- W2334074564 abstract "Event Abstract Back to Event PHAGE MINI-ANTIBODIES AND THEIR USE FOR DETECTION OF MICROBIAL CELLS BY USING ELECTRO-OPTICAL SENSOR Olga I. Guliy1*, Lev A. Dykman1, Sergey A. Staroverov1, Viktor D. Bunin2 and Oleg V. Ignatov1 1 Institute of Biochemistry & Physiology of Plants & Microorganisms RAS , Russia 2 EloSystem GbR, Germany Nowadays, cell detection in molecular biology is performed with the help of genetic engineering technologies for cloning recognizing fragments (hypervariable immunoglobulin domains). These technologies are cheaper and can be competitive in selectivity with hybridoma technologies. One such method is antibody phage display. Obtaining the phage miniantibodies to Azospirillum brasilense Sp245 as example, and their use for detection of microbial cells by using electro-optical sensor. Measurements of cellular orientational spectra (OS) of the cells were measured with an ELUS EO analyzer at a wavelength of 670 nm. The preparation of miniantibodies to Azospirillum brasilense Sp245 surface antigens was made by using a combinatorial phage library of sheep antibodies. The prepared phage antibodies were used for cell detection by dot assay, electro-optical analysis of cell suspensions, and transmission electron microscopy. The results demonstrate that when A. brasilense Sp245 interacted with anti-LPS and antiflagellin mini-Abs, the magnitude of the EO signal changed considerably. It has been also found that the detection of cell A. brasilense Sp245 using the mini-antibodies is possible even in the presence of other cultures. The findings from this study can be used to develop a rapid test for the detection of bacterial cells and for the assessment of exposure of cell-surface antigenic determinants. The work was supported by Ministry of Education and Science of Russian Federation, project no. 8852.
