Ovalbumin (abbreviated OVA [1]) is the main protein found in egg white, making up approximately 55% of the total protein. [2] Ovalbumin displays sequence and three-dimensional homology to the serpin superfamily, but unlike most serpins it is not a serine protease inhibitor. [3]
The process of somatic cell nuclear transfer involves two different cells. The first being a female gamete, known as the ovum (egg/oocyte). In human SCNT experiments, these eggs are obtained through consenting donors, utilizing ovarian stimulation. The second being a somatic cell, referring to the cells of the human body.
Gilbert cloud chamber, assembled An alternative view of kit contents. The lab contained a cloud chamber allowing the viewer to watch alpha particles traveling at 12,000 miles per second (19,000,000 m/s), a spinthariscope showing the results of radioactive disintegration on a fluorescent screen, and an electroscope measuring the radioactivity of different substances in the set.

"Egg of Columbus" demonstration at the 1893 Columbian Exposition. Tesla's Egg of Columbus was a device exhibited in the Westinghouse Electric display at the 1893 Chicago World's Columbian Exposition to explain the rotating magnetic field that drove the new alternating current induction motors designed by inventor Nikola Tesla by using that magnetic field to spin a copper egg on end.
Xenopus egg extract is a lysate that is prepared by crushing the eggs of the African clawed frog Xenopus laevis. It offers a powerful cell-free (or in vitro ) system for studying various cell biological processes, including cell cycle progression, nuclear transport , DNA replication and chromosome segregation .
They suit to diagnose the general state of the blood coagulation system and the intensity of pathologies, and to simultaneously record all attendant influences. Global methods play the key role at the first stage of diagnostics: they provide an integral picture of alterations within the coagulation system and allow predicting a tendency to ...
The data are sent to a server in Princeton, creating a database of synchronized parallel sequences of random numbers. The GCP is run as a replication experiment, essentially combining the results of many distinct tests of the hypothesis. The hypothesis is tested by calculating the extent of data fluctuations at the time of events.
