Ibrahim Cissé (academic)
Ibrahim I. Cissé is an Nigerien-American biophysicist. He is currently director of the Max Planck Institute of Immunobiology and Epigenetics. Previously, Cissé was at the California Institute of Technology as Professor of Physics and the Massachusetts Institute of Technology as Professor of Physics and Biology. He has won several awards for his work, including in 2021 the MacArthur Fellowship. Cissé's research focuses on live cell super-resolution imaging and single molecule characterisation. Early life and education Cissé was born in Niamey, Niger. As a child he assumed that he would work in his father's law firm. He became interested in science through Hollywood films. In Niamey there were few opportunities to practise science as his school did not have a laboratory. He was keen to move to America to study, and completed high school two years early. He moved to the United States at the age of 17 to attend college. Cissé studied physics at the North Carolina Central Unive ...

Max Planck Institute Of Immunobiology And Epigenetics
The Max Planck Institute of Immunobiology and Epigenetics (German: ''Max-Planck-Institut für Immunbiologie und Epigenetik'') in Freiburg, Germany is an interdisciplinary research institute that conducts basic research in modern immunobiology, developmental biology and epigenetics. It was founded in 1961 as the Max Planck Institute of Immunobiology and is one of 86 institutions of the Max Planck Society. Originally named the Max Planck Institute of Immunobiology, it was renamed to its current name in 2010 as it widened its research thrusts to the study of epigenetics. The researchers of the institute study the development of the immune system and analyse the genes and molecules which are important for its function. They also seek to establish which factors control the maturation of immune cells and how chemical changes of the DNA influence the immune defense. The biologist Georges J. F. Köhler, a co-recipient of the 1984 Nobel Prize in Physiology or Medicine, was director of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caltech
The California Institute of Technology (branded as Caltech or CIT)The university itself only spells its short form as "Caltech"; the institution considers other spellings such a"Cal Tech" and "CalTech" incorrect. The institute is also occasionally referred to as "CIT", most notably in its alma mater, but this is uncommon. is a private university, private research university in Pasadena, California. Caltech is ranked among the best and most selective academic institutions in the world, and with an enrollment of approximately 2400 students (acceptance rate of only 5.7%), it is one of the world's most selective universities. The university is known for its strength in science and engineering, and is among a small group of Institute of Technology (United States), institutes of technology in the United States which is primarily devoted to the instruction of pure and applied sciences. The institution was founded as a preparatory and vocational school by Amos G. Throop in 1891 and began ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

RNA Polymerase II
RNA polymerase II (RNAP II and Pol II) is a multiprotein complex that transcribes DNA into precursors of messenger RNA (mRNA) and most small nuclear RNA (snRNA) and microRNA. It is one of the three RNAP enzymes found in the nucleus of eukaryotic cells. A 550 kDa complex of 12 subunits, RNAP II is the most studied type of RNA polymerase. A wide range of transcription factors are required for it to bind to upstream gene promoters and begin transcription. Discovery Early studies suggested a minimum of two RNAPs: one which synthesized rRNA in the nucleolus, and one which synthesized other RNA in the nucleoplasm, part of the nucleus but outside the nucleolus. In 1969, science experimentalists Robert Roeder and William Rutter definitively discovered an additional RNAP that was responsible for transcription of some kind of RNA in the nucleoplasm. The finding was obtained by the use of ion-exchange chromatography via DEAE coated Sephadex beads. The technique separated the enzymes ...

Photoactivated Localization Microscopy
Photo-activated localization microscopy (PALM or FPALM) and stochastic optical reconstruction microscopy (STORM) are widefield (as opposed to point scanning techniques such as laser scanning confocal microscopy) fluorescence microscopy imaging methods that allow obtaining images with a resolution beyond the diffraction limit. The methods were proposed in 2006 in the wake of a general emergence of optical super-resolution microscopy methods, and were featured as Methods of the Year for 2008 by the ''Nature Methods'' journal. The development of PALM as a targeted biophysical imaging method was largely prompted by the discovery of new species and the engineering of mutants of fluorescent proteins displaying a controllable photochromism, such as photo-activatible GFP. However, the concomitant development of STORM, sharing the same fundamental principle, originally made use of paired cyanine dyes. One molecule of the pair (called activator), when excited near its absorption maximum, ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
In Vitro
''In vitro'' (meaning in glass, or ''in the glass'') studies are performed with microorganisms, cells, or biological molecules outside their normal biological context. Colloquially called "test-tube experiments", these studies in biology and its subdisciplines are traditionally done in labware such as test tubes, flasks, Petri dishes, and microtiter plates. Studies conducted using components of an organism that have been isolated from their usual biological surroundings permit a more detailed or more convenient analysis than can be done with whole organisms; however, results obtained from ''in vitro'' experiments may not fully or accurately predict the effects on a whole organism. In contrast to ''in vitro'' experiments, ''in vivo'' studies are those conducted in living organisms, including humans, and whole plants. Definition ''In vitro'' ( la, in glass; often not italicized in English usage) studies are conducted using components of an organism that have been isolated fro ...
