title: An alginate matrix double-embedding method for paraffin sectioning of minute specimens.
abstract: A method has been devised for placing minute specimens in viscous aqueous sodium alginate solution, which is polymerized in 0.25 molar calcium chloride. The resulting matrix can then be dehydrated, embedded, and sectioned, maintaining the orientation of the specimens. The sectioned alginate can be dissolved in 0.1 molar EDTA if desired. Tissue sections respond to normal staining procedures.
