- Alpha complementation is a method for bacterial screening that have been transformed with a plasmid vector, carrying the N-terminal coding sequence for β-galactosidase of the lac operon. The lac Z gene is required for galactosidase metabolism.

Maternal Serum Alpha-Fetoprotein Screening (MSAFP) Also Known as Alpha-Fetoprotein Test (AFP). MSAFP is a screening test that examines the level of alpha-fetoprotein in the mother’s blood during pregnancy. This is not a diagnostic test. It is often part of the triple screen test that assesses whether further diagnostic testing may be needed.

- Alpha amanitin is a molecule made from the “death cap” mushroom and is a known potent inhibitor RNA polymerase. One single mushroom could very easily lead to a fast death in 10 days. The mechanism of action is that alpha amanitin inhibits RNA polymerase at both the initiation and elongation states of transcription.

Elevated alpha-fetoprotein Elevated alpha-fetoprotein. Elevated alpha-fetoprotein refers to a state where alpha-fetoprotein levels are outside of the reference range. There are two categories of AFP tests: tests performed on serum (blood plasma), and tests performed on amniotic fluid. Tests performed on serum are further categorized by the reason for performing the test: maternal serum, adult tumor marker, and pediatric tumor marker.

What is Alpha Thalassemia? What is Alpha Thalassemia? Alpha thalassemia is a blood disorder that affects hemoglobin, a major component of red blood cells that carries oxygen in the body. Hemoglobin is a protein complex made up of two different chains. There are many forms of hemoglobin, but the primary type is made up of alpha chains and beta chains.

Addition Reaction The addition of hydrogen on double bond of alkene is known as hydrogenation of alkene which forms saturated hydrocarbons, alkanes. Hydrogenation of alkene is a heterogeneous catalytic reaction takes place on the surface of metal catalysts like palladium, platinum or nickel catalyst.

Alpha-1 antitrypsin deficiency Alpha-1 antitrypsin deficiency is an inherited disorder that may cause lung disease and liver disease. The signs and symptoms of the condition and the age at which they appear vary among individuals.bout 10 percent of infants with alpha-1 antitrypsin deficiency develop liver disease, which often causes yellowing of the skin and whites of the eyes (jaundice). Approximately 15 percent of adults with alpha-1 antitrypsin deficiency develop liver damage (cirrhosis) due to the formation of scar tissue in the liver.

complement complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed components of complement and are designated by the symbols C1 through C9. C1 is a calcium dependent complex of three distinct proteins C1q, C1r and C1s.The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names.Fragments resulting from proteolytic cleavage of complement proteins are designated with lower case letter suffixes, for example, C3a.omplement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins or chemotactic factors.

- Alpha-fetoprotein is a protein that in humans is encoded by the AFP gene. The AFP gene is located on the q arm of chromosome 4. AFP is a major plasma protein produced by the yolk sac and the liver during fetal development. It is thought to be the fetal form of serum albumin. AFP binds to copper, nickel, fatty acids and bilirubin and is found in monomeric, dimeric and trimeric forms.

Alpha-1 Antitrypsin Deficiency Alpha-1 antitrypsin deficiency (AAT deficiency) is an inherited condition that raises your risk for lung and liver disease. Alpha-1 antitrypsin (AAT) is a protein that protects the lungs. The liver makes it. If the AAT proteins aren't the right shape, they get stuck in the liver cells and can't reach the lungs.

Alpha 1 Antitrypsin Deficiency Alpha-1 antitrypsin deficiency (Alpha-1) is a hereditary genetic disorder which may lead to the development of lung and/or liver disease. It is the most common genetic cause of liver disease in children. Adults can also be affected by Alpha-1 and may develop lung conditions such as emphysema as well as liver problems.

- Aminotransfer reaction between an amino acid and an alpha-keto acid. Transamination (or aminotransfer) is a chemical reaction that replaces an amine functional group with another amine. In many applications, an amino acid is the substrate.The other substrate is a keto acid, which contains a keto (=O) group.In transamination, the NH 2 group on one molecule is exchanged with the =O group on the other. The original amino acid converts to a keto acid, and the keto acid converts to an amino acid.his process is an important step in the synthesis of some non-essential amino acids (amino acids that can be synthesized de novo by the organism). The chirality of an amino acid is determined during transamination.

- Guards are t … ypically assigned to people of importance, and so guarding a place of burial demonstrates how important the deceased is. The Honor Guard consists of soldiers because the Unknown is also a soldier, and because guard duty has traditionally been done by the military. The Tomb of The Unknown Soldier came to be after WWI when great numbers of men were killed and it was not always possible to identify and properly bury them all.
