Abstract
Tissue fixatives, such as diazolidinyl urea, which are free of aldehydes and toxic chemicals are described. When used, either in aqueous or alcoholic solutions, good tissue preservation is attained. In addition, tissue antigens are retained which makes the fixative useful for immunostaining procedures.
