Check if the same lab product or an alternative is used in the 5 most similar protocols
Normal human fibroblasts isolated from healthy newborn foreskins were provided by Dr. Jin-Ho Chung (IRB No. H-1101-116-353 from the School of Medicine, Seoul National University, Korea) and maintained in Dulbecco’s modified Eagle’s medium (DMEM) (LM001-11; Welgene, Korea) supplemented with 10% fetal bovine serum (S-FBS-US-015; Serana, Australia) at 5% CO2 and 37°C. The DMEM contained no glucose (LM001-79; Welgene) to simulate glucose deprivation. Cells were passaged at a 1:4 dilution until they stopped dividing at passage 32 to obtain a fibroblast population at replicative senescence. Fibroblasts mid-passage (between 20 and 24) were pulsed with 0.25 μM doxorubicin for 4 h and chased in fresh medium replaced every two days for chemically induced senescence. On Day 5, cells began expressing senescence phenotypes similar to previous studies (Song et al., 2005 (link)). Chemicals purchased from the following sources were used at 200 nM, 250 nM, 50 μM, 0.25 μM, 0.2 μM, and 0.5 μM doses, respectively: bafilomycin A1 from Enzo Life Science (USA) (BML-CM110-0100); Torin-1 from Biorbyt (UK) (orb146133); chloroquine (CQ; C6628), doxorubicin (D1515), and wortmannin (W1628) from Sigma-Aldrich (USA); and KU60019 from Selleckchem (USA) (S1570).

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.
