3,4-Dibromo-Mal-PEG4-amide-DBCO is a PEG linker containing a dibromomaleimide group and a terminal DBCO group. The dibromomaleimide group allows for two points of attachement because both of the bromine atoms can be substituted. The DBCO groups is commonly used for copper-free Click Chemistry reactions due to its strain promoted high energy. PEG linkers are hydrophilic moieties, therefore the attachment of a PEG linker to a compound increases it’s water solubility properties in aqueous media. Reagent grade, for research purpose.

Q-PAGE™ Bis-Tris Precast Gel is a high-performance and easy to use precast polyacrylamide gel for electrophoresis in Bis-Tris buffer system (MOPS or MES). The optimized gel formula allows Q-PAGE™ Bis-Tris Precast Gel to show improved resolution, accurate results, and an extended shelf-life over conventional Laemmli Tris-HCl gels.
Q-PAGE™ Bis-Tris Precast Gels are available in gradient (4 to 12%) and fixed (8% and 12%) concentrations of polyacrylamide in 12-and 15-well formats. Two available cassette sizes, Mini (10 x 8.3 cm) and Midi (10 x 10 cm), are compatible with most popular protein electrophoresis systems. Q-PAGE™ Mini (QP2XXX) Gels are suitable for Bio-Rad® and other systems. Q-PAGE™ Midi (QP3XXX) Gels are suitable for Invitrogen® XCell SureLock® Mini-Cell, Invitrogen® Mini Gel Tank, Hoefer SE260, and other systems.

The DNA Concentrator (Magnetic Beads) can be used to efficiently concentrate DNA/RNA from various samples with low concentration without the need of a DNA vacuum concentrator. Solid Phase Reversible Immobilization (SPRI) magnetic beads are well used for DNA and RNA purification and concentration. The beads are paramagnetic particles coated with carboxyl groups that reversibly bind to DNA and RNA.
The concentrator protocol is simple: mix Concentrator Buffer and Concentrator Beads with the sample, wash, and elute pure DNA in a small volume to concentrate the DNA samples. Moreover, the DNA/RNA samples are also purified during the procedure. The beads with our unique technology purify DNA/RNA samples effectively by removing unwanted components such as dNTPs, enzymes, detergents, proteins, and other contaminants.
However, traditional magnetic beads can only bind nucleic acids that are 100 bp or longer. Nucleic acids shorter than 100 bp are not effectively recovered. We have successfully developed the kit that overcomes the hurdle of short nucleic acids recovery. The reagent can be used for concentration of samples from genomic DNA to short DNA/RNA.
Recovery rate
>90% for DNA size >30 bp
>80% for DNA size between 20-29 bp
Features
Effective concentrator of DNA and RNA samples, even small DNA, RNA, oligos
Binding capacity: 10 ug DNA per prep
Removal of unwanted components and other impurities
