The L-Arginine/Urea/Ammonia test kit is specific and a rapid measurement and analysis of L-arginine, urea and ammonia in grape juice/must and wine.
Note for Content: The number of manual tests per kit can be doubled if all volumes are halved. This can be readily accommodated using the MegaQuantTM Wave Spectrophotometer (D-MQWAVE).

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.
