HRE-luciferase (HRE-Luc in short) was a gift from Navdeep Chandel (Addgene plasmid #26731; http://n2t.net/addgene:26731; RRID: Addgene_26731) 26 (link). Plasmid pcDNA3.1 Flag-HIF1B (#930) was a gift from James Brugarolas (Addgene plasmid #99916; http://n2t.net/addgene:99916; RRID: Addgene_99916) 27 (link). Human PPARD was initially amplified from cDNA template and then cloned into p3XFLAG-CMV™-10 (Sigma, E7658) fused with Flag or HA tag. To generate the truncated domains of PPARD (Flag-DBD and Flag-LBD) as previously described 28 (link), relevant fragments were amplified by indicated primers listed in Table S1 and then all were cloned into p3XFLAG-CMV™-10.

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.
