MutS Homolog 2 (MSH2) is a protein involved in the mismatch-repair pathway. This protein is commonly associated with hereditary non-polyposis colorectal cancer, and mutations in this gene are correlated with the development of sporadic colorectal carcinoma. Expression levels of MSH2 are abnormally low in a high percentage of patients with microsatellite instability, as well as endometrial and ovarian cancers. Use of Anti-MSH2 is optimized when paired in an IHC panel with antibodies against MSH6, MLH1, and PMS2. Reports have shown Anti-MSH2 to be useful in the detection of the protein in a number of normal and neoplastic tissues, and for identifying a loss of MSH2 in tumors that are microsatellite-unstable.

Sample type purification kit guide
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.

These kits provide a fast, reliable and convenient spin column method for the isolation of high quality, high purity and inhibitor-free cell-free circulating DNA (cfc-DNA) from plasma/serum sample. These kits are designed to isolate all sizes of cfc-DNA from either fresh or frozen plasma/serum samples and the purified DNA is eluted into a flexible elution volume ranging from 25 µL to 50 µL. The purified plasma/serum cfc-DNA is fully compatible with all downstream applications including PCR, qPCR, methylation-sensitive PCR and Southern Blot analysis, microarrays and NGS.
Background
Plasma/Serum cell-free circulating DNA (cfc-DNA) has the potential to provide biomarkers for certain cancers and disease states as well as fetal DNA in maternal blood. Currently, significant advancements are being made in utilizing cfc-DNA as biomarkers for the early diagnosis, prognosis and monitoring of therapy for several cancer types and autoimmune diseases. Cell-free mitocondrial DNA (cfmtDNA) is also under investigation for its clinical significance. This cfc-DNA is usually present as short fragments of less than 1000 bp. In addition, cell-free fetal DNA has been widely used as a non-invasive method for prenatal diagnosis including early identification of fetal sex, genetic studies for families at high risk for inherited genetic disorders, screening for Rhesus factor, screening for aneuploidy and identification of preeclampsia.

Storage Conditions and Product Stability
All buffers should be kept tightly sealed and stored at room temperature (15-25°C) for up to 2 years without showing any reduction in performance. Norgen’s Plasma/Serum Cell-Free Circulating DNA Purification Kits contain ready-to-use Proteinase K solution, which is dissolved in a specially prepared storage buffer. The Proteinase K is stable for up to 2.5 years after delivery when stored at room temperature. To prolong the lifetime of Proteinase K, storage at 2–8°C is recommended.
