HL-dsDNase is especially developed to remove contaminating genomic DNA from RNA preparations. Figure 1 shows that HL-dsDNase can reduce 50 ng of human gDNA to levels non-detectable by qPCR. In figure 2, a human total RNA sample was treated with HL-dsDNase and analysed on the Bio-Rad Experion™ System. The results indicate that HL-dsDNase has minimal impact on RNA quality and quantity.
HL-dsDNase is an engineered version of dsDNase that is rapidly and completely inactivated by incubation for 5 minutes at 58°C with 1 mM DTT at pH 8.0 or above. Chemical inactivation in downstream compatible RT or PCR buffers allows milder heat inactivation and, in some cases, skipping heat inactivation altogether. This makes HL-dsDNase very useful for removal of DNA from RNA preparations since the enzyme may be inactivated using various strategies with reduced risk of auto-degradation of RNA in the presence of magnesium, making HL-dsDNase an ideal enzyme when working with small volumens of RNA.
HL-dsDNase is also an excellent choice for removal of unwanted external DNA from samples prior to analysis of nucleic acids protected by biological membranes, e.g., bacteria, viruses, and sperm. Especially if using downstream analysis methods that might be affected by host cell DNA, as metagenomic sequencing and STR-profiling. The easy inactivation of HL-dsDNase makes it a fast and efficient alternative to methods as differential extraction, where sample material is often lost.

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.
