both hormone variants have essentially the same binding characteristics : slow association ( equilibrium reached in 8-10h at 30 degrees c ) , poor reversibility ( 'tight binding ' ) , linear scatchard plot , same specificity as shown by lack of competition by bovine , porcine or equine growth hormones or human growth hormone- ( 32-46 ) - ( missing in the 20000-mr variant ) , - ( 1-134 ) - and - ( 141-191 ) -peptides .
