Application

Ammonium phosphate dibasic can be used to study x-ray crystallography, biological buffers, optimization reagents, proteomics and protein structural analysis. Ammonium phosphate dibasic has been used in a study for the development and validation of a stability-indicating HPLC method for determination of voriconazole and its related substances. Ammonium phosphate dibasic has also been used to crystallize the native enzyme cellobiohydrolase IB using the hanging-drop vapour-diffusion method.

Crystallization and preliminary crystallographic analysis of the catalytic domain cellobiohydrolase I from Talaromyces emersonii.

Alice Grassick et al.

Acta crystallographica. Section D, Biological crystallography, 59(Pt 7), 1283-1284 (2003-07-02)

Cellobiohydrolase IB is the first native enzyme from the filamentous fungus Talaromyces emersonii to be crystallized. It is a highly thermostable exo-acting enzyme. The native enzyme (MW = 56 kDa) was crystallized using the hanging-drop vapour-diffusion method with ammonium phosphate

Nature-inspired topographies on hydroxyapatite surfaces regulate stem cells behaviour.

Yogambha Ramaswamy et al.

Bioactive materials, 6(4), 1107-1117 (2020-10-27)

Surface topography is one of the key factors in regulating interactions between materials and cells. While topographies presented to cells in vivo are non-symmetrical and in complex shapes, current fabrication techniques are limited to replicate these complex geometries. In this

Effects of nitrogen catabolite repression and di-ammonium phosphate addition during wine fermentation by a commercial strain of S. cerevisiae.

Nathan K Deed et al.

Applied microbiology and biotechnology, 89(5), 1537-1549 (2011-01-20)

Two deletion mutants expected to be defective in nitrogen catabolite repression (NCR) were constructed in a commercial wine yeast background M2: a ure2 mutant and a dal80 gzf3 double mutant. Wild-type and both mutant strains were fermented in Sauvignon Blanc

The nitrogen source impacts major volatile compounds released by Saccharomyces cerevisiae during alcoholic fermentation.

Catarina Barbosa et al.

International journal of food microbiology, 160(2), 87-93 (2012-11-28)

Sulphur-containing amino acids, cysteine and methionine, are generally found in very low concentrations in grape-juice. The objective of this study was to identify the effects of methionine on aroma compounds formation. Nitrogen source effects on growth, fermentative behaviour and aroma

Improvement to the marginal coping fit of commercially pure titanium cast in phosphate-bonded investment by using a simple pattern coating technique.

Anelise Rodolfo Ferreira Pieralini et al.

The Journal of prosthetic dentistry, 108(1), 51-57 (2012-07-07)

Coatings of zirconite, Y(2)O(3) or ZrO(2) on wax patterns before investing in phosphate-bonded investments have been recommended to reduce the reaction layer in titanium castings, but they are not easily obtainable. Spinel-based investments are relatively stable with molten titanium and
