Opis: Melamine is combined with formaldehyde to produce melamine resin, a very durable thermosetting plastic used in Formica, and melamine foam, a polymeric cleaning product. The end products include countertops, dry erase boards, fabrics, glues, housewares and flame retardants. Melamine is one of the major components in Pigment Yellow 150, a colorant in inks and plastics.Melamine also enters the fabrication of melamine poly-sulfonate used as superplasticiser for making high-resistance concrete. Sulfonated melamine formaldehyde (SMF) is a polymer used as cement admixture to reduce the water content in concrete while increasing the fluidity and the workability of the mix during its handling and pouring. It results in concrete with a lower porosity and a higher mechanical strength exhibiting an improved resistance to aggressive environments and a longer life-time. The use of melamine as fertiliser for crops had been envisaged during the '50s and '60s because of its high nitrogen content (2/3).[7] However melamine is much more expensive to produce than other common nitrogen fertilisers, such as urea. To be effective as a fertiliser, it is essential that the plant nutrients are released or made available in a manner that matches the needs of the growing crop. The nitrogen mineralisation process for melamine is extremely slow, making this product both economically and scientifically impractical for use as a fertiliser.

Opis: Cell proliferation dyes diffuse passively into cells and covalently label intracellular proteins, resulting in long term cell labelling. They are non-fluorescent until they are hydrolysed by intracellular esterase's. The dyes then react with intracellular amines forming fluorescent conjugates that are retained in the cell. Immediately after staining, a single, bright fluorescent population will be detected by flow cytometry. With each cell division, daughter cells inherit roughly half of the fluorescent label, allowing the number of cell divisions that occur after labelling to be detected by the appearance of successively dimmer fluorescent peaks on a flow cytometry histogram compared to cells analysed immediately after staining. Staining is formaldehyde fixable.
