Enzymes

a

ENZYMES Should be stored in a refrigerator at 4°C. This should ensure a shelf life of up to 12 months. They should be regarded as being 100% for the purposes of dilution, e.g. 1g/1ml in 100ml water gives a 1% solution. pH = optimum range. Temp = optimum range. Working conc. = recommended dilution. Source = Origin
