Addgene Depositors Get More Citations

“Professor Feng Zhang’s original 2013 gene editing paper on CRISPR/Cas amassed nearly 2,400 citations in its first four years (1). In addition to publishing in Science, Professor Zhang deposited the associated plasmids with Addgene. Since then, Addgene has filled over 6,500 requests for these plasmids. While clearly an outlier, this story had us wondering: is there a larger trend here? Do papers associated with Addgene deposits accumulate more citations than those without Addgene deposits? Even more interestingly, could we tell if depositing a plasmid with Addgene causes a paper to get cited more? …So what do we find [from Web of Science]? Lots more citations for the papers with plasmids deposited at Addgene – typically about four times as many as papers without plasmids deposited with Addgene….”
