Abstract

The invention discloses a serum-free culture medium suitable for immune cell large-scale culture, and belongs to the field of cell biology and medical immunology. The serum-free culture medium takes an RPMI1640 culture medium as a basis, additive components are further contained and include HEPES, phenol red sodium salt, L-glutamate and sodium bicarbonate. Insulin, transferrin, selenium, human albumin and interleukin-2 can be further added. Components contained in the culture medium are chemical defined components, no animal serum components are contained, and the serum-free culture medium is suitable for large-scale culture of immunity cells and is high in clinical safety and good in proliferation effect.

Description

technical field [0001] The invention belongs to the fields of cell biology and medical immunology, and in particular relates to a serum-free medium suitable for culturing all immune cells. Background technique [0002] With the rapid development of immune cell biology and immune molecular biology, somatic cell immunotherapy has become one of the important means of adjuvant therapy for tumor patients after radiotherapy and chemotherapy. All have good effect. [0003] Somatic cell immunotherapy is a biological therapy that injects immune cells with anti-tumor activity into tumor patients to directly kill the tumor or stimulate the body's anti-tumor immune response to achieve therapeutic effects. In vitro manipulations include cell passage, expansion, modification, screening and treatment with drugs or other treatments that can change the biological behavior of cells in vitro. Somatic cells manipulated in vitro can be used for tumor treatment and also for tumor prevention. ...
