## Add 700 uL Glucose Buffer Solution with Color Reagent to a plastic cuvette. (for microplate add 100ul)
## Add 100 uL of Glucose buffer solution to each well, including wells for standard curve and blank
## Add 1-5 uL glucose standard (500mg/dL) for standard curve (for microplate add 1-5 ul of glucose standard 200mg/dL diluted 1:5)
## Add 1-5 ul of glucose standard 200mg/dL diluted 1:5
## Add 10 uL digested glycogen (for mice fasted more than 6 hours. for fed/short fast need less)
## Add 10 uL digested glycogen for fasted samples, and use a 10X dilution for refed tissues (using either 5 or 2ul from the diluted sample)
