Increased incidence of positive tests for estrogen binding in mammary carcinoma specimens transported in liquid nitrogen

F Muschenheim et al. Am J Clin Pathol. 1978 Nov.

Abstract

Use of a liquid nitrogen container for convenient transport of frozen mammary carcinoma tissue for hormone-receptor assays is described. The container can be used in dry or wet mode and is appropriate for all types of transport, including air. Experience shows a significantly higher incidence of positive tests on specimens transported by this means than on specimens transported in dry ice.
