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.

The series of DNA Size Selection Kits (Magnetic Beads) were developed for DNA size selection using magnetic beads. A total of 11 kits are available, with different selection ranges spanning from 50 bp to over 10 kb. The kits provide a simple and quick approach for the enrichment of a specific range of DNA fragments. The kit workflow allows double-sided or single-sided size selection for specific size cutoffs.

.
DNA size selection is a selective capture of DNA fragments of a specific range of size for next-generation sequencing (NGS) library preparations, PCR, ChIP assay, DNA ligations, endonuclease digestions, adapter removal, and other genomics and molecular biology applications. DNA size selection is preferred after NGS library prep in most of the cases. The NGS library preparation is related to the quality of the sequencing data. Precise NGS library size selection can increase sequencing efficiency, improve data quality, and reduce costs.
There are two types of sequencing technologies: short-read sequencing and long-read sequencing. Short-read sequencing uses DNA libraries that contain small insert DNA fragments of similar sizes, usually several hundred base pairs. The sequencing efficiency can be improved if the DNA size selection is in the right range. Cat.# 20104S and 20104L are the best kits for NGS library size selection of illumina paired-end 100 (PE100) sequencing with 100-200 bp library inserts; Cat.# 20105S and 20105L are the best kits for NGS library size selection of illumina paired-end 150 (PE150) sequencing with 150-300 bp library inserts; and Cat.# 20106S and 20106L are the best kits for NGS library size selection of illumina paired-end 300 (PE300) sequencing with 300-600 bp library inserts.
Long-read sequencing uses a large DNA fragment as input and makes very long reads. Usually, library size selection is preferred to remove smaller fragments. Cat.# 20110S and 20110L are the best kits for long-read sequencing size selection with DNA sizes >5 kb, and Cat.# 20111S and 20111L are the best kits for long-read sequencing size selection with DNA sizes >10 kb.
The magnetic beads technology uses paramagnetic particles, also known as SPRI (Solid Phase Reversible Immobilization) beads, to bind DNA reversibly and selectively. DNA fragments can be size-selected and purified by changing the properties of the magnetic beads or SPRI beads. The magnetic beads can easily separate the beads-binding DNA from the contaminants and unwanted components in the samples. The samples after DNA size selection are free of contaminants such as buffer components, enzymes, proteins, salts, dNTPs, primers, and adapters. Our proprietary magnetic beads reagents improve yield, selectivity, and reproducibility.
Specific DNA fragments at a certain length range can be purified simply using magnetic separation with different beads components, avoiding tedious and time-consuming gel extraction and column-based purification. The magnetic beads method is popular for common DNA size selection, including library size selection. The first beads-binding step, referred to as the right-side clean-up, removes large DNA fragments. The large DNA fragments are bound to the beads and are discarded. The desired DNA fragments in the supernatant are transferred to a new well, and new beads are added to the supernatant for the second beads-binding, referred to as the left-side clean-up. The double-size selected DNA fragments are eluted after ethanol rinsing.
DNA size selection with dual clean-ups.
.
A single clean-up is needed for DNA size selection with large fragments. In this case, only the large DNA fragments are bound to the beads. The selected larger DNA fragments are eluted after ethanol rinsing.

Storage and Stability
DNase I should be stored at -20-8°C upon arrival. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions. The entire kit can be stored at 2-8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.
Purchase Guide
1. When dealing with woody or uncommon samples, R4150 is recommended first. R4150 contains two polysaccharide/polyphenol lysis buffer, which is the most universal product.
2. R4151 is recommended for handling common economic crop samples for the first time. Strong lysis solution can be used to process easy-extraction samples. The amount of corn or rice leaves samples can reach up to 300mg.
3. R4165 adopts CTAB/chloroform method, which can also handle a large number of difficult-to-extraction plants, but requires contact with chloroform substitutes, which is less safe than other kits. This kit uses DNase Ⅰ to remove DNA, which is also a good choice for extracting polysaccharide/polyphenol-rich plant samples.
4. R4014 is recommended for fruit/starch plant samples, which uses improved trizol pre-treatment, single column operation and is more economical.
