Presented by: Walaa Mal Histopathology teaching assistant. Skills in Anatomy TERMS ASSOCIATED WITH TISSUE PROCESSING HISTOLOGY-It is the microscopic examination or study of tissues. Melt the paraffin in an oven at 60°C in glass containers. Fixed and trimmed tissues are placed in processing cassettes and immersed in 98% formic acid (- for one hour ). To achieve this it is important that the tissue must be prepared in such a Histopathology Laboratory Services - Cognibrain provide an unparallel histology service through a network of histopathologists and animal researchers, you can be completely assured of proper tissue processing, high-resolution images, and the clarity of results. ** Certain tissue antigens (e.g., light chain immunoglobulins) are detectable only by frozen section immunohistochemistry. 7.2: Enclosed Type Tissue Processor Advantages zCan be used when the number of tissue blocks is limited zNon-availability of automated tissue processor Disadvantages zDifficult to use when large number of tissue blocks are to be processed zProper agitation of reagent not … Histopathology - Definition it is a branch of pathology which deals with the study of disease in a tissue section. The tissue undergoes a series of steps before it reaches the diagnosis. The same steps can be used for manual tissue processing. Tissue processing Tissue and organ preservation (perfusion fixation), tissue processing for microscopy (dehydration, embedding, cutting, mounting, coverslipping) Marco R. Celio March 21, 2011 .
