Brooker's merocyanine (1-methyl-4-[(oxocyclohexadienylidene)ethylidene]-1,4-dihydropyridine, MOED) [1] is an organic dye belonging to the class of merocyanines. MOED is notable for its solvatochromic properties, meaning it changes color depending on the solvent in which it is dissolved.
Another solution for live-cell imaging is the dipping lens. These lenses are a subset of water-immersion lenses that do not require a cover slip and can be dipped directly into the aqueous environment of the sample. One of the main advantages of the dipping lens is that it has a long effective working distance. [29]
Principles of Biology is a college level biology electronic textbook published by Nature Publishing in 2011. The book is not a digitally reformatted version of a paper book. [ 1 ] The book, the first in a projected series, is Nature Publishing's first foray into textbook publishing.
Modelling biological systems is a significant task of systems biology and mathematical biology. [a] Computational systems biology [b] [1] aims to develop and use efficient algorithms, data structures, visualization and communication tools with the goal of computer modelling of biological systems.
Biological thermodynamics (Thermodynamics of biological systems) is a science that explains the nature and general laws of thermodynamic processes occurring in living organisms as nonequilibrium thermodynamic systems that convert the energy of the Sun and food into other types of energy.
Systems biology is the computational and mathematical analysis and modeling of complex biological systems.It is a biology-based interdisciplinary field of study that focuses on complex interactions within biological systems, using a holistic approach (holism instead of the more traditional reductionism) to biological research.
The solution is treated with a concentrated salt solution (saline) to make debris such as broken proteins, lipids, and RNA clump together. Centrifugation of the solution, which separates the clumped cellular debris from the DNA. DNA purification from detergents, proteins, salts, and reagents is used during the cell lysis step.
Second messengers are intracellular signaling molecules released by the cell in response to exposure to extracellular signaling molecules—the first messengers. (Intercellular signals, a non-local form of cell signaling , encompassing both first messengers and second messengers, are classified as autocrine , juxtacrine , paracrine , and ...
