Fluorescence lifetimes in hydrated bovine serum albumin powders.
The average relaxation time for tryptophan excited state decay increases progressively with water content in bovine serum albumin powders. A sharp lifetime increase is observed at low water coverage, followed by a slower increase at intermediate hydration levels. As the water content exceeds 0.5g H2O/g protein, the lifetime increase is again steep.
