The activity of lactoperoxidase was measured by using 2.2-azino-bis(3-ethylbenzthiazoline-6 sulfonic acid) diammonium salt (ABTS) as a choromogenic substrate at pH 6.0.
      
Capacity for ligninolytic enzyme production was examined at 35 and 43C on agar media containing 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) and MnCl2.
      
They prove to be 7.0 for syringaldazine, 8.0 for pyrocatechol, and 4.0 for 2,2'-azine-bis-(3-ethylbenzothiazoline-6-sulfonate and 2,6-dimethoxyphenol.

The kinetics of interaction between organic nitrates (3,3-bis(nitroxymethyl)oxetane) and cysteine were evaluated by the rate of nitrite ion formation at various concentrations of reagents and pH.
      
The activities of natural reducing agents, including cysteine, glutathione, and NADH, in generating the nitrite ion from organic nitrates (3,3-bis(nitroxymethyl)oxetane) were compared.
      
Initiation and Inhibition of Free Radical Processes in H2O2-Metmyoglobin (Methemoglobin)-2,2"-Azino-bis-(3-Ethylbenzthiazoline-6
      
Rates of free radical initiation were determined at 20°C in 10 mM phosphate buffer (pH 7.4) in the systems metmyoglobin (methemoglobin)-H2O2 using 2,2"-azino-bis-(3-ethylbenzthiazoline-6-sulfonic acid) as the diammonium salt (ABTS).
      
The results were compared with those of brain type creatine kinase (CK-BB) and dithio-bis(succinimidyl propionate) cross-linked CK-MM.
      
The intensities of B1 and B2 bands detected in the absence of an inducer increased after 30 min protein incubation with phenobarbital (PB) or triphenyldioxane (TPD), but not with 1,4-bis[2-(3,5-dichloropyridyloxy)]benzene (TCPOPOB).
      
A feature of AOPTP is low pH value (3.0) at which the peroxidase shows its maximal activity toward 2,2"-azino-bis(3-ethylbenz-thiazoline-6-sulfonic acid) (ABTS).
      
The reactivation yield of recombinant tobacco enzyme was about 7% with the specific activity of 1100-1200 U/mg towards 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonate) (ABTS).

A new Mg(II) complex of MgL(NO3)2 (here L = N1,N8-bis(1-methyl-4-nitropyrrole-2-carbonyl)triethylenetetramine) has been synthesized and characterized.
      
Contrary to the adsorption of monoquaternary ammonium compound, cetyltrimethylammonium bromide, the adsorption of bis(quaternary ammonium) compounds, ethonium and decamethoxine, was found to be caused mainly by electrostatic interaction.
