Monoclonal antibodies are called monoclonal antibodies, and their corresponding polyclonal antibodies are called polyclonal antibodies. If cells can be cultured to produce specific antibodies, a cell population formed by the division and proliferation of a single cell can be obtained, which is called monoclonal antibody. Single cell cloning involves the synthesis of an antibody against an antigenic determinant called a monoclonal antibody. Natural antigen molecules contain a variety of antigen-specific epitopes to stimulate the body's immune system. Multiple B cell clones in the body are activated, and the antibodies produced contain immunoglobulins with a variety of different epitopes, which are called polyclonal antibodies.
Antibody engineering drugs are also called antibody drugs, monoclonal antibody therapeutic agents and antibody therapeutic agents. Monoclonal antibodies, antibody fragments, genetically engineered antibodies, antibody immune conjugates or antibody fusion proteins prepared by cell engineering or genetic engineering methods for treatment are called antibody engineering drugs. Let's introduce antibody engineering drugs by redbert (Beijing) Biotechnology Co., Ltd.
Synthetic biology is a new comprehensive interdisciplinary subject, involving biochemistry, physical chemistry, molecular biology, systems biology, genetic engineering, engineering and computational science. It aims to design and construct engineered biological systems, including gene circuits, signal cascades and metabolic networks. It can process information, manipulate compound synthesis, manufacture materials, produce energy, provide food, improve human health and living environment, and obtain new cell behavior in a predictable and reliable way. Next redbert (Beijing) Biotechnology Co., Ltd. will introduce the development and Prospect of synthetic biology.
A large number of studies have proved that the occurrence of tumor is the result of the joint action of multiple factors, stages and genes. It is characterized by the interaction of factors (environmental factors, such as physics, chemistry, biology, genetics, immunity, age and gender, etc.). Some are carcinogenic, that is, they induce malignant transformation of cells, while others promote cancer. The occurrence and development of tumor has experienced the stages of initiation, promotion, invasion and metastasis. Moreover, a variety of oncogene activation and tumor suppressor gene inactivation may occur at each stage. It is characterized by excessive proliferation, abnormal differentiation and blocked apoptosis. Next redbert (Beijing) Biotechnology Co., Ltd. briefly introduces the factors leading to tumor formation?
