Sulfo DBCO-TFP Ester is a water-soluble, amine-reactive labeling reagent that enables simple and efficient incorporation of Sulfo DBCO moiety onto amine-containing molecules. The hydrophilic, sulfonated spacer arm greatly improves water solubility of DBCO derivatized molecules, in many cases making them completely soluble in aqueous media. A short spacer arm adds minimal mass to modified molecules.

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
