formaldehyde is widely employed in industry for a wide range of applications. It acts as a disinfectant and biocide and is utilized as a tissue fixative and embalming agent. formaldehyde is a key metabolite produced during normal metabolism and contributes to methylation reactions and protein and nucleic acid synthesis. Increased production of formaldehyde has been observed in many cancer cell lines and increased formaldehyde concentration in urine has been associated with bladder and prostrate cancer.

Grace Bio-Labs HybriWell(TM) sealing system seals securely to a microscope slide surface in seconds to accommodate water bath hybridizations such as protein or nucleic acid hybridization assays. The HybriWell fluorescent (HybriWell-fL(TM)) hybridization system has been designed specifically for sensitive DNA microarray assays involving Cy5(R) or Alexafluor(R) 647 direct-labeled DNA probes.featuresEncloses a single or multiple specimens in a small reagent volume and eliminate evaporation. Access ports in the chamber surface allow for the addition or removal of reactants. Ports are easily sealed using adhesive seal tabs provided with each order. Sealed chambers are watertight and ideally suited for waterbath incubations. RNase free hydrophobic surfaces will not trap or bind probes. Disposable chamber removes cleanly and easily even after heating.Each package includes illustrated instructions for use applicator and 200 adhesive port seals.
