N-Boc-N-bis(PEG4-Propargyl) is a bifunctional PEG compound containing two terminal alkynes that are combined together at a Boc-protected secondary amine. Terminal alkynes are most commonly used in copper click chemistry with azides to form stable triazoles with the target molecule. The secondary amine may be deprotected under acidic conditions to allow for alkylation at that position, increasing the molecule’s structural complexity. The use of a central amine also allows for hydrogen bonding, further increasing this compound’s water solubility.

Norgen’s Urine microRNA Purification Kit provides a rapid method for the isolation and purification of small RNA molecules (All sizes, including < 200 nt) from urine samples. These small RNAs include regulatory RNA molecules such as microRNA (miRNA) as well as tRNA and 5S rRNA. Small RNA molecules are often studied due to their ability to regulate gene expression. Typically miRNAs are 20-25 nucleotides long and regulate gene expression by binding to mRNA molecules and affecting their stability or translation. Several recent studies have shown that miRNA regulates cell growth and apoptosis. Furthermore, clinical and experimental analyses suggested that miRNAs may function as a novel class of oncogenes or tumor suppressor genes. MicroRNA expression profiles of different tumor types, relative to their normal tissues, have recently been shown to provide phenotypic signatures for particular cancer types. Unique patterns of aberrant miRNA expression may serve as molecular biomarkers for tumor diagnosis, prognosis of disease-specific outcomes, and prediction of therapeutic responses.
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.
Solid Phase Reversible Immobilization magnetic beads consist of paramagnetic particles coated with carboxyl groups that reversibly bind DNA. They are used for DNA purification because they are fast, simple and efficient. We have developed our own beads technology that are different from other SPRI beads technologies.
Our Magnetic Beads(DNA & RNA Purification) combines BioDynami’s proprietary chemistries with reversible DNA-binding properties of magnetic beads. The magnetic beads, which are unique from other SPRI beads, are developed for effective nucleic acid purification by removing unwanted components such as salts, dNTPs, enzymes, primers, adapters, and other impurities. The beads are RNase free, can be used for applications of DNA, and even work with more sensitive RNA without any additional cost.
Our magnetic beads are optimized to selectively bind DNA fragments of 100 bp and larger, and RNA fragments of 200 bases and larger, similar to other SPRI beads such as AMPure® XP* and SPRIselect*. Purified DNA and RNA are suitable for downstream applications requiring high quality DNA and RNA, as the purified fragments are free of contaminants and impurities. The beads can be used for NGS library purification, PCR fragment cleanup, molecular cloning, or even nucleic acid concentration.
The beads can also be used for size selection of DNA fragments ranging from 150 bp to 800 bp by changing the bead-to-sample volume ratio and performing single or double-size selection. The beads are an ideal choice for NGS library preparation. They can be easily integrated into the standard workflow of NGS library preparation since the volume ratio is similar for protocols using standard magnetic beads.
Features:
Effective recovery of DNA and RNA samples
DNA fragments greater than 100 base pairs
RNA fragments greater than 200 bases
Removal of unwanted components and impurities
Fragment size selection for specific applications
Consistent single or double-size selection
Flexibility: compatible with manual and automated processing
Cost effective alternative to other beads such as AMPure® XP* and SPRIselect* with equivalent performance
* AMPure® XP and SPRIselect are trade marks of Beckman Coulter.
Magnetic beads recovery rate. dsDNA and ssDNA of genomic DNA, 1 kb DNA, and 200 bp DNA fragments were used. Total RNA was also tested.
Comparison of elution volume vs yield. 40 ul , 30 ul, and 20 ul of elution volume were used. BioDynami magnetic beads have better recovery rates at low elution volume when compared to other SPRI beads such as AMPure® XP*.
