Isolation of Primary Mixed Glial Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
The primary mixed glial cells were prepared from neonatal C57BL/6J mouse pups as reported previously (Ma et al., 2011 (link)). In brief, after carefully removing the meninges, the neonatal brain was disintegrated by pipetting. The cell suspension was seeded in 10-cm culture dishes at a density of one brain per dish. Dulbecco's modified eagle medium (DMEM, 10 mL; Sigma, St. Louis, MO, USA) containing 10% fetal bovine serum (FBS; ICN Biomedicals, Aurora, OH, USA) was added to each dish. After14 days in vitro, primary mixed glial cells were dissociated by trypsinization, and the cell suspension was plated in 15.6-mm culture dishes for treatment with Cat C (R&D Systems, Minneapolis, MN, USA); each culture dish contained 1 × 106 cells.

Cells of the SH-SY5Y human neuroblastoma cell line, which were purchased from American Type Culture Collection (Manassas, VA, USA), were cultured in DMEM/F-12 mixture supplemented with 10% fetal bovine serum (FBS, ICN Biomedicals, Eschwege, Germany), 2 mM L-glutamine, and 1% antibiotic and antimycotic solution (Sigma, St. Louis, MO, USA) in a humid atmosphere of 5% CO2 and 95% air at 37°C. To determine the toxicity of the reagents, the cells were treated with freshly prepared H2O2 (from 30% stock) at concentrations ranging from 5 to 500 μM (diluted with sterile purified water), and RNSP was tested at concentrations ranging from 0.01 to 100 ug/mL (diluted with methanol or sterile purified water) for different treatment times.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
