Sample type purification kit guide
The 16S V2-V3 Library Preparation Kit for Illumina consists of the reagents and components required for library preparation of the 16S V2-V3 amplicon libraries to be used for next-generation sequencing on Illumina platforms. All molecular reagents including primers, enzyme mixes, indexes, and buffers are provided. Instructions for PCR clean up with the AMPure XP Magnetic Beads (supplied by customer) are also included for rapid purification of nucleic acid products generated at two steps of the workflow. The library prep workflow could be used for purified DNA inputs from different sources including stool, soil, water, saliva, plant, urine, skin swab, vaginal swab, cheek swab, nasal swab, plasma/serum, tongue swab, gum swab, and others.
The 16S V2-V3 Library Preparation Kit for Illumina has a streamlined procedure that reduces the handling time such that the library prep procedure can be completed in approximately 4 hours (see diagram below). Input DNA is first subjected to targeted PCR to amplify the V2-V3 region of the DNA encoding 16S rRNA. The post-PCR reaction is then cleaned up using AMPure XP beads. Dual index primers are then added using a limited-cycle PCR. The indexed amplicons flanked by 5′ and 3′ barcoded adaptors are then cleaned using AMPure XP beads. The libraries are then ready for quantification, pooling and sequencing.

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).
