The cell lines used within this study have been purchased from known cell providers, and are an expansion of the original primary cell culture. These cell lines are therefore not considered relevant material under the Human Tissue Act and do not require ethics approval.

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.
