anionic ferritin ( pi 4.5 ) did not bind to the capillary wall , ferritin ( pi 7.4 ) bound discontinuously only to the laminae rarae of the basement membrane , but cationized ferritin ( cf , pi 8.3 ) bound as a thick continuous layer to the cell plasmalemma and bound to the anionic matrix in the fenestral spaces .
