DBCO-PEG12-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.

Norgen’s Cell Culture Media Exosome Purification and RNA Isolation Kits constitute an all-in-one system for the purification of exosomes and the subsequent isolation of exosomal RNA from different cell culture media sample volumes. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. The kit is designed to isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias. These kits provide a clear advantage over other available kits in that they do not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, the kits allow the user to elute into a flexible elution volume ranging from 50 µL to 100 µL. The RNA isolated from the purified exosomes is free from any protein-bound circulating RNA and is of the highest integrity. The purified RNA can be used in a number of downstream applications including real time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.

The NGS DNA Fragmentation & Library Prep Kit (illumina and MGI Platforms) was developed for construction of high quality libraries for next generation sequencing. The kit uses intact genomic DNA (EDTA-free DNA or DNA resuspended in TE buffer) as input DNA without an additional DNA fragmentation step. Our technology provides a fast and simple workflow. DNA libraries can be generated around 2 hours with only 10 min hands-on time. Library multiplexing is possible.
NGS DNA Fragmentation & Library Prep Kit Workflow
The incorporation of DNA fragmentation in the kit makes it possible to directly use intact genomic DNA as input DNA without the need of mechanical DNA shearing or enzymatic DNA fragmentation. The NGS DNA Fragmentation & Library Prep Kit does not generate sequencing bias as compared to library using mechanical sheared DNA as input. Sequence coverage is also consistent between enzymatic shearing and mechanical shearing. The library size is inversely correlated with the incubation time of step 1 at 20°C.
Three index types are available for the kit of the illumina platform:
Non-index (Cat.# 30026): Libraries do not have index.
Index (Cat.# 30028): Each of the index primers contains a unique index sequence of 6 bases. Library multiplexing for 48 samples is possible. Index information can be downloaded here.
Unique dual index (Cat.# 30030): Library multiplexing for 96 samples is possible. With the unique features of our 4-Base Difference Index System, the index sequence is 8-base long and each index has 4 bases different from others. Our unique dual index primers effectively identify sequencing errors such as index hopping, mis-assignment of reads, and de-multiplexing errors etc. The unique dual index primers set consists of 96 pre-mixed unique pairs of index primers. Index information can be downloaded here.
Indexes are available for the MGI platform kits (Cat.# 34028).
Kit features:
Library conversion efficiency: 100 ng, 300 ng and 500 ng of intact genomic DNA were used as input.
The library size is inversely correlated with the incubation time of step 1 at 20°C.

Mycobacterium tuberculosis is a pathogenic bacterial species belonging to the genus Mycobacterium, and is the causative agent of tuberculosis. Tuberculosis (TB) is a multifaceted disease and challenging public health problem in both industrialized and developing countries. According to the WHO, 8.8 million active cases of TB are diagnosed each year and of these, almost 2 million die. Once thought to be under control or even close to extinction, TB infection levels are rising and the threat is compounded by new, virulent and drug-resistant strains. Although most cases occur in the developing world (22 countries accounting for 80% of all global cases), increasing population mobility combined with facility of transmission means that no country is immune from the resurgence of TB. TB control programs are currently facing a number of constraints. Worldwide, fewer than 25% of all tuberculosis cases are detected. Of utmost concern is the absence of a timely and accurate test for the diagnosis of mycobacterial disease. Early diagnosis is crucial for the prevention of further spread of the disease.

Storage Conditions and Product Stability
All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
