Kindly contacted us inquiring about Glucose mentioned in the protocol booklet for this product. Note: NAD may vary in salt form and degree of hydration. Publishing research using ab136957? When preparing these samples please make sure to keep these on ice throughout the preparation procedure. However because it needs a background blank for each sample (page 9) that means at most there are at most 50-55 samples can be run. Samples were diluted 1-27 fold. Protein concentration for samples varied from 13 mg/mL to 43 mg/mL. This is a mechanism by which the influx of substrate into the glycolytic pathway is controlled.

Record increase in A340 for 3-4 minutes.
Dissolve in Tris⋅MgCl2 buffer, pH 8.0 to obtain a rate of 0.02 - 0.04 ΔA/min. Hexokinases (HK) are found in many organisms including bacteria, plants and mammals and play an important role in glucose metabolism. In this enzymatic method glucose is converted to glucose-6-phosphate (G-6-P) by hexokinase in the presence of ATP, a phosphate donor. All rights reserved.

I was wondering if there is any precaution that needs to be paid attention to regarding the tissue handling after collection and before homogenising them.
Sorry, we can't display this right now. the most specific method for measuring glucose in serum or plasma, wherein hexokinase plus ATP transforms glucose to glucose 6-phosphate plus ADP; glucose 6-phosphate is then reacted with NADP and glucose 6-phosphate dehydrogenase to form NADP which is measured spectrophotometrically. For the best experience on the Abcam website please upgrade to a modern browser such as Google Chrome. In the hexokinase assay protocol, glucose is converted to glucose-6-phosphate by hexokinase. Determine ΔA/min from initial linear portion of curve. Hexokinase Assay Method: The assay is based upon the reduction of NAD + through a coupled reaction with glucose-6-phosphate dehydrogenase and is determined spectrophotometrically by measuring the increase in absorbance at 340 nm. Regarding separate purchase of the kit's developer, I am sorry but this cannot be offered a this time. Hexokinase Activity Assay Kit (ab136957) uses a simple, sensitive and rapid procedure which can detect hexokinase activity to below 0.1 mU/well. Please refer to protocols. Farlex Partner Medical Dictionary © Farlex 2012 For individuals who have a fasting glucose level of 100-125 mg/dL or 5.6-6.9 mmol/L, then this is generally considered to be evidence of prediabetes.
