Bacterial DNA Extraction Kit (Magnetic Beads)
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
100% centrifuge-free
Bacterial cultures can be used directly without centrifuge to pellet the bacteria
Simple magnetic beads method
No centrifuge needed
No column needed
No vacuum needed
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).
The HiPure FastFilter Plasmid DNA Maxi Kits combine the power of HiPure technology with the time-tested consistency of alkaline-SDS lysis of bacterial cells to deliver high-quality DNA. HiPure DNA columns facilitate the binding, washing and elution steps thus enabling multiple samples to be simultaneously processed. This system also includes a special filter cartridge which replaces the centrifugation step following alkaline lysis. Plasmid DNA purified by this system is suitable for automated fluorescent DNA sequencing, restriction endonuclease digestion, transfection of mammalian cells, and other manipulations. Up to 1000 µg high copy number plasmid DNA or 50-500 µg low copy number plasmid DNA can be purified from 200mL overnight culture.

Principle
The HiPure Plasmid procedure is based on alkaline lysis of bacterial cells followed by adsorption of DNA onto silica in the presence of high salt. The unique silica membrane used in the kit completely replaces glass or silica slurries for plasmid DNA minipreps. The procedure consists of 3 basic steps: Preparation and clearing of a bacterial lysate by alkaline method，then transfer the supernatant to column to bind DNA. After washing proteins and other impurities, nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).
Advantages
High purity – purified plasmid can be directly used in sequencing, enzyme digestion and PCR, etc.
Fast – it takes only 15-60 minutes to complete the isolation
Economy – high cost performance

Storage and Stability
The kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. If any precipitates form in the buffers, warm at 37℃ to dissolve. After addition of RNase A，Buffer P1 is stable for 6 months when stored at 2-8°C.

DBCO-C5-PEG12-acid is an analog of DBCO-Acid with PEG linker and a DBCO group. DBCO group is a highly reactive cycloalkyne which is commonly used for copper-free Click Chemistry reactions. The hydrophilic PEG chain allows for increased water solubility of compounds in aqueous media. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. HATU) to form a stable amide bond. Reagent grade, for research use only.
