Propargyl-PEG7-NHS ester contains a propargyl group and an NHS ester. As an amine reactive reagent, this product can be used for derivatizing peptides, antibodies, amine coated surfaces etc. In the presence of copper catalyst, propargyl group reacts with azide to yield a stable triazole linkage. The PEG units help increase the hydrophilicity of the reagent. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Sample type purification kit guide
The 16S V3-V4 Library Preparation Kit for Illumina consists of the reagents and components required for library preparation of the 16S V3-V4 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 V3-V4 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 V3-V4 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.
| Minimum amount of starting material: | 2.5 µL of DNA (5 ng/µL) |
| Time to complete library preparation: | 4 hours |
Storage Conditions and Product Stability
Norgen’s 16S V3-V4 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.

Norgen’s EXTRAClean Urine Exosome Purification and RNA Isolation Mini Kit constitutes an all-in-one system for the purification of exosomes and the subsequent isolation of RNA from different urine sample volumes ranging from 250 μL to 1 mL. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. The EXTRAClean columns undergo stringent processing and rigorous quality control measures to minimize contamination traces, ensuring optimal results for sensitive applications such as NGS. The kit is designed to isolate all sizes of RNA, including microRNA. The kit provides a clear advantage over other available kits in that it does not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, the kit allows the user to elute into a flexible elution volume ranging from 50 μL to 100 μL. The purified RNA is free from any protein-bound circulating RNA and of the highest integrity. The purified RNA can be used in a number of downstream applications including real time PCR, reverse transcription PCR, NGS application, Northern blotting, RNase protection and primer extension, and expression array assays.
