Abstract:
Objective:To preparation TREM2-specific monoclonal antibodies and to evaluation their properties and applica-tions lay a foundation for the development of druggable antibodies against TREM2 targets.Methods:The GST fusion protein containing the extracellular segment of TREM2 was expressed and purified,which was used as antigen to immunize mice.The mouse with high antiserum titer was used to generate specific monoclonal antibodies against TREM2 through cell fusion and monoclonal screening.The specificity and affinity of the monoclonal antibodies and their applications in different immunological experiments were detected.Results:A total of 29 strains of anti-TREM2 monoclonal antibodies were obtained,of which 24 strains could specifically bind to TREM2.The EC50 of antibodies were calculated above nanomolar.These monoclonal antibodies could be used for specific detection of TREM2 in Western blot,immunoprecipitation,flow cytometry and immunofluorescence experiments.Conclusion:Monoclonal anti-bodies against TREM2 with high affinity and specificity are successfully generated,which lay the foundation for the research and the development of antibody drugs targeting TREM2.
