BrM lipoproteins, in situ and isolated. A–B, D, F–G. QFDE images of normal BrM (Huang, 2007). E. Negative stain electron microscopy (Li et al., 2005a). A. Core and surface of tightly packed lipoproteins. B. Fused lipoproteins. C. Interpretive schematic based on panel B. D. Small granular particles associated with lipoproteins. E. Isolated particles are large, spherical, and electron-lucent. F,G. Lipoproteins in untreated tissue (F) and in tissue treated with chloroform-methanol to remove lipid (G). Only some surface components, presumably apolipoproteins, remain after extraction. Bar in E = 50 nm, applies to panels A–E. Bar in G = 200 nm, applies to panels F and G.
