Dab

 

(Limanda limanda), a fish of the family Pleuronectidae. The dab’s lateral line has a bend above the pectoral fin. The fish is usually 20–30 cm long (sometimes up to 40 cm) and weighs 150–300 g (sometimes up to 700 g). It is distributed in the seas that wash the western and northern coasts of Europe (from the Bay of Biscay to the White Sea). It keeps to the coastal zone at depths not exceeding 50–70 m. Spawning takes place from May through August at a depth of 25–50 m; the fecundity is 80,000–140,000 eggs. The eggs float in the depths of the water; the larvae are symmetrical and live on the bottom even before they acquire their asymmetrical shape. The dab feeds on invertebrates, less frequently, on small fish. The fish has commercial importance in the USSR; it is caught mainly with trawling nets. ?≫i_4i

DAB

(Digital Audio Broadcasting) The digital radio standard in most countries except for the U.S., which uses iBiquity's HD Radio, and Japan, which uses Terrestrial Integrated Services Digital Broadcasting (ISDB-T). Developed by the Eureka 147 Project in Europe, DAB uses frequencies from 175 to 239 MHz and 1.45 to 1.49 GHz. DAB+, which is backward compatible with DAB, is based on the aacPlus Version 2 digital audio standard (see aacPlus). For more information, visit the World DAB Forum at www.worlddab.org. See HD Radio and mobile TV.

The Leica polymer and postpolymer were each incubated for 30 minutes, followed by 10 minutes in diaminobenzidine, and a light hematoxylin counterstain.
Specimens were then rinsed six to eight times over 10 h in PBS + Triton-X 100, followed by incubation for 30 min in diaminobenzidine (solution provided in kit marketed by DAKO Diagnostics, Mississauga, ON, Canada) diluted into PBS.
The reaction was visualized by incubating the sections in a solution of 0.1 % 3,30 diaminobenzidine (DAB) and 0.02 % [H.sub.2][O.sub.2] for 7 min (DAB substrate kit; Invitrogen).
Detection of the primary antibody or mouse IgG11j was performed using EnVision FLEX+ Polymer reagents (horseradish peroxidase polymer, diaminobenzidine chromogen, and diaminobenzidine enhancer), washing with EnVision FLEX+ wash buffer between the incubation steps.

Mouse monoclonal antibody clone 124 against bcl-2, rabbit anti-mouse IgG alkaline phosphatase conjugate, biotinylated rabbit anti-mouse antibody, the avidin-biotin-peroxidase complex kit, and diaminobenzidine were purchased from Dako.
The reaction was visualized by incubating the sections for 7 min in a 0.1 % 3,3 diaminobenzidine and 0.02 % hydrogen peroxide solution (DAB substrate kit, Invitrogen, Carlsbad CA).
Each strip was incubated with a 1:100 dilution of individual serum specimens in 0.3% Tween-PBS, peroxidase-conjugated goat antibody (Bio Source International Inc., Camarillo, CA, USA) diluted 1:4,000 in 0.05% Tween-PBS, and blots were developed by diaminobenzidine substrate solution containing [H.sub.2][O.sub.2].
