Breast Cancer Cell Line Characterization

Check if the same lab product or an alternative is used in the 5 most similar protocols
The human breast cancer cell lines (BT20, MCF7, HCC202, T47D, MDA-MB-453 and MDA-MB-436) were obtained from ATCC. Prior to use, cell line authentication was performed by either STR profiling at Dana-Farber Cancer Institute or by Fluidigm based fingerprinting with a panel of SNPs at The Broad Institute. Cell lines were tested for mycoplasma with the MycoAlert PLUS Mycoplasma Detection Kit (Lonza LT07) according to manufacturer’s instructions. Mouse breast tumor cell lines were established from 4 different MMTV-PyMT tumor bear mice. Mouse breast tumor cell line 7333 was implanted into wild-type littermates and once the tumor formed it was removed and used to generate the tumor cell line “MMTV”. All cells were plated at 1E4 cells/well in a 96 well plate. Cells were treated for 48 hours and CellTiter-Glo was used to assess cell viability.

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.
