we have identified the three-dimensional ultrastructure of actin gels that are formed in well-characterized cell extracts and mixtures of purified actin and the 120k actin-binding protein and compared these to the ultrastructure of the cytoplasmic matrix in regions of nonextracted dictyostelium amoebae that are rich in actin and 120k .
