For blocking the nonspecific binding sites, one has to use large volum amount of mouse
serum if purified IgG is not avalable. In this case the cellular concentration as well as
protein concentration will be changed, so for adjusting them again you'd better wash them
bafore the immunofleuorescent staining.
