glomerular permeability to horseradish peroxidase , a protein slightly smaller than rat albumin but similar in shape , was studied in wistar-furth rats by using a purified neutral isozyme ( hrp ; molecular radius , a ( e ) = 29.8 a ) as well as an anionic succinyl-derivative ( shrp a ( e ) = 31.8 a ) and a cationized enzyme ( chrp , a ( e ) = 30 a ) .
