Champion™ Competent Cells
pUC19 Control Plasmid (5 μl, 10-4 μg/μl)
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.

Product Info
The Multiplexing Index Primers contain primer mix for multiplexing library samples for Next Generation Sequencing (NGS) on the illumina platform. Multiplexing of NGS library samples will reduce sequencing costs by pooling multiple NGS libraries into a single flow cell lane.
With library multiplexing, unique index sequence is added to individual sample during NGS library preparation. Therefore, each DNA molecule can be identified after pooling of multiple samples based on the index information they have.
Each of our index primers contains a unique index sequence with 6 bases that can be used to identify libraries. Library multiplexing up to 48 samples is possible.
Multiplexing Index Primers (illumina platform): Even distribution of 48 samples using index primers. 48 libraries were made using the BioDynami NGS DNA Library Prep Kit (Cat. # 30009) and the BioDynami Multiplexing Index Primers (Cat. # 30072). Libraries were pooled at equal concentration and sequenced on the illumina HiSeq 2500. The numbers of reads from 48 libraries were analyzed.
List of index sequence for the primers (each of the index primer mix contains universal primer and one of the index primers). Index number and the index sequence are listed.

Isolate all sizes of circulating and exosomal RNA, including microRNA
Versatile plasma/serum input ranges
No phenol extractions
No carrier RNA
Bind and elute all RNA irrespective of size or GC content, without bias
Concentrate circulating RNA and exosomal RNA into a flexible elution volume
High quality, purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing. Find out more information on Norgen’s NGS services
Compatible with Streck Cell-Free RNA BCT® Tubes
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
These kits provide a fast, reliable and convenient method to purify and concentrate high quality, high purity and inhibitor-free cell-free circulating and exosomal RNA using a convenient spin column method. These kits can purify RNA from fresh or frozen serum or plasma samples prepared from blood collected on either EDTA or Citrate. Plasma samples prepared from blood collected on heparin should not be used, as heparin can significantly interfere with many downstream applications such as RT-PCR. The purified plasma/serum RNA is fully compatible with all downstream applications including PCR, qPCR, methylation-sensitive reverse transcription qPCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, expression array assays, and NGS.
Background
Plasma/Serum cell-free circulating RNA or exosomal RNA has the potential to provide biomarkers for certain cancers and disease states. Exosomes are 40 – 150 nm membrane vesicles, which are secreted by most cell types. Exosomes can be found in saliva, blood, urine, amniotic fluid and malignant ascitic fluids, among other biological fluids. Evidence has been accumulating recently that these vesicles act as cellular messengers, conveying information to distant cells and tissues within the body. These exosomes may play a functional role in mediating adaptive immune responses to infectious agents and tumours, tissue repair, neural communication and transfer of pathogenic proteins. For this reason exosomal RNAs may serve as biomarkers for various diseases including cancer. As the RNA molecules encapsulated within exosomes are protected from degradation by RNAses they can be efficiently recovered from biological fluids, such as plasma or serum.
Plasma/Serum RNA Purification Mini Kit
This kit can purify RNA from fresh or frozen serum or plasma samples prepared from blood collected on either EDTA or Citrate, from volumes ranging from 50 µL to 200 µL. The purified plasma/serum RNA is eluted in a flexible final volume of 10 µL to 25 µL.
Plasma/Serum RNA Purification Midi Kit
This utilizes a two column method, and can purify RNA from fresh or frozen serum or plasma samples prepared from blood collected on either EDTA or Citrate, from volumes ranging from 250 µL to 1.5 mL. The first column will handle the large volume input of bodily fluids that is followed by a concentration on a mini column for a final elution of 50 µL to 100 µL.
Plasma/Serum RNA Purification Maxi Kit
This kit can purify RNA from fresh or frozen serum or plasma samples prepared from blood collected on either EDTA or Citrate, from volumes ranging from 2 mL to 5 mL. The first column will handle the large volume input of bodily fluids that is followed by a concentration on a mini column for a final elution of 50 µL to 100 µL.
*This kit is suitable for the isolation of RNA from fresh or frozen serum or plasma prepared from blood collected on either EDTA or Citrate. Plasma samples prepared from blood collected on heparin should not be used as heparin can significantly interfere with many downstream applications such as RT-PCR.

Storage Conditions and Product Stability
All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment. It is recommended to warm Lysis Buffer A for 20 minutes at 60°C if any salt precipitation is observed.
Thymidylate Synthase (TS) is a crucial enzyme responsible for the synthesis of 2′-deoxythymidine-5′-monophosphate (dTMP) a precursor for thymidylate which is necessary for DNA replication and repair from 2′-deoxyuridine-5′-monophosphate (dUMP). In terms of cancer, TS is an important target for cancer treatment as the inhibition of TS and therefore nucleotide synthesis necessary for cell growth has shown to be a vital part for successful treatment against colorectal, pancreatic and breast cancers.
