in addition , the isoelectric point of bovine albumin bound to [ 125i ] l-t3 ( 5.1 ) was higher than that of bovine albumin bound to [ 125i ] d-t3 ( 5.0 ) , as determined by isoelectric focusing , which indicates that the surface of the bovine albumin molecule is slightly more positive when the protein binds l-t3 as opposed to d-t3 .
