(nū'trăl-i-zā'shŭn),
1. The change in reaction of a solution from acid or alkaline to neutral by the addition of just a sufficient amount of an alkaline or of an acid substance, respectively.
2. The rendering ineffective of any action, process, or potential.

neutralization

Etymology: L, neutralis + Gk, izein, to cause
the interaction between an acid and a base that produces a solution that is neither acidic nor basic. The usual products of neutralization are a salt and water. neutralize, v.

neutralization

1. A technique for determining the power of an ophthalmic lens. It is accomplished by placing a lens of known power and opposite sign in contact with the unknown lens and moved back and forth in a plane perpendicular to the line of sight until the observation of movement (against or with) of the distant image seen through the lenses disappear. The unknown lens will have the opposite power to that which neutralizes this apparent movement. 2. A method of breaking down hydrogen peroxide from a contact lens (mostly soft) following contact lens disinfection to avoid possible irritation to ocular tissues. This can be achieved by rinsing and dilution with saline, by using a solution with an enzyme catalase or a platinum disc incorporated into the lens case, or with a chemical agent such as sodium pyruvate or sodium thiosulfate. See disinfection; focimeter.

neutralization

the state of having been converted to neutrality from acid or base. Used also in microbiology to indicate neutralization of a toxin or of infectivity.

neutralization tests
tests based on the ability of an antibody to neutralize the biological activity of an antigen. These may utilize antitoxins and toxins or immune serum and viruses or bacteria. The tests are often quantitative whereby antibody (serum) is serially diluted; the reciprocal of the highest dilution of serum neutralizing a standard amount of toxin or virus or bacteria is the neutralizing antibody titer of that serum.

Although HI titers are typically expressed as the serum starting dilution before any addition of virus, calculation of starting dilutions for neutralization varies among laboratories.
One problem was that limited serum quantities precluded our ability to test for neutralization and enhancement in primary cultures of human monocytes.
