Isolation of Human T Lymphocytes by a Negative Selection Procedure

Abstract
A single step method to isolate human T [thymus-derived] lymphocytes was achieved using a rosette technique to deplete non-T lymphocytes. Erythrocytes coated simultaneously with Ig[immunoglobulin]G and complement were used to form rosettes with cells bearing such receptors during a short incubation period and the rosetting cells removed by gradient centrifugation. T lymphocytes were isolated (> 96% T cells) without much experimental manipulation and in good recovery (mean 60%, range 40-75%).
