title: Actin and actin-binding proteins in plasma membranes derived from Walker 256 ascites or solid tumour cells.
abstract: Plasma membranes from Walker 256 carcinoma cells grown ascitically or as a solid tumour were examined with respect to actin content, [3H]cytochalasin B-binding and the binding of 125I-labelled G-actin to membrane proteins separated by SDS-PAGE. Differences were observed both in cytochalasin B-binding to membrane actin and affinity of 125I-labelled G-actin for specific membrane proteins.
