Rocket-linear immunoelectrophoresis enabled to estimate the alpha-fetoprotein content in blood serum of pregnant women. Sensitivity of the procedure constituted as low as 13-22 ng of the protein per I ml of blood serum. Concentration of the protein in blood serum depended on the period of pregnancy; middle values of normal content of alpha-fetoprotein in(More)
A test system for enzyme immunoassay of alpha-fetoprotein (AFP) was developed on the basis of the diagnostic agents manufactured by the N. F. Gamaleya Research Institute of Epidemiology and Microbiology. The effect of shielding antibody active centers in sensitization of planes with excessive concentrations of antibodies was detected. The test system was(More)
The purpose of the work is to develop testing and calibration technique of large phased antenna arrays using reference noise generator as a standard signal source. This technique is developed for calibration of the phased antenna array of the unique decameter wave radio telescope UTR-2, but they could be easy adapted for similar large arrays with analog and(More)
The review is dedicated to the 30th anniversary of the opening and studying of alpha-fetoprotein (AFP). New data about molecular properties, structure and functions as well as regulation of AFP synthesis are presented. Clinical significance and prospects of the further study of this oncofetal glycoprotein has been discussed.
The paper presents new information about the carbohydrate structures of 39-days chicken's fibronectin. It is found out that chicken fibronectin contains mainly biantennary N-glycans with a core fucose and fucosylated O-glycans. It is shown that N-glycans of chicken fibronectin are poorly sialated, since this protein exhibits affinity for the PNA and weak(More)
Activity of trypsin-like enzymes (ATLE) and gelatinases A and B were studied in the blood plasma and extracts from cardiac muscle, cerebral cortex and cerebellum of rats with cardiomyopathy caused by anthracycline antibiotic doxorubicin against the background of preventive application of corvitin and α-ketoglutarate. ATLE significantly increased in blood(More)
We studied the levels of lymphocyte surface-associated sialylglycans and the expression of neuraminidase NEU1 and sialyltransferase ST6GAL1 genes in lymphocytes in erythremia patients and healthy donors as well as the levels of sialic acids in plasma and sialylation of alpha-acid glycoprotein and fibronectin. Moreover, we also investigated the type of(More)
