Sigma Advanced Genetic Engineering (SAGE) Labs is a division within Sigma-Aldrich that specializes in genetic manipulation of in vivo systems for special research and development applications. It was formed in 2008 to investigate zinc finger nuclease technology and its application for disease research models.
Merck is a supplier to the life science industry. The Millipore Corporation was founded in 1954, and listed among the S&P 500 since the early 1990s, as an international biosciences company which makes micrometer pore-size filters and tests. In 2015, Merck acquired Sigma-Aldrich and merged it with Merck Millipore.
The life science business of Merck, formerly known as Merck Millipore, was created in July 2010 following the completed acquisition of the US company Millipore. It employs around 19,000 people in 66 countries and runs 65 manufacturing sites and uses the brands Sigma-Aldrich, Milli-Q and Millipore. [ 64 ]
Two pi bonds are the maximum that can exist between a given pair of atoms. Quadruple bonds are extremely rare and can be formed only between transition metal atoms, and consist of one sigma bond, two pi bonds and one delta bond. A pi bond is weaker than a sigma bond, but the combination of pi and sigma bond is stronger than either bond by itself.
Millipore may refer to: Millipore Corporation, a biosciences company acquired by Merck Group in 2010; MilliporeSigma, former name of Sigma-Aldrich; Merck Millipore, deprecated brand name used by Merck Group after Millipore acquisition
In chemistry, π-effects or π-interactions are a type of non-covalent interaction that involves π systems.Just like in an electrostatic interaction where a region of negative charge interacts with a positive charge, the electron-rich π system can interact with a metal (cationic or neutral), an anion, another molecule and even another π system.

Every week in the NFL season brings a host of new questions … and answers some old ones, too. Let’s run down what we learned in Week 7 … and what we’ll be wondering about in Week 8 and beyond.
(J/psi) meson / ˈ dʒ eɪ ˈ s aɪ ˈ m iː z ɒ n / is a subatomic particle, a flavor-neutral meson consisting of a charm quark and a charm antiquark. Mesons formed by a bound state of a charm quark and a charm anti-quark are generally known as "charmonium" or psions. [1] The J/ψ is the most common form of charmonium, due to its spin of 1 ...
