Research progress in the rapid preparation of monoclonal antibodies of mouse hybridoma / 生物工程学报

Mouse hybridoma monoclonal antibody is the most commonly used antibody in immunology because of its stable source, easy preparation in later stage and high yield. The traditional time-consuming and laborious hybridoma preparation technology could not meet the growing market demand. In this paper, we describe the rapid preparation techniques involved in antigen design and screening, B cell enrichment and screening, transgenic myeloma cells, fusion technology improvement, positive hybridoma cell screening and rapid detection of monoclonal antibody performance, to provide a reference for rapid preparation of mouse hybridoma monoclonal antibody.

Application of CRISPR/Cas-based biosensors for detecting nucleic acid of pathogens / 生物工程学报

Clustered regularly interspaced short palindromic repeats/clustered regularly interspaced short palindromic repeats -associated protein (CRISPR/Cas) has been developed as a precise, efficient, affordable and sensitive nucleic acid detection tool due to its efficient targeted binding ability and programmability. At present, biosensors based on CRISPR-Cas system have shown excellent performance in the detection of nucleic acid of pathogens, which has attracted widespread attention, and is expected to replace the conventional detection methods. This review summarizes the latest research progress of biosensors based on CRISPR/Cas system for detecting nucleic acid of pathogens.
