Proteins of metaphase chromosomes and interphase chromatin.
Metaphase chromosomal and interphase chromatin proteins from cells of two species have been compared by polyacrylamide gel electrophoresis. Consistent, common changes in the quantitative distribution of the nonhistone chromosomal proteins are observed in both species. Proteins of ca. 65,000 and 68,000 MW are enriched in interphase chromatin while proteins of ca. 50,000 and 200,000 are more prom...
متن کاملUltra-violet Light and Vaccine Virus
Rabbit skin treated for a few minutes with ultra-violet light and then inoculated at once with vaccine virus is less susceptible to the action of the virus than is untreated skin. If 24, 48, or 72 hours elapse between the time of irradiation and inoculation, the treated skin appears to be more susceptible than is untreated skin. Skin repeatedly exposed to ultra-violet light is less susceptible ...
متن کاملThe Abiotic Action of Ultra-violet Light
Typhoid bacilli are about one two-hundredth as sensitive to ultraviolet light of wave-lengths 2100 to 2800 Angström units as is the photographic plate. This sensitivity then falls off, decreasing rapidly to almost zero sensitivity at about 2970, the beginning of the sun's spectrum.
متن کاملAn Ultra-violet Light Monitor for Spear3
A synchrotron light monitor is an essential tool for operating a storage ring. For SPEAR3, the upgrade of the SPEAR storage ring, the light monitor was designed not only for monitoring the beam presence but also to measure beam parameters. To minimize diffraction effects, UV light around 200 nm is used to image the electron source rather than visible light. At 200 nm, the rms diffraction spot i...
متن کاملMetaphase and interphase fluorescence in situ hybridization mapping of the rice genome with bacterial artificial chromosomes.
Fluorescence in situ hybridization (FISH) is a powerful tool for physical mapping in human and other mammalian species. However, application of the FISH technique has been limited in plant species, especially for mapping single- or low-copy DNA sequences, due to inconsistent signal production in plant chromosome preparations. Here we demonstrate that bacterial artificial chromosome (BAC) clones...
