I am writing a scientific manuscript in which I have to describe an experimental protocol. The used sentence should show the priority of picking up biological samples depending on their origins.
The used sentence structure might look like the following:
...was primarily selected according to sources from the Mus Musculus species sera, cells or tissues, then secondarily, from Rattus norvegicus species, and thirdly, from human sera.
Since this sentence structure was used previously in other manuscripts to describe the same protocol, it was detected as "high plagiarism" by authentic software tools.
My question is how to describe the same priority without using this common structure "primarily....secondarily,.... and thirdly,.... " ?
