RNase-Free DNase I (bovine pancreas) is an endonuclease useful in removing DNA that might interfere with the characterisation, manipulation, or use of RNA, or for any application requiring highly purified DNase I

BioSearch Tech (Lucigen/Epicentre)

RNase-Free DNase I (bovine pancreas) is an endonuclease useful in removing DNA that might interfere with the characterisation, manipulation, or use of RNA, or for any application requiring highly purified DNase I. It efficiently hydrolyses double- and single-stranded DNA to a mixture of short oligo- and mononucleotides.

Figure 1. DNA removal from in vitro transcription reactions using RNase-Free DNase I. A linearized DNA template was transcribed using T7 RNA polymerase according to standard invitro transcription conditions. Lane 1, kb ladder; Lane 2, DNA control; Lane3, transcription mixture; Lane 4, transcription mixture treated with 1MBU of RNase-Free DNase I for 15 minutes at 37°C.

Unit Definition

Using the standard 50µl assay volume, one Molecular Biology Unit (MBU) digests 1µg of pUC79 DNA to oligodeoxynucleotides in 10 minutes at 37°C in 33 mM Tris-acetate, pH 7.8, 66mM potassium acetate, 10mM magnesium acetate, and 0.5mM DTT 2mM CaCl2.

Storage Buffer

50% glycerol containing 10mM Tris-HCl, pH 7.5, 10mM CaCl2, and 10mM MgCl2.

Quality Control

No degradation of 1µg of a synthetic RNA transcript is detected by agarose gel electrophoresis following incubation with 10U of RNase-Free DNase I at 37°C for 1 hour.

Myeloperoxidase Enzyme Immunoassay Kit 髓过氧化物酶 免疫分析试剂盒 Human MPO EIA KIT FEATURES: USE - Measure human MPO in a variety of matrices SAMPLE -Serum, Platelet-Poor Heparin Plasma, Saliva, Urine or Tissue Culture Media SAMPLES / KIT - 40 in duplicate SENSITIVITY - 0.068 ng/mL STABILITY - liquid reagents stable at 4°C QUICK RESULTS - 2.5 HOURS Myeloperoxidase (MPO) is a tetrameric heme-containing protein abundantly produced in neutrophil granulocytes where it plays an important anti-microbial role. During degranulation MPO is released into the extracellular space. There, as part of the neutrophils “respiratory burst”, it produces hypochlorous acid from hydrogen peroxide and Cl–. MPO also uses hydrogen peroxide to oxidize tyrosine to the tyrosyl radical. Both hypochlorous acid and tyrosyl are cytotoxic and when present can kill bacteria and other pathogens. Hereditary deficiency of myeloperoxidase predisposes individuals to immune deficiency. Studies have shown an association between elevated MPO levels and coronary artery disease, and in 2003 it was suggested that MPO may serve as a sensitive predictor of myocardial infarction in patients complaining of chest pain. Since that time the clinical utility of MPO testing in cardiac patients has been solidly established in the literature with well over 100 papers published. In 2010 this clinical application was further refined by additional studies which determined that measuring both MPO and C-reactive protein (CRP) provided more accurate prediction of mortality risk than measuring just CRP alone.
