Check if the same lab product or an alternative is used in the 5 most similar protocols
Human gastric cancer cell lines MGC-803 was brought from the Shanghai Genechem Co., Ltd. (GENE, Shanghai, China) and SGC-7901 was purchased from the Shanghai Biowing Applied Biotechnology Co., Ltd. (BIOWING, Shanghai, China). The cells were cultured in Dulbecco's modified Eagle's medium (DMEM, Gibco, Grand Island, NY) supplemented with 10% fetal bovine serum (FBS, Gibco, Grand Island, NY). When the cell density reached 70%, the cells were treated with 2 μM, 10 μM, or 20 μM ISO (HARVEST, Shanghai, China) or 20 μM, 40 μM, or 50 μM ICI118,551 (a specific β2-AR antagonist) (Abcam, #ab120808, US), while the control group was given matching normal saline. MGC-803 cells and SGC-7901 cells were harvested and prepared for the next trial after 12 hours and 24 hours, respectively.

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.
