            PREPARATION OF REAGENT SOLUTIONS/SUSPENSIONS:
            1. Dilute the contents of bottle 1 (lichenase) to 20.0 mL with
            20 mM sodium phosphate buffer (pH 6.5). Divide into
            appropriay sized aliquots and store in polypropylene tubes at
            -20°C between use and keep cool during use if possible.
            Stable for > 2 years at -20°C.
            2
            2. Dilute the entire contents of bottle 2 (b-glucosidase) to
            20.0 mL with 50 mM sodium acetate buffer (pH 4.0). Divide
            into appropriay sized aliquots and store in polypropylene
            tubes at -20°C between use and keep cool during use if
            possible. Stable for > 2 years at -20°C.
            3. Dilute the contents of bottle 3 (GOPOD Reagent Buffer) to
            1 L with distilled water. Use immediay.
            NOTE: It is imperative that the lichenase is not crosscontaminated
            with b-glucosidase.
            4. Dissolve the contents of bottle 4 in 20 mL of solution 3
            and quantitatively transfer this to the bottle containing the
            remainder of solution 3. Cover this bottle with aluminium
            NOTE:
            1. If the concentrated buffer is stored at -20°C, it will form salt
            crystals that must be compley dissolved when this buffer is
            diluted to 1 L with distilled water.
            2. This buffer contains 0.4 % (w/v) sodium azide. This is a
            poisonous chemical and should be treated accordingly.
            foil to protect the enclosed reagent from light. This is
            Glucose Determination Reagent (GOPOD Reagent).
            Stable for ~ 3 months at 2-5°C or > 12 months at -20°C.
            If this reagent is to be stored in the frozen state, preferably it
            should be divide into aliquots that should be freeze/thawed
            only once during use.
            When the reagent is freshly prepared it may be light yellow
            or light pink in colour. It will develop a stronger pink
            colour over 2-3 months at 4°C. The absorbance of this
            solution should be less than 0.05 when read against distilled
            water.
            BUFFERS (NOT SUPPLIED):
            1. Sodium phosphate buffer (20 mM, pH 6.5)
            Dissolve 3.12 g of sodium dihydrogen orthophosphate dihydrate
            (NaH2PO4.2H2O) in 900 mL of distilled water and adjust the
            pH to 6.5 by the addition of 100 mM sodium hydroxide (4 g/L)
            [approx. 50 mL is required]. Adjust the volume to 1 L. Add 0.2 g
            of sodium azide. Stable for 2 months at 4°C.
            2. Sodium acetate buffer (50 mM, pH 4.0)
            Add 2.9 mL of glacial acetic acid to 900 mL of distilled water.
            Adjust to pH 4.0 by the addition of 1 M sodium hydroxide
            solution. Adjust the volume to 1 L. Add 0.2 g sodium azide.
            Stable for 2 months at 4°C.
            3. Sodium acetate buffer (200 mM, pH 4.0)
            Add 11.6 mL of glacial acetic acid to 900 mL of distilled water.
            Adjust to pH 4.0 by the addition of 1 M sodium hydroxide
            solution. Adjust the volume to 1 L. Add 0.2 g sodium azide.
            Stable for 2 months at 4°C.

            standards of 50 μg and/or 100 μg are included, in duplicate.
            The reagent blank comprises 0.1 mL distilled water + 0.1 mL
            sodium acetate buffer + 3.0 mL of GOPOD Reagent
            The glucose standards comprises 0.1 mL sodium acetate
            buffer + 0.1 mL D-glucose standard (50 μg/0.1 mL or 100 μg/0.1
            mL) + 3.0 mL GOPOD Reagent
            2. With each set of determinations at least one standard barley
            flour is also included.
            3. With each new batch of GOPOD Reagent the time for
            maximum colour formation with 100 μg of D-glucose standard
            should be checked. This is usually approx. 15 min.
            4. It is imperative that the lichenase enzyme preparation
            is not cross-contaminated with the b-glucosidase
            preparation (the reverse is not a problem).
