Exploring Podocyte Lipidosis and Apoptosis

Check if the same lab product or an alternative is used in the 5 most similar protocols
The mouse podocyte cell line MPC5 was kindly provided by Professor Ruan (Center for Nephrology, Royal Free and University College Medical School, London,
United Kingdom). Cells were cultured on rat tail type I collagen (Millipore, USA) in RPMI-1640 (Gibco, USA) supplemented with 10% fetal bovine serum (PAN, Germany), 100 U/l penicillin (Gibco, USA), 0.1 mg/ml streptomycin (Sigma, USA), and 100 IU/ml interferon-γ (R&D, USA) at 33°C in 5% CO2 for 14 days. Thereafter, cells were cultured in the same conditions, except that the medium lacked interferon-γ. Cells were treated with human LDL (200 μg/ml, extracted from blood) with or without mouse IL-1β (20 ng/ml; PeproTech, USA) and a monoclonal anti-CD36 antibody (2 μg/ml; ab23680, Abcam, UK). Levels of CD36 and NLRP3 expression, lipidosis, and apoptosis were measured.

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.
