Cross-reactivity, in a general sense, is the reactivity of an observed agent which initiates reactions outside the main reaction expected. This has implications for any kind of test or assay , including diagnostic tests in medicine, and can be a cause of false positives .
In organic chemistry, a cross-coupling reaction is a reaction where two different fragments are joined. Cross-couplings are a subset of the more general coupling reactions. Often cross-coupling reactions require metal catalysts. One important reaction type is this:
The Suzuki reaction or Suzuki coupling is an organic reaction that uses a palladium complex catalyst to cross-couple a boronic acid to an organohalide. [1] [2] [3] It was first published in 1979 by Akira Suzuki, and he shared the 2010 Nobel Prize in Chemistry with Richard F. Heck and Ei-ichi Negishi for their contribution to the discovery and development of noble metal catalysis in organic ...
Cross-presentation is the ability of certain professional antigen-presenting cells (mostly dendritic cells) to take up, process and present extracellular antigens ...
Cross-reactivity of the self epitope (α-subunit of the receptor) with antibodies produced against HSV suggests that the virus is associated with the initiation of myasthenia gravis. Not only does HSV cause immunologic cross-reactivity, but the gpD peptide also competitively inhibits the binding of antibody made against the α-subunit to its ...
Houseplants. Indoor plants can still release pollen, sap, or spores, and can also collect mold and dust. Symptoms of a plant allergy may include runny nose; itchy eyes, throat, and/or ears; skin ...
In one important reaction type, a main group organometallic compound of the type R-M (where R = organic group, M = main group centre metal atom) reacts with an organic halide of the type R'-X with formation of a new carbon-carbon bond in the product R-R'. The most common type of coupling reaction is the cross coupling reaction. [1] [2] [3]
At the ripe old age of 30, Heather Locklear thought she was too old to be on Melrose Place. “I was, like, 30. Or almost 30 or something like that,” Locklear, 63, continued. “And you guys ...
