First, glucose oxidase catalyzes the formation of gluconic acid and hydrogen peroxide from the oxidation of glucose. A second enzyme, peroxidase, catalyzes the reaction of hydrogen peroxide with potassium iodide chromogen to oxidize the chromogen to colors ranging from blue through greenish-brown, and brown to dark-brown.   Reactivity of the test decreases as the specific gravity and/or pH of urine increases, and may also vary with temperature. Ascorbic acid (more than 50 mg/dl) and ketone bodies (more than 40 mg/dl) may cause a false negative result for a specimen containing a small amount of glucose (100 mg/dl). However, the combinations of such ketone levels and low glucose levels are metabolically improbable. Protein This test is based on the color change of the indicator tetrabromophenol blue. A positive reaction is indicated by a color change from yellow through green and then to greenish-blue. The minimum sensitivity of this test is 10 mg/dl of protein in urine. Highly buffered alkaline urines (pH 9) may give false negative results. The interpretation of results is also difficult in turbid urine specimens.   We have built 100,000 rank purification workshop according to GMP standard.       Certification of company     Packing information:                                        unit size: 4cm*4cm*12cm   unit weight: 0.065 kg   specification: 200 bottles/carton   gross weight/carton: 14 kg   carton size:50cm*50cm*26cm   Shipment                                                              1. We ship goods by UPS/DHL/FEDEX/TNT express which is door to door,takes 3~ 5 days to arrive;       2. We can also help you ship by air cargo which you need to go to Air port to takehome, it takes about 2-7 days to arrive;       3. If goods are large quantity and you not need so urgently ,you can choose by sea to save some freight cost which takes about one month to arrive.       Look forward to cooperate with you.
