Characterization of SCLC Cell Lines

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human SCLC cell lines (H146, H187, H128, H69, H209, DMS153, H526, DMS114, and DMS53) were purchased from the American Type Culture Collection (ATCC, Manassas, VA). Cell line purity was authenticated by short tandem repeat (STR) profiling at the Winship Cancer Institute Genomics Laboratory. The authenticity was confirmed for all cell lines except H128. The STR pattern for H128 was not consistent with the published references but consistent with the profiles for NCI-H60 (ATCC CRL-5821) and NCI-N417 (ATCC CRL-5809). It is noteworthy that we did not have the NCI-H60 and NCI-N417 in our lab throughout the duration of this work. Cells were grown as suspension or partially attached monolayer culture in RPMI 1640 medium supplemented with 5–10% fetal bovine serum at 37°C under humidified condition of 5% CO2 and 95% air.

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.
