Therefore, the volume of blood collected in each tube and adequate mixing of the sample into the additive are critical steps 5, 10 The HUPO Plasma Proteome Project 5 noted that there are too many variables to consider to make a universal statement on the best plasma SOPs for everyone to use, but the consideration of these variables in studyThe EDTA blood sample can easily last for at least 4 hours at room temperature and for few days inside the freezer Also, it helps to preserve the morphology of the blood cells Thus, the stability of the samples becomes high So,EDTA and NaHeparin samples processed with the EuroFlow bulk lysis protocol, stained and stored at 4 °C showed fairly stable expression of cell surface markers and distribution of the major leukocyte populations for up to 72 h Additional sample fixation (1% PFA, Fix &
