Mindblown: a blog about philosophy.

A highly purified form of agar. Used as a stationary phase (substrate) in some chromatography and electrophoretic methods.  

The transfer of an immune state from one animal to another by means of lymphocyte transfusions.  

The increase in immune response that is achieved by selectively removing certain immune system cells from (a patient’s) body, multiplying them in vitro outside the body to greatly increase number, then reinserting those (more numerous) immune system cells into the same body.  

Required by America’s Food and Drug Administration (FDA) for approval of new food ingredients. Uptake of a substance through the skin or a mucous membrane.  

A glycoprotein “chain” that protrudes from the surface membrane of certain cells, and causes cells (possessing “matching” adhesion molecules) to adhere to each other. For example, in 1952 Aaron Moscona observed that (harvesting enzyme-separated) chicken embryo cells did not remain separated, but instead coalesced again into an (embryo) aggregate. In 1955, Philip Townes and Johannes…

A ribonucleoside 5 ‘-monophosphate that is formed by hydrolysis of ATP or ADP. A hormone secreted by the parafocicular cells of the thyroid gland to regulate the level of blood calcium. Substance formed by condensation of adenosine and phosphoric acid. It is one of the hydrolytic products of nucleic acids and is present in muscle,…

A ribonucleoside 5 ‘-diphosphate serving as phosphate-group acceptor in the cell energy cycle. A compound (ester) composed of one molecule each of adenine and D-ribose and two molecules of phosphoric acid is formed as a result of the breakdown of adenosine triphosphate and is used in the resynthesis of adenine triphosphate, adenosine triphosphatase (ATPase). A…

Genes that interact but do not show dominance (in the case of alleles) or epistasis (if they are not alleles).  

Short-term infection of cells with DNA.  

The factor by which the concentration of a solute must be multiplied to give its true thermodynamic activity. A factor used in potentiometry to describe the activity of free ions in solution.
