Spezifität Glucose-6-phosphate Assay Kit is a simple, sensitive and rapid means of quantifying G6P in a variety of samples. In the assay, glucose-6-phosphate is oxidized with the generation of a product which is utilized to convert a nearly colorless probe to an intensely colored product with an absorbance at 450 nm. The Glucose-6-phosphate Assay Kit can detect G6P in the range of 1 to 30 nmoles with detection sensitivity approx. 10 ?M of G6P.
Produktmerkmale Glucose-6-Phosphate (G6P) Assay Kit: Colorimetric Assay to Quantify G6P in a variety of Biological Samples such as Tissue, Cells etc. within 40 min. Rapid, Convenient & Sensitive.

Substanzklasse Chemical
Hintergrund Glucose-6-phosphate (G6P) is a key sugar intermediate for glucose to get into cells, and then enter either metabolic pathways or storage. G6P can enter the glycolytic pathway, the pentose phosphate shunt or be stored as glycogen or starch. G6P is utilized by its dehydrogenase to generate reducing equivalents in the form of NADPH. This is particularly important in red blood cells where a G6PDH deficiency leads to hemolytic anemia.
Applikationshinweise The Glucose-6-phosphate Assay Kit can detect G6P in the range of 1 to 30 nmoles with detection sensitivity ~10 μM of G6P.

Protokoll 1. Sample Preparation: Liquid or solution samples can be assayed directly. For tissue or cell samples: 10-100 mg tissue or 5 million cells should be rapidly homogenized with 2-3 volume of ice cold PBS or other buffer (pH 6.5-8). Centrifuge at top speed for 10 min to remove insoluble materials. Add 1-50 µL samples into duplicate wells of a 96-well plate and bring volume to 50 µL with Assay Buffer. For unknown samples, we suggest testing several doses of your samples to ensure readings are within the standard curve range. Notes: A. Enzymes in sample may convert or consume G6P. We suggest to deproteinize samples using a perchloric acid/KOH protocol or 10 kd molecular weight cut off spin filter to remove enzymes. Samples may be homogenized in perchloric acid, then neutralize with 10N KOH to minimize G6P conversion. For tissues or cells containing low level of free G6P (5-60 μM), try to minimize sample dilutions. B. NADH or NADPH in samples will generate background readings. If NADH or NADPH is in your sample, you may do a background control (omit G6P Enzyme Mix from the reaction mix) to read the background, then subtracted the background from G6P readings.
2. Standard Curve Preparations: Dilute the G6P Standard to 1 nM/µL by adding 10 µL of the 100 nM/µL Standard to 990 µL of dH2O, mix well. Add 0, 2, 4, 6, 8, 10 µL into a series of standards wells on a 96 well plate. Adjust volume to 50 µL/well with Assay Buffer to generate 0, 2, 4, 6, 8, 10 nM/well of G6P Standard.
3. Develop: Mix enough reaction mix for the number of samples and standards to be performed: For each well, prepare a total 50 µL Reaction Mix containing: Reaction Mix Background G6P Assay Buffer 46 µL 48 µL G6P Enzyme Mix 2 µL ---- G6P Substrate Mix 2 µL 2 µL Add 50 µL of the Reaction Mix to each well containing the G6P Standard and samples. Add 50 µL of the background mix into background control wells.
4. Incubate for 30 minutes at room temperature, protect from light.
5. Measure OD at 450 nm.
Ergebnisberechnung

Calculation: Correct background by subtracting the value of the 0 G6P blank from all sample readings. If background control reading is significant, subtract the background reading from sample reading. Plot the standard curve. Apply the corrected sample readings to the standard curve to get G6P amount in the sample wells. The G6P concentrations in the test samples: C = Ay/Sv (nM/µL, or μM/mL, or mM) Where: Ay is the amount of G6P (nmol) in your sample from the standard curve. Sv is the sample volume (µL) added to the sample well. Glucose-6-phosphate molecular weight: 260.14. Glucose-6-phoshate standard curve generated using this kit protocol
