Propargyl-PEG5-NHS ester has a propargyl group and an NHS ester group. The terminal NHS ester and is an amine reactive moeity which is useful for derivatizing peptides, antibodies, amine coated surfaces etc. The propargyl group can participate in Click Chemistry reactions with azide compounds, copper is needed for catalyzation. The PEG units can enhance the hydrophilicity of the molecule. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Solid Phase Reversible Immobilization magnetic beads are often used for DNA purification because they are simple, fast, and effective. The beads are paramagnetic particles coated with carboxyl groups that reversibly bind to nucleic acid. However, Standard SPRI beads can only purify DNA/RNA fragments that are 100 base pairs or longer. DNA/RNA fragments shorter than 100 base pairs are not effectively recovered by SPRI beads. We have developed Magnetic Beads (microRNA & Oligo Purification) to solve the problem.
With our proprietary beads technology, the beads overcomes the hurdle of the short DNA/RNA recovery problem. The magnetic beads is ideal for microRNA purification, oligo purification, short DNA/RNA purification, and removing impurities and unwanted components such as dNTPs, detergents, salts, proteins, and other contaminants effectively. The magnetic bead reagents are RNase-free and can be used for both DNA and RNA applications.
Our magnetic beads are optimized for microRNA purification, oligo purification, and DNA/RNA purification. The fragments can be as short as 20 bases, such as microRNA, tRNA, dsDNA fragments 20 bp or longer, ssDNA fragments 20 nt or longer, RNA fragments 20 nt or longer, DNA/RNA hybrid fragments 20 bp or longer, and oligos and chimeric oligos 20 nt or longer. Purified short DNA and RNA fragments are ideal for applications requiring high-quality fragments, as the fragments are free of impurities and contaminants.
Comparison of short DNA fragments recovery. BioDynami 20 bp DNA ladder (Cat. # 10002) was used as DNA input. Ampure XP beads, BioDynami beads (DNA & RNA purification) and BioDynami beads (microRNA & Oligo purification) were tested. Only BioDynami beads (microRNA & Oligo purification) successfully recovered DNA fragments between 20-100 bp.
Recovery of DNA and RNA oligos with BioDynami magnetic Beads (microRNA & Oligo Purification). 20 nt of DNA oligos and RNA oligos were used as input. Input and recovered oligos were quantified with BioDynami ssDNA Quantification kit (Cat. # 40043) and BioDynami RNA Quantification kit (Cat. # 40044).
