Overview

Peelable heat sealing film which is made using gas permeable grid lacquer paper. This seal is suitable for insect studies and seed storage.

• Heat sealing is a quick and cost effective method of plate sealing
• Our Gas PermASeal II Heat Seal is a paper with a grid lacquer coating which is porous and gas permeable
• The Gas PermeASeal II Heat Seal is compatible with polypropylene, polyethylene, polystyrene and cyclic olefin copolymer (COC) plates
• The seal can be removed by peeling, or it can be pierced with a pipette tip manually or using a liquid handling robot
• The Seal has a temperature range from -20°C to 80°C
• It can be used for insect and seed storage, as it enables gas exchange, whilst providing an inert surface with no adhesive to interfere with the well contents
• This seal is available as sheets, for use with manual and semi-automated sealers, such as our HeatASeal 500 Sealing Machine
• Also available in roll format compatible with specified automated heat sealers, such as our Wasp or Chameleon XT

Overview

• Convenient optimized on-column DNase treatment using Norgen’s RNA Purification Kits
• Also includes protocol for digestion in-solution followed by RNA Clean-Up
• Guaranteed RNase-Free
• Includes Enzyme Incubation Buffer
• Cat. 25710 contains one vial of 1,600 units and Cat. 25720 contains 4 vials (1,600 units/vial)

Norgen’s RNA purification kits isolate total RNA with minimal amounts of genomic DNA contamination. However, for some sensitive downstream applications, it may be desirable to remove all traces of residual DNA. Norgen’s RNase-free DNAse I Kit, with Enzyme Incubation Buffer, can be used for optional on-column DNase digestion with any of Norgen’s RNA purification kits. Alternatively, after isolating total RNA using one of Norgen’s RNA purification kits, the RNA elution can be treated with this DNase I. The RNA can then be purified from the DNase using Norgen’s RNA Clean-Up and Concentration Kit (Cat# 23600), and the RNA can then be used in downstream applications.

Details

Each RNase-Free DNase I Kit is supplied complete with sufficient enzyme and enzyme incubation buffer for 50 or 200 reactions.

Storage Conditions
The DNase I provided is in lyophilized form. It is stable for at least 3 months if stored at room temperature. However, it is recommended to store the DNase I vial at 2 – 8ºC (or below) upon receipt to maintain stability beyond 3 months. Buffer DR and Enzyme Incubation Buffer can be stored at room temperature. After reconstitution with Buffer DR (see product manual), the DNase I should be stored at -20ºC. All reagents should remain stable for at least 1 year in their unopened containers at the appropriate storage temperature.
