[ noun ] the quality of being specific rather than general
: "add a desirable note of specificity to the discussion" "the specificity of the symptoms of the disease"

There is no conclusive evidence yet that either of the proteases has been prepared in highly purified form nor is their specificity known .(A. N. Nagaraj and L. M. Black, "Localization of...)
Two absorptions of * * f with ethyl_acetate or two absorptions of * * f ( which had been passed_through Dowex-2-chloride ) , NS and * * f with crown_gall tissue powder , or mouse liver powder did not further improve the specificity of staining .
In the latter cases an additional treatment of the DEAE cellulose treated * * f with 50 mg of sweet_clover stem tissue powder further improved the specificity .
The specificity of staining in WTV tumors with * * f and * * f but not with NS and * * f or with antiserum to potato_yellow-dwarf_virus and * * f , and the absence of such staining in crown_gall tumor tissue from sweet-clover , indicate that an antigen of WTV was being stained .
The specificity of staining with * * f was established as_follows : * * f specifically stained tumor sections but not sections of healthy sweet_clover stems or of crown_gall tumor tissue from sweet_clover .
[ noun ] the quality of being specific to a particular organism
: "host specificity of a parasite"

In attempting to improve specificity of staining , the fluorescein labeled antisera used in both direct and indirect methods were treated in one of several ways : ( 1 ) They were passed_through Dowex-2-chloride twice and treated with acetone insoluble powders ( Coons , 1958 ) prepared from mouse liver or from healthy sweet_clover stems or crown_gall tissue produced by Agrobacterium_tumefaciens ( E._F._Smith + Townsend ) Conn , on sweet_clover stems .
