The Bacterial DNA Extraction Kit (Magnetic Beads) was developed for the bacterial genomic DNA extraction from bacterial cultures directly using magnetic beads from a wide variety of gram-negative and gram-positive bacterial species, as well as yeast and other fungi. With our proprietary magnetic beads technology, the kit eliminates the tedious centrifuge steps for columns. The kit provides a reliable and simple approach for high-quality bacterial DNA isolation with fast magnetic response time and high binding capacity.
Bacteria are the most diverse and abundant small single-celled organisms and are vital to the planet’s ecosystems. Some bacterial species are pathogens that can cause a variety of diseases to humans and animals. Besides their ecological and biomedical importance, bacteria are also used in biotech and pharmaceutical applications such as production of enzymes, DNA preparation, biofuels, food research, and chemical production.
Bacterial cells are grown to log-phase and the culture is lysed directly with a lysis buffer, then mixed with beads to bind genomic DNA. After wash steps, genomic DNA is eluted in Low TE or TE Buffer. The isolated genomic DNA with the magnetic beads is free of contamination such as RNA, proteins, salts, and other impurities. Bacterial DNA extracted using the kit is suitable for downstream applications such as qPCR, PCR, DNA sequencing, Southern Blotting, molecular cloning, DNA hybridization, restriction enzymatic digestion, and Next-generation Sequencing (NGS) etc.
Features
Purified genomic DNA from various bacteria were isolated with the Bacterial DNA Extraction Kit. A portion of the extracted genomic DNA was loaded on a 1% agarose gel. DNA ladder: BioDynami 1 kb Plus DNA Ladder (Cat.# 10005L).
These kits provide a fast, reliable and convenient method to sequentially isolate and concentrate exosomal RNA as well as Free-Circulating RNA from different plasma/serum sample volumes. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. These kits are designed to isolate all sizes of RNA, including microRNA as well as all sizes of the free-circulating protein-bound RNA, including microRNA. These kits provide a clear advantage over other available kits in that they do not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, these kits allow the user to elute into a flexible elution volume ranging from 50 µL to 100 µL. The RNA isolated from the purified exosomes is free from any protein-bound circulating RNA and is of the highest integrity. Moreover, the free-circulating, protein-bound, RNA is free from any exosomal RNA. The purified RNA can be used in a number of downstream applications including real time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.

Storage Conditions and Product Stability
All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment. It is recommended to warm Lysis Buffer A for 20 minutes at 60°C if any salt precipitation is observed.
Important Note
This kit is suitable for the purification of exosomes from fresh or frozen serum or plasma prepared from blood collected on either EDTA or Citrate. Plasma samples prepared from blood collected on heparin should not be used as heparin can significantly interfere with many downstream applications such as RT-PCR.
