Thymus - normal tissue. There is moderate nuclear labeling for Ki67 of about 50% of cortical lymphocytes (antibody diluted at 1:100, tissues fixed in Fekete's solution, heat-mediated antigen retrieval in citrate buffer at pH=6.0). Less nuclei are labeled for tissues fixed in Fekete's solution than for tissues fixed in Bouin's solution. In addition, there is strong artifactual staining of the keratinocytes of a Hassal's corpuscule. Strong artifactual staining was also present in the corneal epithelium for tissues fixed in Fekete's solution. |
