Gene editing is a new technology for site-specific modification of genome. Using this technology, we can locate a specific site in the genome, cut the target DNA and insert a new gene fragment at this site. The project not only simulates the natural mutation of genes, but also modifies and edits the original genome to truly complete gene editing. Next redbert (Beijing) Biotechnology Co., Ltd. will introduce the technology and principle of gene editing.
Genetic engineering technology is the core of modern biotechnology. Since its birth in the 1970s, it has been rapidly developed and widely used in recent decades. It has the characteristics of fundamentally changing the performance of biology and food, and has attracted more and more attention of food science and technology workers. The concept of food has also changed from agricultural food and industrial food to genetic engineering or biotechnology food. In the 21st century, biotechnology with genetic engineering as the core will bring a revolution to the food industry. Next redbert (Beijing) Biotechnology Co., Ltd. will introduce the application of genetic engineering technology in food.
Humanized antibodies are mainly mouse monoclonal antibodies modified by gene cloning and DNA recombination. Most amino acid sequences are replaced by human sequences, which basically retains the affinity and specificity of parental mouse monoclonal antibodies, reduces their heterogeneity, and is conducive to their application in human body. After years of research and improvement, people have created and improved a variety of humanized antibody technologies, such as reconstituted antibody, surface remodeling antibody, de immunized antibody, chain replacement antibody and so on. Let's introduce the expression system of humanized antibody by redbert (Beijing) Biotechnology Co., Ltd.
Since the 1950s, a large number of tumor immunology studies have proved that the body has a specific immune response to tumor, which has opened up a new way for tumor treatment. Immunotherapy has become one of the important means of tumor treatment. Experimental and clinical studies have shown that the immune cells of the body can clear tumors. After surgical resection of the primary tumor, immunotherapy should be used to kill the residual tumor cells and eliminate the factors of recurrence and metastasis. Next redbert (Beijing) Biotechnology Co., Ltd. will take us to understand the development and current situation of tumor immunotherapy.
