Immunoglobulin Synthesis in Bullfrog Larvae

The Journal of Immunology, 1973
Abstract The antibody-synthesizing capacity of tadpoles (Rana catesbeiana) has been studied with sheep erythrocytes as antigen. Tadpoles can mount an immune response similar to that seen in higher vertebrates except for a slower kinetic profile. They could not, however, be stimulated to elicit a true anamnestic response. The antibody had

Cytoplasmic cylinders in bullfrog oocytes

Journal of Ultrastructure Research, 1968
Electron microscopic studies of developing bullfrog tadpole oocytes have demonstrated cylindrical structures, 150 m μ in cross-sectional diameter and with a linearly continuous central core 35 m μ in diameter, present singly and in tangled or parallel clusters within the cytoplasm.

Heteropore populations of bullfrog alveolar epithelium

Journal of Applied Physiology, 1983
Diffusional fluxes of a large number of hydrophilic solutes and water across bullfrog (Rana catesbeiana) alveolar epithelium were measured in the Ussing-type flux chamber. Lungs were isolated from double-pithed animals and studied as flat sheets. Radioactive solutes and water were added to the upstream reservoir, and the rate of change of downstream ...

Bullfrog plasma cysteine proteinase inhibitor (CPI)

Immunopharmacology, 1996
Papain is inhibited by bullfrog plasma. CPI was isolated from bullfrog plasma by two step column chromatography; Cm-papain agarose column chromatography followed by FPLC Mono Q column chromatography with addition of benzamidine. Isolated CPI gave a single band on SDS-PAGE under reducing condition, and the molecular weight of reduced CPI was estimated ...

Homologous radioimmunoassay for bullfrog growth hormone

General and Comparative Endocrinology, 1991
Antiserum against bullfrog growth hormone (fGH) was produced by immunizing rabbits with the highly purified fGH obtained from adenohypophyses of adult bullfrogs. Histological studies on bullfrog adenohypophyses revealed that the cells that immunologically reacted with the antiserum against fGH corresponded to the ones positively stained with the ...

Sexual Dimorphism in Bullfrogs

Ecology, 1981
Data on body size, age/size at sexual maturity, and adult survival were obtained between 1975 and 1978 for a population of bullfrogs, Rana catesbeiana, at the E. S. George Reserve of the University of Michigan. Both males and females continued to grow when adults; older individuals were often 50% larger than newly matured individuals.
