Magnetic Beads (microRNA & Oligo Purification)

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).

Overview

• Detection kits for Streptococcus agalactiae
• Available in TaqMan format for analysis

Mastitis is the single most costly disease of dairy cattle resulting in the reduction of milk yield and quality. The inflammation of the udder is mainly caused by infection of various bacteria. One of such mastitis bacteria, Streptococcus agalactiae, is highly infectious and causes mainly subclinical infections, which are not identified by the herdsman. As a result, S. agalactiae can spread widely within a herd, causing immediate loss due to reduced milk. S. agalactiae is a gram-positive bacteria belonging to the Group B streptococci. Traditional cultural identification of S. agalactiae is based on S. agalactiae being beta-hemolytic as well as presence of group B Lancefield antigen and by its ability to hydrolyze sodium hippurate.

Description

Description

Cell membrane preparations containing nicotinic AChRs that are ligand-gated ion channels that form pores in cells plasma membranes, mediating fast signal transmission at synapses. Nicotinic AChRs are involved in a wide range of physiological processes, and can be either neuronal or muscle-type.  The membrane preparations we have developed are suitable for receptor binding assays in which muscle type nicotinic AChRs are needed.  The membranes are tested in several functional binding assays and quality testing criteria to meet binding specifications.
