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.

RNA/DNA/Protein Purification Plus Kit
This kit provides a rapid method for the high throughput isolation and purification of total RNA, DNA and proteins sequentially from a single sample of cultured animal cells, small tissue samples, blood, bacteria, or yeast. The kit employs two columns: 1) for gDNA purification and 2) for RNA purification utilizing Norgen’s resin columns (superior for the binding of all RNA sizes including miRNA). The proteins are also purified on the second column after RNA elution. The proteins are eluted in buffer and are ready for downstream application without any further clean up required. The proteins can be quantified directly, used in western blots, ELISA or mass spectrometry. This kit provides a rapid spin-column method for the isolation and purification of total RNA, genomic DNA and proteins sequentially from a single sample of cultured animal cells, small tissue samples, blood, bacteria, yeast, fungi or plants.
RNA/DNA/Protein Purification Plus Micro Kit
This kit provides a rapid spin-column method for the isolation and purification of total RNA, DNA and proteins sequentially from a single sample of cultured animal cells, small tissue samples, microdissected samples including LCM, stem cells, sorted cells, and CTC. The total RNA, genomic DNA and proteins are all column purified in less than 30 minutes. The RNA and DNA can be eluted in as little as 20 µL while the protein can be eluted in as little as 50 µL. This kit provides the same performance as if the samples were isolated from dedicated kits.
RNA/DNA/Protein Purification 96-Well Plus Kit
The kit employs two plates: 1) for DNA purification and 2) for RNA purification utilizing Norgen’s resin (superior for the binding of all RNA sizes including miRNA). Please see the protocol schematic below.

Test Principle
The kit provides all the material needed to perform 96 enzyme-linked immunosorbent assays (ELISA) on breakable microtitration wells sensitized with Taenia solium cyst soluble antigens. Specific antibodies in the sample will bind to these antigens and washing will remove unspecific antibodies. The presence of parasite specific antibodies is detected with a Protein A – alkaline phosphatase conjugate. A second washing step will remove unbound conjugate. Revealing bound antibodies is made by the addition of pNPP substrate which turns yellow in the presence of alkaline phosphatase. Color intensity is proportional to the amount of Taenia solium specific antibodies in the sample. Potassium phosphate is added to stop the reaction. Absorbance at 405 nm is read using an ELISA microplate reader. The test can be performed with automatic systems, but this must be validated by the user.
