Varicella zoster virus (VZV) is one of eight herpes viruses known to infect humans and other vertebrates. VZV commonly causes chicken-pox in children and both shingles and postherpetic neuralgia in adults. Primary VZV infection results in chickenpox, which may rarely result in complications including encephalitis or pneumonia. VZV, like other herpes viruses, remains dormant in the nervous system of the infected person, and in 10-20% of cases the VZV reactivates later in life producing a disease known as herpes zoster or shingles. Serious complications of shingles include postherpetic neuralgia, zoster multiplex, myelitis, herpes ophthalmicus, or zoster sine herpete.

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.

.
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.

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.
Trichinellosis is caused by Trichinella spiralis, a parasitic nematode of pork, horse and wild animals. Humans can be infected by eating raw or undercooked meat from infected animals. Most infected people do not show any symptoms. However, in some cases, symptoms appear during intestinal stage (diarrhea and abdominal pain) and muscular stage (muscle pain, fever, edema). Diagnosis is based on signs and symptoms, but in many cases it is not conclusive for the diagnosis. Serological assays have an important place on the final diagnosis of the disease. The ELISA kit has shown appropriate performance for the serological screening of trichinellosis.

Test Principle
The kit provides all the material needed to perform 96 enzyme-linked immunosorbent assays (ELISA) on breakable microtitration wells sensitized with Trichinella spiralisexcreted/secreted (E/S) larval antigens. Specific antibodies in the sample will bind to these antigens and washing will remove unspecific antibodies. The presence of parasite specific antibodies is detected with a Protein A – alkaline phosphatase conjugate. A second washing step will remove unbound conjugate. Revealing bound antibodies is made by the addition of pNPP substrate which turns yellow in the presence of alkaline phosphatase. Color intensity is proportional to the amount of Trichinella spiralis specific antibodies in the sample. Potassium phosphate is added to stop the reaction. Absorbance at 405 nm is read using an ELISA microplate reader. The test can be performed with automatic systems, but this must be validated by the user.
