    The present paper describes two simple procedures which enhance immunohistochemical staining. One is to cover the sections with a plastic film to keep the serum uniformly distributed and minimize its evaporation. Secondly, rocking of the slides has been introduced, causing the serum to flow back and forth under the plastic film. Using this system, it has been possible to test for the effect of mixing on an immunohistochemical reaction (the demonstration of calcitonin in thyroid C cells). It has been found that mixing definitely enhances the reaction during the first 8 h. No effect of serum volume was observed.

    Immunocytochemistry and Immunohistochemistry

    Immunocytochemistry (ICC) and immunohistochemistry (IHC) are techniques that use antibodies to check for specific proteins or antigens in a sample. The technique was first published by Albert Coons in 1941 to detect the presence of pneumococcal antigen in tissue sections from mice infected with Pneumococcus. Immunocytochemistry helps localization of proteins or antigens in individual cells like blood cells, stem cells, etc., while immunohistochemistry does the same for tissue samples.
