Description

Microglia, one of the glial cell types in the CNS, is an important integral component of the neuro-glial cell network [1]. They have been observed in the brain parenchyma from the early stage of development to the mature state. Microglia act as brain macrophages when programmed cell death occurs during brain development or when the CNS is injured or pathologically damaged. Microglia can be considered the main cell in brain immune surveillance, can present antigens in the molecular context of MHC class II expression to CD-4 positive T cells, are capable of Fc-mediated phagocytosis, and share many common antigens with hemopoietic and tissue macrophages [2]. Furthermore, there is accumulating evidence that microglia are involved in a variety of physiological and pathological processes in the brain by interacting with neurons and other glial cells and through production of biologically active substances such as growth factors, cytokines, and other factors [3].

MM from ScienCell Research Laboratories are isolated from neonate day two CD57BL/6 mouse brain tissue. Cells are harvested after purification and delivered frozen. Each vial contains >1 x 10^6 cells in 1 ml volume. MM is characterized by immunofluorescent method with antibody to OX-42 (CD 11b/c). MM is negative mycoplasma, bacteria, yeast and fungi. MM is guaranteed to further culture in the conditions provided by ScienCell Research Laboratories.

Recommended Medium

It is recommended to use Microglia Medium (MM, Cat. No. 1901) for the culturing of MM in vitro

Product Use

MM is for research use only. They are not approved for human or animal use, or for application in in vitro diagnostic procedures.

Storage

Transfer cells directly and immediately from dry ice to liquid nitrogen upon receiving and keep the cells in liquid nitrogen until cell culture is needed for experiments.

Shipping

Dry ice or gel ice.
