the bile-to-plasma ( b/p ) ratio of these different markers , including microperoxidase ( b/p ratio = 0.06 ; mol wt = 1,879 ) , insulin ( b/p ratio = 0.09 , mol wt = 5,000 ) , horseradish peroxidase ( b/p ratio = 0.04 , mol wt = 40,000 ) , and dextran ( b/p ratio = 0.09 , mol wt = 70,000 ) , exhibited no clear ordering based on size alone , and when dextrans of two different sizes ( 40,000 and 70,000 mol wt ) were studied simultaneously , the relative amounts of the two dextran species in bile were the same as in perfusate .
