The 16S V1-V2 Library Preparation Kit for Illumina consists of the reagents and components required for library preparation of the 16S V1-V2 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-V2 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-V2 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.
Storage Conditions and Product Stability Norgen’s 16S V1-V2 Library Prep Kit for Illumina is shipped as one kit box (for the 24 prep kit) or two sub-component kits (for the 96 prep kit). All kits should be stored at -20°C upon arrival.
All kit components should remain stable for at least 1 year when stored at the specified storage conditions.
For enrichment of bacteria of cosmetics and disposable hygiene products.
Principle:
Casein peptone and soybean peptone provide the nitrogen source, vitamins, and growth factors; sodium chloride to maintain osmotic balance; dipotassium hydrogenphosphate as a buffer; lecithin and Tween 80 can neutralize preservatives and can play a dispersed material in the emulsion features, lecithin can neutralize quaternary ammonium salt, Tween 80 neutralizes phenols, hexachlorophene, formalin, a combination that can neutralize and ethanol.
