VWR® Taq DNA Polymerase is an ultra-pure, thermostable, recombinant DNA polymerase, which provides robust PCR performance in a wide range of PCR applications, without time-consuming optimisation. The enzyme is isolated from Thermus aquaticus, and has a molecular weight of approximately 94 kDa. VWR® Taq DNA Polymerase has both a 5' to 3' DNA polymerase and a double strand 5' to 3' exonuclease activity. It leaves an A overhang, which makes the enzyme ideal for TA cloning.

X-Gal is a chromogenic substrate for ß-Galactosidase that forms an intense blue precipitate. Used in conjunction with IPTG in a colorimetric assay, X-Gal allows differentiation of recombinants from non recombinants in cloning experiments with vectors containing the lacZ gene. It is also used in microbiology to detect microorganisms which have ß-Galactosidase activity.

This product adsorbs water vapour, so maintaining a dry environment for your products. When the gel's adsorption capacity is exhausted the colour changes from orange to colourless. The product can be regenerated back to an orange colour by heating in a drying oven at 120 to 140 °C for approximately 3 hours and then re-used. It is suitable for numerous drying applications, although it is not recommended for strongly acidic or strongly alkaline compounds.

Solvent replacement for cleaning instruments and equipments in contact with paraffin wax. Paraffin wax is used to prepare histological sections for microscopy, but it is very difficult to remove its residuals on microtomes and other laboratory surfaces. Clean-Lab has been created to make the removal of paraffin very easy and quick.
