[ANALYSIS OF EFFECTIVENESS OF USINGJIgY FROM CHICKEN IN SANDWICH METHOD OF HBsAg TESTING].

Aim: Study antigen-binding ability of polyclonal antibodies (PCA) of chicken compared with monoclonal -antibodies (MCA) of mice in the model of interaction with HBsAg.

Materials And Methods: Mice MCA 18C8 and MKA F3/F4 (IgG) were used, effective in enzyme immunoassay sandwich method of HBsAg determination (with a minimal detection dose of 0.017 ng/ml), and affinity purified anti-HBsAg PCA of chicken (IgY), obtained from 2 immunized birds (PCA No.

[Effect of pH of Adsorption Buffers on the Number and Antigen-Binding Activity of Monoclonal Antibodies Immobilized on the Surface of Polystyrene Microplates].

The change in the concentration and antigen-binding activity of 28 monoclonal antibodies was studied after their adsorption on the surface of polystyrene microplates in buffers with different pH values (1.0, 2.8, 7.

Analysis of serotonin transporter in human platelets by immunoblotting using site-specific antibodies.

We have produced a panel of site-specific antibodies recognizing different regions of the human serotonin transporter (SERT). This panel included: 1) monoclonal antibodies 23C5 (mAbs 23C5) to the C-terminal region (amino acid residues 597-630); 2) polyclonal antibodies (pAbs) to the N-terminal region (amino acid residues 69-83); 3) pAbs to the region (amino acid residues 86-100) in the beginning of the first transmembrane domain (TMD). The antibodies were produced using recombinant proteins and synthetic peptides (containing certain sequences of SERT) as antigens.
