Heat-Labile Exonuclease I (HL-ExoI) is a 3’ – 5’ exonuclease, specific for single stranded DNA. The enzyme is recombinantly produced in E. coli. HL-ExoI is active at 25 – 37°C and inactivated by 1 minute incubation at 80°C or 15 minutes at 60°C.

OverView
Heat-Labile Exonuclease I (HL-ExoI) is a 3’ – 5’ exonuclease, specific for single stranded DNA. The enzyme is recombinantly produced in E. coli. HL-ExoI is active at 25 – 37°C and inactivated by 1 minute incubation at 80°C or 15 minutes at 60°C.
HL-ExoI is used for degradation of ssDNA such as primers and oligos. It is also ideal for treatment of sensitive samples and useful in the development of novel molecular diagnostics applications.

Quality Control
ArcticZymes is dedicated to the quality of our products. We manufacture all products at our ISO 13485 certified facility in Norway.
Nucleic acid testing (NAT) is the method of choice for detection and quantification of a wide range of micro organisms. Primerdesign manufactures and supplies high quality quantitative real-time PCR kits for the detection and simultaneous quantification of numerous significant pathogens . A copy number standard curve is provided for quantification and an the internal extraction template (DNA or RNA), controls for the quality of the nucleic acid extraction and eliminates false negative results.
The kit is designed with the broadest possible detection profile to ensure that all clinically relevant strains and subtypes are detected. Target sequences are selected by working with data from key opinion leaders in the field. Multiple sequence alignments and unprecedented real-time PCR expertise in design and validation ensure the best possible kit.
Details of the target and priming specificity are included in the individual handbooks above.
Packaged, optimised and ready to use. Expect Better Data.

Isolates all sizes of exosomal and extracellular vesicle RNA, including microRNA.
Bind and elute all RNA irrespective of size or GC content, without bias.
No phenol extractions.
No Proteinase K treatment.
No carrier RNA.
Concentrate isolated RNA into a flexible elution volume ranging from 50 μL to 100 μL.
Purify high-quality RNA in 15-20 minutes.
Purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing.
Purification is based on EXTRAClean spin column chromatography that uses Norgen’s proprietary separation matrix.
The kit is designed to isolate all sizes of RNA, including microRNA. The kit provides a clear advantage over other available kits in that it does not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, the kit allows the user to elute into a flexible elution volume ranging from 50 μL to 100 μL. The purified RNA is of the highest integrity, and 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.

Storage Conditions and Product Stability All buffers should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment. It is recommended to warm Lysis Buffer A for 20 minutes at 60°C if any salt precipitation is observed.
Actin is part of the cytoskeletal system of all cell types. Smooth Muscle Actin is found in myofibroblasts and myoepithelium, but not in cardiac and skeletal muscles. Labelling of smooth muscle actin in concert with muscle specific actin staining can allow for differentiation between rhabdomyosarcoma and leiomyosarcoma, as Muscle specific actin is found in rhabdomyoblasts, while smooth muscle actin is found in leiomyosarcomas.
