Wrote initial protocol
 
added glucose quantification protocol
Line 6: Line 6:
* 50 mM Sodium Acetate, pH 4.8
* 50 mM Sodium Acetate, pH 4.8
* Amyloglucosidease
* Amyloglucosidease
* Glucose quantification kit (Wako Autokit Glucose Buffer Solution cat # 439-9091)
* Glucose standard solution (500 mg/dL; Wako)

Line 17: Line 19:
# Resuspend pellet in 200 uL of 50 mM Sodium Acetate, pH 4.8
# Resuspend pellet in 200 uL of 50 mM Sodium Acetate, pH 4.8
# Add 0.3 mg/mL amyloglucosidase and place at 37C for 3h
# Add 0.3 mg/mL amyloglucosidase and place at 37C for 3h
# Quantify glucose
# Quantify glucose using kit:
## Add 1-5 uL glucose standard for standard curve
## Add 10 uL digested glycogen
## Mix and incubate at 37C for 5 min
## Measure absorbance at 505 nm
## Calculate glycogen levels as umoles glucose released per g tissue (should be ~10)
