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.

Hydrogen peroxide, serum biotinylated immunoglobulins, and avidin-biotin complexes were used according to the manufacturer's instructions; after induction of the color reaction with freshly made diaminobenzidine solution (Dakopatts, Glostrup, Denmark), slides were counterstained with hematoxylin.
Following several washes with PBS, the slides were exposed to goat anti-rabbit IgG, conjugated with fluorescein isothiocyanate (FITC, 1:200; BOSTER, China) or diaminobenzidine (DAB, 1:200; BOSTER, China) for 60 min at room temperature, and were then washed with PBS.
The immunoreactive protein bands were visualized using peroxidase substrate named 3, 3'- diaminobenzidine (DAB, Sigma, USA).
Diaminobenzidine (Lab Vision, TL-012-HDN with anti mouse IgG (H and U, anti rabbit IgG (H and L) yielded a characteristic brown end-product whereas fast red chromogen (DAKO, K 0597 with anti mouse IgG (H and U, anti rabbit IgG (H and L) yielded a red end-product.
1 g diaminobenzidine (DAB) (3,3',4,4'--tetraminobiphenyl, Sigma, St Louis, USA) in PBS (200 ml), plus 40 [micro]l of hydrogen peroxide.
Diaminobenzidine tetrahydrochloride was used as a chromogen to localise the peroxidase.
Prediluted immunohistochemical reagents [endogenous peroxidase block, normal serum block, HRP-streptavidin and diaminobenzidine (DAB)] were from an ImmunoCruz Staining System kit (Santa Cruz Biotechnology).
