distribution of myosin isoenzymes among skeletal muscle fiber types.using an immunocytochemical approach, we have demonstrated a preferential distribution of myosin isoenzymes with respect to the pattern of fiber types in skeletal muscles of the rat. in an earlier study, we had shown that fluorescein-labeled antibody against "white" myosin from the chicken pectoralis stained all the white, intermediate and about half the red fibers of the rat diaphragm, a fast-twitch muscle (gauthier and lowey, 1977). we have now extended this study to include antibodies prepare ...197990047
comparative serology of two clinical isolates of bacteroides fragilis and bacteroides thetaiotaomicron.antiserum prepared in rabbits against bacteroides fragilis showed numerous bands when reacted with b. fragilis antigen in ouchterlony plates. this antiserum also reacted with bacteroides thetaiotaomicron and showed one band of apparent identity with b. fragilis. the band of identity common for both organisms was lost if the antigen was heated at 80 degrees c for 30 min. antisera prepared against b. thetaiotaomicron did not react with b. fragilis.197990054
the histochemical distribution of protein bound sulfhydryl groups in human epidermis by the new staining method.recently, we synthesized a new fluorescent thiol reagent, n-(7-dimethylamino-4-methylcoumarinyl)-maleimide (dacm) which is nonfluorescent by itself but will react readily with -sh groups to form highly fluorescent addition products. by the use of this reagent, we studied the localization and concentration of -sh groups and s--s linkages in the human epidermis. the distribution of -sh groups in living layers was abundant in cytoplasm but not in nuclei. the fluorescence was concentrated on the cel ...197990070
the use of avidin-biotin interaction in immunoenzymatic techniques.biotin was covalently attached to antibodies, antigens and enzymes, and the effects of this labeling on the antigen and antibody binding capacity and on enzymatic activity were tested. based on avidin-biotin interaction, the labeled proteins were used in quantitative enzyme-immunoassay and enzyme-immunohistochemical staining procedures. two procedures were developed. in the first procedure, named the bridged avidin-biotin (brab) technique four steps were used sequentially in order to quantify or ...197990074
