Silicon readily bonds with oxygen and is rarely found in nature in its pure form. You've likely seen silicon as silicon dioxide or silica, better known as quartz, which is the most common component of sand.Silica also comes in other mineral forms, such as flint, jasper and opal.ilicon is the 14th element on the periodic table. It's a metalloid, meaning it has properties of both metals and nonmetals, and is the second most abundant element in the Earth's crust, after oxygen.
Heterophile antibodies are human antibodies with the ability to bind to animal immunoglobulins, thereby possibly interfering with the interaction between animal-derived antibodies and the antigen [hCG in our discussion], which are components of all immunoassays.
There are several kinds of antiphospholipid antibodies. The three most widely measured are lupus anticoagulant, anticardiolipin antibody, and anti-Î² 2 glycoprotein I. These antibodies react with proteins in the blood that are bound to phospholipid, a type of fat molecule that is part of the normal cell membrane.utoantibodies are antibodies that are directed against oneâs self. Antiphospholipid antibodies interfere with the normal function of blood vessels, causing narrowing and irregularity of the vessel (vasculopathy), and by causing blood clots in the vessel (thrombosis).
