1. Diferenciação celular em Nostoc spp: efeito da intensidade luminosa e do padrão de sobreposição dos filamentos / Cellular differentiation in Nostoc spp: effects of light intensity and pattern of filaments superposition.
Em isolados do gênero Nostoc, a multiplicação das células vegetativas e a diferenciação de algumas células em heterócitos em intervalos regulares é a etapa do ciclo de vida em que ocorre a produção de biomassa. Em outra etapa do ciclo de vida, vários fatores do ambiente podem induzir a diferenciação de hormogônios, filamentos nos quais não oc

2. Lysosomes are associated with microtubules and not with intermediate filaments in cultured fibroblasts.
Double immunofluorescent labeling experiments for lysosomes and either microtubules or vimentin intermediate filaments in cultured well-spread fibroblasts show a remarkable degree of superposition of the lysosomes and the microtubules. Under two different sets of conditions where the microtubules and intermediate filaments are well segregated from one anothe

3. Association of microtubules and intermediate filaments in chicken gizzard cells as detected by double immunofluorescence.
By double indirect immunofluorescence, using guinea pig and rabbit antibodies to tubulin and to desmin, we have simultaneously labeled microtubules and intermediate filaments in cultured chicken embryo gizzard cells. At the resolution of the light microscope there was extensive but not complete superposition of the labeling patterns for the two filamentous s

4. Formation of two-dimensional complexes of F-actin and crosslinking proteins on lipid monolayers: demonstration of unipolar alpha-actinin-F-actin crosslinking.
A method is described for forming two-dimensional (2-D) paracrystalline complexes of F-actin and bundling/gelation proteins on positively charged lipid monolayers. These arrays facilitate detailed structural studies of protein interactions with F-actin by eliminating superposition effects present in 3-D bundles. Bundles of F-actin have been produced using th
