• Simple and quick workflow: library could be prepared in less than 5 hours
• Component of Norgen’s metagenomics workflow
• A single NGS run can be prepared with up to 384 unique dual-index libraries

Sample type purification kit guide 

The 16S V1-V3 Library Preparation Kit for Illumina consists of the reagents and components required for library preparation of the 16S V1-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 V1-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 V1-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.

Introduction

The HiPure Plasmid EF Maxi Kit combines the power of HiPure technology with Magen’s innovative endotoxin removal technology (ETR) to deliver high-quality plasmid DNA with low endotoxin levels for use in eukaryotic transfection, and in vitro experiments. Up to 1000 µg high copy number plasmid DNA or 200 µg low copy number plasmid DNA can be purified from 150 mL 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 – silica gel column purification is much faster than ion exchange
• High yield – up to 1.5mg plasmid can be binded in one column
• Ultra low endotoxin – content of endotoxin is less than 0.1 EU/μg, which can be directly used for cell transfection and animal injection, etc.
