3 methyladenine 3 ma

Manufactured by Topscience
Sourced in China

3-Methyladenine (3 MA) is a chemical compound that serves as an inhibitor of autophagy, a cellular process involving the degradation and recycling of damaged or unwanted cellular components. This compound acts by blocking the formation of autophagosomes, which are the vesicles responsible for transporting cellular material to the lysosome for degradation. 3-Methyladenine is commonly used in research applications to study the role of autophagy in various biological processes and disease states.

PC12 cells (RRID: CVCL_F659), which were commonly adopted in neurological disease research because of their neurogenicity, differentiability, high autophagic activity, and ease of experimental manipulation, were purchased from the Kunming Cell Bank of the Chinese Academy of Sciences (Cat# KCB93033YJ). U87-GFP-LC3 cells with stable GFP-LC3II expression (Macau University of Science and Technology, Macao SAR, China), a common cell line used to study autophagy, were cultured in DMEM containing 10% (v/v) fetal bovine serum and 0.1% penicillin/streptomycin in a humidified 5% CO2 atmosphere at 37°C. CRSE was used in cells at concentrations of 20, 40, and 80 μg/mL, rapamycin (Rapa; Cat# M1768, AbMole, Shanghai, China) at 10 μM and 3-methyladenine (3-MA; Cat# T1879, Topscience, Shanghai, China) at 2 μM. The duration of drug intervention was 24 hours under normal conditions.

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.
