Omschrijving: Dihydrogen hexachloroplatinate(IV) hexahydrate is used for the determination of potassium. It is also used for the purification of platinum by treating it with ammonium chloride flowed by heating of ammonium hexachloroplatinate with hydrogen yields elemental platinum. It also finds application in catalysis, electroplating, photography, platinum mirrors, printing for etching of zinc, producing fine color in glass and porcelain, indelible ink and microscopy. It is a precursor for the preparation of other platinum catalysts.

Omschrijving: Ammonium acetate is a chemical compound which is derived from the reaction of ammonia and acetic acid. Ammonium acetate is volatile at low pressures. Because of which it has been used to replace cell buffers with non-volatile salts, in preparing samples for mass spectrometry. It is used as a buffer for mobile phases for HPLC with ELSD detection.

Omschrijving: Araldite® is an epoxy resin commonly used for embedding. It is basically free from polymerization damage and the plastic does not sublime in the microscope, hence providing continual support and preservation of fine detail.[1] It is composed of araldite M or CY 212, dodecenyl succinic anhydride, dibutyl phthalate and 2,4,6-tridimethylamine methyl phenol.

Omschrijving: Bromocresol purple (BCP) is an organic dye and a pH indicator. It changes from yellow (pH 5.2) to purple (6.8). BCP reacts with ammonia to yield ammonium salt. Hence, it can be used as an ammonia sensing probe.

Catalogus nummer: (PRSI5049)

Omschrijving: GNPDA1 Antibody: Glucosamine-6-phosphate deaminase (GNPDA) is an allosteric enzyme that catalyzes the reversible conversion of D-glucosamine-6-phosphate into D-fructose-6-phosphate and ammonium. GNPDA1 is one of two mammalian glucosamine-6-phosphate deaminases that are thought to have arisen though gene duplication, with the GNPDA2 protein closer in structure and activity to the E. coli enzyme. GNPDA1 possesses greater affinity for ammonium than either GNPDA2 or the E. coli enzyme suggesting that the forward reaction of D-glucosamine-6-phosphate into D-fructose-6-phosphate and ammonium is catalyzed at a slower rate than GNPDA2.
