Propargyl-PEG8-t-butyl ester is a PEG reagent with an alkyne group and a t-butyl group. The alkyne group enables the formation of triazole linkage with azide-bearing compounds or biomolecules; copper is required as a catalyst. The t-butyl group can be hydrolyzed under acidic conditions. The hydrophicility of the molecule is improved by having 8 units of PEG. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

The Fructan Assay Kit is suitable for the specific measurement of fructan in plant extracts, animal feed and food products containing starch, sucrose and other sugars. It is used in three validated methods for the determination of fructan: AOAC method 999.03 (foods), AOAC method 2018.07 (Animal Feed) and AOAC method 2016.14 (infant formula and adult nutritionals).
New, improved procedure.
In the most recent development, a recombinant endo-levanase has been incorporated into the fructanase mixture, extending the use of the method to the measurement of levan-type fructans as are present in grasses such as timothy, cocksfoot, ryegrass and red fescue.
The method described in this booklet employs ultra-pure, recombinant enzymes and specifically measures fructans including inulin-type fructans from chicory, dahlia, jerusalem artichoke; highly branched fructans from onion and wheat stems and leaves; and levan-type fructans from pasture grasses such as timothy grass. The enzymes employed are completely devoid of contaminating enzymes active on β-glucan or gluco-oligosaccharides.
All kit reagents stable for > 2 years after preparation

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).

TCO-PEG12-DBCO is a long chain PEGreagent containing a TCO and a DBCO moiety. TCO group specifically and efficiently reacts with terrahydrazine under mild condition. DBCO is very reactive toward Azide through click chemistry, the PEG spacer increases the aqueous solubility of the reagent. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
