast purification of high-quality RNA from plants, cell, tissues, and yeast using silica-membrane spin columns with a binding capacity of 100μg RNA. There is no need for phenol/chloroform extractions and time-consuming steps such as CsCl gradient ultracentrifugation or precipitation with isopropanol or LiCl. RNA purified using the RaPure Total RNA Purification System can be used for applications such as RT-PCR, Northern blotting, poly A+ RNA (mRNA) purification, nuclease protection, and in vitro translation.

Principle

The Kit isolates total RNA from up to 150mg plant tissue. A short workflow enables RNA isolation with genomic DNA removal in less than 25 min. Samples are first lysed and homogenized. The lysate is passed through a DNA Mini column, ethanolis added to the flow-through, and the sample is applied to an RNA column. RNA binds to the membrane and contaminants are washed away. High-quality RNA is eluted in as little as 30µl water using the Kit.

Advantages

• Efficient removal of DNA – unique genomic DNA removal column without DNase treatment
• High quality – high purity total RNA can be directly used in various sensitive downstream applications
• Fast – several samples can be extracted in 25 minutes by column method
• Safe – no phenol chloroform extraction required
• Sensitive – RNA can be recovered at the level of PG
• Broad spectrum – various types of plant samples can be processed by diversity of operating procedures

Storage and Stability

The Kit can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. Make sure that all buffers are at room temperature when used. During shipment, crystals or precipitation may form inthe Buffer RLC/PRC1. Dissolve by warming buffer to 37°C.

Purchase Guide

1. When dealing with woody or uncommon samples, R4150 is recommended first. R4150 contains two polysaccharide/polyphenol lysis buffer, which is the most universal product.

2. R4151 is recommended for handling common economic crop samples for the first time. Strong lysis solution can be used to process easy-extraction samples. The amount of corn or rice leaves samples can reach up to 300mg.

3. R4165 adopts CTAB/chloroform method, which can also handle a large number of difficult-to-extraction plants, but requires contact with chloroform substitutes, which is less safe than other kits. This kit uses DNase Ⅰ to remove DNA, which is also a good choice for extracting polysaccharide/polyphenol-rich plant samples.

4. R4014 is recommended for fruit/starch plant samples, which uses improved trizol pre-treatment, single column operation and is more economical.
