title: An 'on the slide' modification of the De Olmos-Heimer horseradish peroxidase method.
abstract: The De Olmos-Heimer horseradish peroxidase method has been simplified without losing its sensitivity. The modification involves the use of cryostat sections and omitting several steps from the original procedure. The modification is especially suitable for small pieces of tissue that would otherwise require imbedding.
