Detection and primary characterization of Rothia amarae in a suspension culture of Arabidopsis thaliana (Heynh.) cells

The presence of non-pathogenic bacterial microflora in Arabidopsis thaliana suspension culture has been shown to coexist latently with plant cells for a long time. According to the results of 16S rRNA sequencing, it was shown that the detected bacteria belong to the species Rothia amarae. Using microbiological, microscopic and immunochemical methods, the correspondence of the obtained strain to the species Rothia amarae was also confirmed.

Preliminary Immunochemical Studies to Detect Lard

Detection of lard in food using immunochemical methods has been carried out. This method has been applied and developed in food analysis. The purpose of this study was to detect the presence of lard in food. The method used was immunochemical which in this case is tested to its application in food analysis. The principle method is based on the antigen-antibody reaction, between lipids as antigens that can be deposited by antibodies in the agar medium. Antibodies were obtained by inducing lard into the blood vessels of rabbits. This method is based on the antigen-antibody reaction between fat as an antigen and antibodies that contain anti-lard as reagents and the occurrence of precipitation in agar media. The antibody was obtained by inducing lard, pork broth, and pig plasma into the blood vessels of rabbits. The results of this study were significant.

Immunochemical methods for detection of organophosphorus compounds

Organophosphorus compounds (OP) are found in environmental objects and food products. Due to their high toxicity and inhibition of cholinesterase activity, it is necessary to control residual amounts of OP. The most common methods for determining OP are gas and liquid chromatography with various detection methods. However, chromatographic analysis is lengthy, requires complex sample preparation and expensive equipment, which limits its use for screening a large number of samples and continuous monitoring of the content of OP. To detect the OP, it is necessary to use High Throughput Screening methods, using simple, fast and inexpensive analysis methods. Currently, immunochemical methods are increasingly used to determine OP. These methods are based on the recognition of the analyte (antigen) by specific receptors (antibodies) with the formation of the antigen-antibody complex and the measurement of the analytical signal generated by the immunochemical test system in response to complex formation, which leads to high sensitivity and specificity of the analysis.
