N-(Propargyl-PEG2)-PEG3-N-Boc

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.

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.

Magnetic Beads (tRNA Purification)

Solid Phase Reversible Immobilization magnetic beads has been used for nucleic acids purification because they are effective, simple, and fast. The carboxyl groups coated beads are paramagnetic particles that reversibly bind to nucleic acid. However, there is a drawback for magnetic beads that it can only purify DNA/RNA that are 100 base pairs or longer. tRNA and other DNA/RNA fragments shorter than 100 base pairs are not effectively recovered. We have developed Magnetic Beads (tRNA Purification) to overcome the hurdle.

The Magnetic Beads (tRNA Purification) solves the tRNA and short DNA/RNA purification problem. The beads with our proprietary technology purify tRNA effectively by removing impurities and unwanted components such as dNTPs, detergents, salts, proteins, and other contaminants. The magnetic bead reagents can be used for oligo (>70 nt) applications.

Workflow without large RNA/DNA contamination

In the case of samples contaminated with RNA/DNA such as rRNA and DNA, our magnetic beads can effectively remove RNA/DNA that are 180 nt and larger. Purified tRNA are ideal for applications requiring high quality, as the fragments are free of impurities and contaminants.

Workflow with large RNA/DNA contamination

Comparison of tRNA and 70 nt oligos recovery. BioDynami beads (tRNA purification) successfully recovered DNA fragments both yeast tRNA and 70 nt oligos.

Recovery of tRNA and 70 nt oligos with BioDynami magnetic Beads (tRNA Purification). Yeast tRNA and 70 nt oligos were used as input. Input and recovered oligos were quantified with ssDNA Quantification kit (BioDynami Cat. # 40043) and RNA Quantification kit (BioDynami Cat. # 40044).
