immune escape in B cell lymphoma

HI, I want help with my methodology to make some add and change in two parts that I already writ it ( sample and data collection and protocol of the lab work ) in this project. ( I already writ my impact and introduction) I will send one of the article to let you understand the criteria of how I want the the protocol look like.

My supervisor dose not want the protocol like toking about the producer, he want to writ about the principle. also, in the sample collection and data, I just used normal healthy human sample, I did not use any sample from B CELL LYMPHOMA patient, that’s why I want to make change on this part.
