Mechanisms of Ageing and Development
|September 1, 1988
Abstract:
Mouse red blood cells (RBC) can be fractionated according to their size by counterflow centrifugation. The mean corpuscular hemoglobin content and the enzyme activities (ASAT, LDH, PK and acetylcholinesterase) increase when the mean corpuscular volume (MCV) rises. However, the in-vivo survival of size-separated RBC is similar whatever their MCV is; thus, counterflow centrifugation is not a suitable procedure to achieve an age fractionation of mouse RBC. Moreover, RBC subpopulations collected by counterflow centrifugation are different from those obtained when RBC are fractionated according to their density.
