Chloride form quaternary ammonium functionality.Strongly basic, macroreticular resin of moderately high porosity with benzyltrialkylammonium functionality.

Supplier: Spectrum Chemical

Benzyltriethylammonium Chloride, also known as Triton B, is a quaternary ammonium salt that functions as an organic base and is a popular phase-transfer catalyst.

Supplier: LONZA

Ammonium-Chloride-Potassium (ACK) Lysing Buffer is used to lyse red blood cells in preparations containing white blood cells.

Supplier: Avantor

Avantor® Hichrom Anion/S columns are based on 10 µm silica with quaternary ammonium ion-exchange groups. These columns are optimised for non-suppressed conductivity detection and are best suited for routine separations of chloride, bromide, nitrate and sulphate.

Supplier: G-Biosciences

A red blood cell lysis buffer for the isolation of white blood cells free from interference of RBCs. The optimised concentration of ammonium chloride and enhances effectively lyses red blood cells, while preserving the integrity of the leukocytes.

Supplier: Thermo Fisher Scientific

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.

Indicator tablets for determination of water hardness by titration with EDTA.

Specifications
Minimum weight: ≥ 0.20 g
Maximum weight: ≤ 0.23 g
Disintegration time (at 25°C): ≤ 150 s
Application test: conforms

The tablets are dissolved in 100 ml of the water sample to be tested, which has been buffered at pH 10 with 1 ml of Ammonia/ Ammonium chloride buffer solution, and then titrated with EDTA solution (0,01 M) till the sample turns from red to blue.
Total hardness in mg/l = 10×ml of titrant used.

Control samples of  calcium carbonate should be used to calibrate the method.

Goat IgG fraction to beta-Galactosidase is used in enzyme Immunoassays, fluorescein Immunoassays, blots, cell or tissue immunostaining. Gives sharp precipitation lines in IEP and ID techniques.
The antibody is produced by hyperimmunizing goats with the enzyme beta-galactosidase from Escherichia coli. The IgG fraction is prepared by delipidation, ammonium sulfate fractionation, and anion exchange chromatography, and is further purified by solid-phase absorption to remove antibodies to non-beta-galactosidase E. coli proteins. The product is dialyzed into 0.02M sodium phosphate, 0.14M sodium chloride, pH 7.3, adjusted to standard titer, filtered through a 0.22 μm filter, and vialed. No preservative is added.

Supplier: MP Biomedicals

The IgG fraction is prepared from the specific rabbit antiserum by delipidation, ammonium sulfate fractionation and anion exchange chromatography. The resulting IgG fraction is dialyzed into 0.02M sodium phosphate, 0.14M sodium chloride, pH 7.3, adjusted to standard titer, filtered through a 0.22 µm filter, vialed and lyophilized. No preservative is added.

The total protein is measured using the Biuret procedure, with bovine albumin as a standard. Hemagglutination titer is standardized with an in-house control by measurement of agglutination end-point with 10% human red blood cells. Each IgG fraction is tested for purity at a minimum of 40 mg/ml using immunoelectrophoresis. The product is mostly rabbit IgG; no trace of albumin is detected.
