Description générale

Each capsule contains 500 units of glucose oxidase (Aspergilus niger), 100 purpurogallin units of peroxidase (horseradish), and buffer salts. The reaction produces oxidized o-Dianisidine, which is brown. The intensity of the brown color measured at 425-475 nm is proportional to the original glucose concentration.

Application

PGO Enzymes preparation has been used:

in diet sampling and chemical analyses[1][2]
to determine plasma and follicular fluid glucose levels[3]
to measure glucose content in fractions of retrograded debranched rice starch[4]

Tested and found suitable for use in the quantitation of glucose.

Actions biochimiques/physiologiques

PGO Enzymes are used for the quantitative, enzymatic determination of glucose in aqueous solutions such as serum. The reactions are normally monitored at 425-475 nm utilizing o-dianisidine as a colorimetric substrate. Glucose oxidase methods eliminate the effects of interfering substances. Contents of one capsule includes 100 units peroxidase and 500 units glucose oxidase and buffer salts.

Notes préparatoires

The PGO enzymes solution is prepared by adding the contents of 1 capsule of PGO enzymes to 100 mL of water in an amber bottle. Bottle should be inverted several times with gentle shaking to dissolve. PGO Enzymes solution should be stored at 2-8 °C. The solution is stable for up to 1 month unless turbidity develops, and for at least 6 months at –20 °C.

Effects of prepartum diets supplemented with rolled oilseeds on calf birth weight, postpartum health, feed intake, milk yield, and reproductive performance of dairy cows.

R Salehi et al.

Journal of dairy science, 99(5), 3584-3597 (2016-03-14)

The objectives were to determine the effects of supplemental fat (no oilseed vs. oilseed) during late gestation and the source of fat (canola vs. sunflower seed), on dry matter intake (DMI), plasma metabolite concentrations, milk production and composition, calf birth

Inclusion of wheat and triticale silage in the diet of lactating dairy cows.

M T Harper et al.

Journal of dairy science, 100(8), 6151-6163 (2017-06-12)

The objective of this experiment was to partially replace corn silage with 2 alternative forages, wheat (Triticum aestivum) or triticale (X Triticosecale) silages at 10% of the diet dry matter (DM), and investigate the effects on dairy cow productivity, nutrient
