Protein AA has identical size in all recipient mice. SDS-PAGE of extracts from murine splenic sections followed by western blot with an anti-mouse AA antiserum. 1–3 show protein AA induced with AL fibrils, 4–6 with common AA amyloid fibrils and 7–9 with vascular AA amyloid fibrils. The amount of amyloid varied and there was no amyloid left in materials from mouse No. 5 and 7.
