title: A simple and convenient method for gaining pure populations of lymphocytes at the first mitotic division in vitro.
abstract: This paper describes a simple method for obtaining pure populations of human lymphocytes at the first in vitro mitotic division (M-1) by continuous treatment with colchicine or colcemid. When colchicine (7.2 x 10(-8) M) or colcemid (4.8 x 10(-8) M) was added to cultures 0-24 h after initiation, cultures harvested at 54 h had more than 99.9% of mitotic cells in the first metaphase (M-1). We showed that not only more analyzable M-1 cells may be obtained, but staining for sister-chromatid differentiation may be avoided.
