DBCO-PEG6-DBCO is a monodisperse click chemistry linker containing two terminal DBCO groups with hydrophilic PEG spacer arm. DBCO will react with azide-bearing compounds or biomolecules to form a stable triazole linkage without copper catalyst. PEG spacer arm can increase water solubility and membrane permability. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

16S V1-V3 Library Preparation Kit for Illumina
Product Info
Document
Product Info
Overview
Protocol optimized for DNA isolated from a diversity of samples including stool, soil, water, saliva, plant, urine, skin, and more
Simple and quick workflow: library could be prepared in less than 5 hours
Component of Norgen’s metagenomics workflow
A single NGS run can be prepared with up to 384 unique dual-index libraries
The 16S V1-V3 Library Preparation Kit for Illumina consists of the reagents and components required for library preparation of the 16S V1-V3 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-V3 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-V3 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-V3 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.
IST-121 QuickSeal qPCR CrystalTM Self Adhesive Sealing Film
Product Info
Document
Product Info
Overview
Optically clear adhesive film with pressure activated adhesive. Seal is peelable; suitable for qPCR and other imaging techniques including crystallization.
Optically clear seal specifically developed for optical applications, particularly qPCR
It is non sticky when removed from the packaging; this aids handling when wearing gloves
The adhesive is contained within small capsules, allowing light to pass through to ensure the optical clarity of the seal
When the seal is in position, pressure can be applied to burst the capsules, releasing a strong adhesive only where the seal touches the raised well rims of the plate – the rest of the seal area above the wells remains optically clear
For all adhesive seals, the best sealing results are achieved using our Hand Roller or KAPS 500 Auto Sealer

Protease K is a serine protease with high enzymatic activity and wide substrate specificity. It can preferentially decompose ester and peptide bonds adjacent to the ends of hydrophobic amino acids, sulfur-containing amino acids and aromatic amino acids C, and is often used to degrade proteins to produce short peptides. It has the typical catalytic triad Asp39-His69-Ser224 characteristic of serine proteases and two Ca2+ binding sites around the active center increase its stability, allowing it to maintain high enzyme activity under a wider range of conditions.
