title: HLA-D typing of human lymphocytes using frozen and thawed spermatozoa.
abstract: A method is described for the preservation of haploid populations of human spermatozoa in liquid nitrogen for their subsequent use as stimulators in HLA-D (SL) lymphocyte typing. The typing results obtained using thawed spermatozoa correlated well with those obtained when using fresh sperm and also with other cellular typing methods.
