Red blood cell rosetting enables size-based separation of specific lymphocyte subsets from blood in a microfluidic device

Abstract

cells but declined with increasing cell rarity. Unlike the immunodensity approach, RESIZE required neither centrifugation nor cell washing after the separation and was ∼2.5-fold faster when processing the same sample volume. The results of this study suggest that integration of the RESIZE approach for high-yield isolation of lymphocyte subsets from blood could significantly streamline the manufacturing workflow and thus have a potentially transformative impact on the cost and availability of novel cellular immunotherapies.
