title: A method for the preparation of imprints from the nasal mucosa.
abstract: Important immunological reactions take place on the surface of mucosal membranes. Improved methods for the sampling and quantitative study of the cells taking part in these reactions are therefore desirable. We here describe a new technique for the preparation of imprints from the nasal mucosa. The method utilizes a plastic film coated with a thin layer of an albumin-glycerol mixture to improve cell adherence to the surface. The membrane is gently pressed onto a defined portion of the mucous membrane. Fixation and staining procedures are performed on the plastic film, which is then mounted on a slide and covered by a coverslip. The preparations have excellent optical properties and specific cell types can be easily studied, quantified and related to the specific area of the mucosa from which the imprint was taken.
