I hope this question is appropriate for this SE. When listing multiple cluster of differentiation (CD) markers to define a cell population, e.g. CD3+CD8+CD45+CD4-, is there a default order to put them in? I was recently told to list them numerically with the negative populations after the positive ones (i.e. CD3+CD8+CD45+CD4-). However, I have seen different orders in the literature and would personally prefer to order them by whatever I would consider most logical (e.g. CD45+CD3+CD8+CD4-).
