MagJET DNA and RNA Purification Kits

Nucleic acid isolation is one of the most fundamental steps in molecular biology applications and is a prerequisite for many experiments. MagJET nucleic acid purification kits utilize magnetic bead–based technology, allowing for highly efficient nucleic acid isolation from a variety of samples at any throughput. MagJET kits provide high-purity DNA and RNA ready to use in routine and demanding downstream applications.

Features & benefits of MagJET Magnetic Bead-Based Purification

MagJET magnetic bead-based technology utilizes proprietary high capacity paramagnetic particles optimized to isolate nucleic acids with superior purity and yields compared to other kits on the market. Due to large total surface area, MagJET magnetic beads exhibit high binding capacity, resulting in superior nucleic acid yields and recovery rates typically exceeding 80%. Uniform bead size and shape ensure robust performance and consistent results with less sample-to-sample variation. MagJET magnetic beads are highly stable in solution and respond rapidly to an applied magnetic field making MagJET nucleic acid purification kits an ideal choice for high-throughput automation.

(A) The automation protocols are optimized for Thermo Scientific Kingfisher instruments where magnetic beads are transferred from well to well during the purification procedure.

(B) In the manual protocol a magnetic field applied by an external source is used to capture the beads against the wall of the tube. The supernatant is removed by aspiration.

Manual and automated workflows were used to purify RNA from N. tabacum leaf samples (each 50 mg) with the MagJET Plant RNA Kit. The Thermo Scientific KingFisher protocol was used for the automated workflow. Isolated RNA was analyzed by agarose gel electrophoresis (1%), M – Thermo Scientific RiboRuler High Range RNA Ladder.
