Spezifität Glucose Assay Kit II provides direct measurement of glucose in various biological samples (e.g., serum, plasma, other body fluids, food, growth media, etc.). In this assay, glucose is specifically oxidized to generate a product which reacts with a dye to generate color (lambda = 450 nm) whose intensity is proportional to glucose concentration. The method is rapid, simple, sensitive, and suitable for high throughput.
This assay is particularly suitable for serum and urine samples since it is unaffected by reducing substances which can interfere with other suppliers offering oxidase-based kits. The assay is also suitable for monitoring glucose level during fermentation and glucose feeding in protein expression processes.
The kit can detect glucose concentrations in the range of 20 ?M - 10 mM.

Testdurchführung

Glucose Assay Protocol:
1. Standard Curve Preparations: Dilute the Glucose Standard to 1 nM/µL by adding 10 µL of the Glucose Standard to 990 µL of Glucose Assay Buffer, mix well. Add 0, 2, 4, 6, 8, 10 µL into a series of wells of a 96 well plate. Adjust volume of all wells to 50 µL with Glucose Assay Buffer to generate 0, 2, 4, 6, 8, 10 nM/well of Glucose Standard.
2. Sample Preparations: Prepare test samples in 50 µL/well with Glucose Assay Buffer in a 96-well plate. If using serum sample, serum (0.5-2 µL/assay. Normal serum contains approx. 5 nM/µL glucose) can be directly diluted in the Glucose Assay Buffer. It is recommended to deproteinate samples by centrifugation using a 10 kDa spin column (ABIN413915) to remove enzymes and interfering proteins. For unknown sample, we suggest testing several doses of your sample to make sure the readings are within the standard curve range.
3. Glucose Reaction Mix: Mix enough reagents for the number of assays to be performed: For each well, prepare a total 50 µL Reaction Mix containing: 46 µL Glucose Assay Buffer 2 µL Glucose Enzyme Mix 2 µL Glucose Substrate Mix
4. Mix well. Add 50 µL of the Reaction Mix to each well containing the Glucose Standard and test samples. Mix well.
5. Incubate the reaction for 30 minutes, protect from light.
6. Measure absorbance at 450nm in a microplate reader.

Ergebnisberechnung

Correct background by subtracting the value derived from the 0 glucose control from all readings (Note: The background reading can be significant and must be subtracted from sample readings). Plot the standard curve. Apply the sample readings to the standard curve. Glucose concentrations of the test samples can then be calculated: C = Sa/Sv (nM/µL or µM/mL, or mM) Where Sa is sample amount (in nmol)calculated from standard curve. Sv is sample volume (in µL) added into the sample wells.
