fluor·es·cent an·ti·bod·y

an immunoglobulin (antibody) to which a fluorescent dye has been attached.

fluorescent antibody

Abbreviation: FA
An antibody that has been stained or marked by a fluorescent material. The fluorescent antibody technique permits rapid diagnosis of various infections.

Two serologic methods can detect antibodies: (1) the indirect fluorescent antibody assay, which has a sensitivity of 88% and a specificity of 97%, (8) and (2) the enzyme immunoassay, which has become less popular in light of the high sensitivity and specificity of the indirect fluorescent antibody assay.
Stranger still, in relation to another work that used dyed fluorescent antibody molecules to examine the cellular response to sudden environmental changes (in temperature, salinity, pH, and so on), the press release invoked not cellular biology but 9/11 as the determinant referent, explaining that "stress" has lately become a hot research topic, perversely reading cellular research as a cultural pathology.
Cases reported by culture, direct fluorescent antibody, and serology declined significantly during this time, while cases diagnosed by urine antigen testing increased.
Although the Western blot is the most common confirmatory test, others are sometime used, including the indirect fluorescent antibody assay (IFA) and the radioimmunoprecipitation assay (RIPA).
Using a different fluorescent antibody to light up the intact protein in each altered cell, the researchers revealed complex internal structures made of either MreB or Mbl.
