The NGS DNA Fragmentation & Library Prep Kit (ion torrent platform) was developed for construction of high quality libraries for next generation sequencing for ion torrent platform. The kit uses intact genomic DNA (both EDTA-free DNA and DNA in TE buffer are compatible) as input DNA without an additional DNA fragmentation step. Our NGS kit has a fast and simple workflow with only three step. In addition,  all steps can be performed in one tube. The DNA libraries can be generated within one hour with less than 10 minutes of  hands-on time. Library multiplexing up to 12 samples is possible.

NGS DNA Fragmentation & Library Prep Kit Workflow

The incorporation of DNA fragmentation in the kit makes it possible to directly use intact genomic DNA as input DNA without the need of mechanical DNA shearing or enzymatic DNA fragmentation. The protocol is optimized to generate libraries from 200 bp to 500 bp in size. The library size is inversely correlated with the incubation time of step 1 at 20°C.

Kit features:

• • • Fast: 1-hour library construction from intact genomic DNA to NGS library
    • • Total time: 1 hr
      • Hands-on time: 5 min
    • Intact genomic DNA can be used directly as input; DNA fragmentation is not required.
    • Works with both EDTA-free DNA samples and DNA samples in TE buffer
    • Simple workflow
    • • Three steps
      • Only one beads purification step
    • Guaranteed quality: high library conversion efficiency based on our chemistry

Library conversion efficiency for NGS DNA Fragmentation & Library Prep Kit (Ion Torrent Platform). 100 ng, 300 ng and 500 ng of DNA were used as input.

Introduction

Intended Use

For the detection of Salmonella spp. in food, animal feed and in environmental samples from the food production area as described in ISO 6579-1:2017.

Principle and Interpretation

Meat extract and casein provide a source of nitrogen and amino acids and sodium chloride maintain theosmotic balance. Ox bile and brilliant green act as selective agents against non-target microorganisms. Tetrathionate is generated from the sodium thiosulfate. Iodine and calcium carbonate buffer the sulfuric acid generated from tetrathionate reduction.

Formulation

Ingredients	/liter
Meat extract	4.3g
Enzymatic digest of casein	8.6g
Sodium chloride	2.6g
Calcium carbonate	38.7g
Sodium Thiosulfate (anhydrous)	30.4g
Ox bile	4.78g
pH8.0±0.2 at 25°C

Preparation

Suspend 89.4g in 1 L of purified water. Heat with frequent agitation and boil to completely dissolve the powder. Distribute into flasks，and then cool to below 45°C. Add a vial of novobiocin sodium salt (SR0640), a vial of iodine solution and a vial of brilliant green (SR0040) into 100 mL of base medium. Mix thoroughly.

Quality Control

Cultural characteristics observed after incubation at 35-37°C for 24 hours

Quality control strains	Approx. Inoculum(CFU)	Expected Results
Salmonella typhimurium  ATCC14028	10 – 100	≥ 10 cfu on XLD
Escherichia coli  ATCC25922	> 104	≤100 cfu on TSA
Enterococcus faecalis ATCC29212	> 104	<10 cfu on TSA

Storage and Shelf Life

2-30℃，Keep container tightly closed, avoid direct sunlight.

Use before expiry date on the label.

 Precautions

1. When weighing the dehydrated medium, please wear masks to avoid causing respiratory system discomfort

2. Keep container tightly closed after using to prevent clumping.

Waste Disposal

Microbiological contamination was disposed by autoclaving at 121°C for 30 minutes.
