DBCO-PEG6-NHS ester is a click chemistry PEG reagent containing NHS ester that is able to react specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. The hydrophilic PEG spacer arm improves water solubility and provides a long and flexible connection that minimizes steric hindrance involved with ligation. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Attogene has developed the first of its kind and patent pending technology that uses a novel RNA substrate tagged on the 5′ and 3′ end with a Biotin that is attached to our streptavidin colloidal gold reporter molecules and a test line tag. In the absence of RNases, the gold tagged RNA molecule will flow up the lateral flow strip and bind to the test line using an anti tag antibody (INDICATING that NO RNase is detected). When RNases are present, however, the RNA substrate is cleaved, and the 5′ and 3′ tags are spatially separated in solution cauing the test line to disapear.
This test can be used to rapidly and efficiently detect ribonucleases in both liquid and on solid surfaces and a perfect tool for monitoring mRNA vaccine manufacturing.
RNase activity in a convenient and sensitive colormetric assay that delivers results in real time. Great for Quality Testing for RNase contamination of materials and supplies.
The NGS Single Stranded DNA Library Prep Kit (illumina platform) was developed for construction of high quality libraries using sheared single stranded DNA (50 ng – 500 ng) as input. The kit is ideal for making NGS libraries with samples of denatured DNA, viral DNA, highly degraded ancient DNA and other single stranded DNA. The workflow of the ssDNA kit is simple: make the libraries in two steps followed by PCR and cleanup steps. The libraries will be ready in just 1.5 hours with a 10 minutes of hands-on time. The library pooling is possible dependent on the type of index. The final library is strand specific.
NGS Single Stranded DNA Library Prep Kit workflow
Three index types are available for the kit:
Non-index (Cat.# 30081): Libraries do not have index.
Index(Cat.# 30082): Each of the index primers has a unique 6-base index sequence that can be used to identify libraries. ssDNA library multiplexing is up to 48 samples. Index information can be downloaded here.
Unique dual index (Cat.# 30083): ssDNA sample multiplexing up to 96 libraries is possible with unique dual indexes. We have developed a Four-Base Difference Index System. This makes it possible to generate indexes with at least 4 bases different from each other in the 8 bases index length. The unique dual indexing primers remove NGS errors (example: de-multiplexing errors, read mis-assignment, index hopping etc). Index information can be downloaded here.
Kit advantages:
NGS Single Stranded DNA Library Prep Kit has similar library conversion efficiency and yield as compared to a regular DNA library prep kit.
Alignment rate and duplication rate: comparison of single stranded DNA library kit versus double stranded DNA library prep kit.
