Cytochrome P450-dependent monooxygenases, in spite of their wide distribution, can be simply divided into a few groups differing in the location of the electron transfer chain and their composition. The two main groups of cytochrome P450-dependent mo

Our previous chemical modification and cross-linking studies identified some positively charged amino acid residues of cytochrome P450scc that may be important for its interaction with adrenodoxin and for its functional activity. The present study wa

The conditions for heterologous expression of recombinant bovine adrenodoxin in E. coli have been optimized, thus reaching expression levels up to 12-14 micromoles per liter of culture medium. A highly efficient method for purification of this recomb

Optimization of the conditions for heterologous expression of recombinant cytochrome P450scc in E. coli provided an expression level of about 420 nmoles of cytochrome P450scc per liter of bacterial culture. A new procedure for purification of recombi

Clinical modification of cytochrome P450scc with fluoresceine isothiocyanate (FITC) results in selective incorporation of the fluorescent label into Lys338. According to affinity chromatography on immobilized adrenodoxin, fluorescently labeled cytoch

The possibilities of direct antigen detection in unlabelled systems based on immunoglobulin G Langmuir-Blodgett films as a sensitive surface have been studied. It was shown that an increase in the monolayer number in an immunoglobulin G Langmuir-Blod

Since immunoglobulins are used in a vast variety of immunoassays, the problem of obtaining antibodies with enhanced antigen-binding activity is of great importance. In order to discriminate between putative approaches to activating antibody modificat

The possibility of improving analytical parameters of the immunometric assay with the use of biotinylated antibodies and biotin-streptavidin complexes in comparison with the commonly known approach of direct antibody modification with 125I has been s
