High degree of consistency was observed between the results obtained via the method under consideration and those obtained via control methods at different stages of cholera chemical vaccine production. It was shown that the CHO-K1 cell line is the most promising substitute for biomodels at the intermediate stages of control of active cholera chemical vaccine components. The developed methodological approach was first proposed for use at the stages of cholera chemical bivalent vaccine manufacturing. cell culture, Vibrio cholerae, cholera chemical vaccine, production control, cholera.

Abstract Background H7 subtype avian influenza has caused great concern in the global poultry industry and public health. The conventional serological subtype-specific diagnostics is implemented by hemagglutination inhibition (HI) assay despite lengthy operation time. In this study, an efficient, rapid and high-throughput competitive enzyme-linked immunosorbent assay (cELISA) was developed for detection of antibodies against H7 avian influenza virus (AIV) based on a novel monoclonal antibody specific to the hemagglutinin (HA) protein of H7 AIV. Results The reaction parameters including antigen coating concentration, monoclonal antibody concentration and serum dilution ratio were optimized for H7 antibody detection. The specificity of the cELISA was tested using antisera against H1 ~ H9, H11 ~ H14 AIVs and other avian viruses. The selected cut-off values of inhibition rates for chicken, duck and peacock sera were 30.11, 26.85 and 45.66% by receiver-operating characteristic (ROC) curve analysis, respectively. With HI test as the reference method, the minimum detection limits for chicken, duck and peacock positive serum reached 20, 21 and 2− 1 HI titer, respectively. Compared to HI test, the diagnostic accuracy reached 100, 98.6, and 99.3% for chicken, duck and peacock by testing a total of 400 clinical serum samples, respectively. Conclusions In summary, the cELISA assay developed in this study provided a reliable, specific, sensitive and species-independent serological technique for rapid detection of H7 antibody, which was applicable for large-scale serological surveillance and vaccination efficacy evaluation programs.

In order to prepare the monoclonal antibody against 1,5-anhydro-glucitol (1), it was conjugated with bovine serum albumin (BSA), human serum albumin (HSA) or chicken lysozyme (CL) using succinate orβ-alanine succinate as a spacer to produce individual antigen conjugates. The number of hapten contained in each antigen conjugate was determined by matrix-assisted laser desorption/ionization tof mass (MALDI-tof-MS) spectrometry. The formation of monoclonal antibody (MAb) was also discussed.
