3772227-3	1986	We found that these enzymes were stable for catalytic activity and immunologic (mass) measurements up to 24 hours at ambient temperatures and for at least 28 days at 4 degrees, -20 degrees, and -80 degrees C. The addition of exogenous pyridoxal phosphate (0.1 mmol/L) to serum improved stability of AST storage at ambient temperature (22 degrees C) from 1 day to 7 days.
