: This may be a very primary question, but check a few books without any information, the literature is an understatement, as if it were too primitive. However, I really do not know how to operate this method - esterase concentration, formulation and dyeing time and so on, look forward to the echo of your comrades. Thank you.
: I've done it before, I've done lymphocytes. But macrophage methods are the same and are more likely to produce results.
