Propargyl-PEG1-acid

Description

Ultrapure dUTP (2´-Deoxyuridine, 5´-Triphosphate) supplied as sodium salt in purified water (pH 8.5).  dUTP can be used in place of dTTP in PCR and RT-PCR protocols to prevent carryover from previous amplifications. The substitution of dUTP for dTTP in PCR results in uracil-containing PCR products that are suitable for most standard applications. The enzyme uracil-N-glycosylase (UNG, also referred to as UDG) can be added to a PCR premix to excise uracil from any contaminating PCR product, thereby preventing false positives. Each lot of dUTP is tested to ensure specific DNA amplification and the absence of nuclease activity. 

Features

• Ideal for PCR amplification and cDNA synthesis
• Nuclease and ribonuclease free

Applications

• PCR
• Avoid carryover contamination between PCRs to eliminate a source of false positives.

Storage

-20°C for 36 months

Overview

Perforated heat sealing film which is optically clear. This seal has 3 mm slits for gas transfer; is suitable for insect studies and seed storage too.

• Heat sealing is a quick and cost effective method of plate sealing
• Our ClearASeal Perf Heat Seal is based on our ClearASeal Peel, with the addition of 3 mm slits across the width of the seal
• These slits render the seal gas permeable, whilst retaining evaporation to a minimum, compared to the use of lids
• The ClearASeal Perf Heat Seal is compatible with polypropylene, polyethylene, polystyrene and cyclic olefin copolymer (COC) plates
• The Seal has a wide seal integrity temperature range, from -80 °C to 110 °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

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.

Key Features

• 3’-5’ exonuclease specific for single stranded DNA
• High activity at 25 – 37°C
• Easily heat-inactivated by 1 min incubation at 80°C, or 15 min at 60°C
• Moderate salt tolerance

Application

Removal of primers post-PCR prior to DNA sequencing or SNP detection
