Description

Localization of cross-linking proteins in fibroblast cytoskeleton. Fluorescence microscopy and corresponding intensity profiles human 356 fibroblast lamellipodia double stained with TRITC-phalloidin (red) and ABP-280 (green). The protein/actin ratio at the leading edge of the lamellipodium is medium for ABP-280. Immuno-EM of the cell edge (CIL 34926) or interior (CIL 34929) of cytochalasin D treated human 356 fibroblasts stained with ABP-280 primary antibody and 10-nm gold-conjugated secondary antibody reveals ABP-280 at filament crossovers in the cell interior. Image corresponds to Figure 5b and b' from J Cell Biol. 1999 May 31;145(5):1009-26.

Technical Details

Procedures for detergent extraction, immunostaining, S1 decoration, light, and EM were described previously (Svitkina et al., 1995, 1996, 1997;Verkhovsky et al., 1995; Svitkina and Borisy, 1998).
