Stereology: Probing for Precision


Stereology is a tool for obtaining unbiased estimates of object numbers and/or sizes within three-dimensional regions of interest.  For biological samples, quantitative measurements are potentially more objective and accurate when compared to traditional semi-quantitative grading of findings by pathologists (i.e., scoring of morphologic changes as minimal, mild, moderate, or severe).  Although both approaches require high […]

Immunostaining Assay Optimization – Tackling Intrinsic Study Variables


Immunohistochemistry or Immunofluorescence (IHC/IF) is employed routinely for investigative and diagnostic evaluations of antigen-antibody interactions within cells or tissues. While most IHC/IF target antigens are proteins, other antigenic biological substrates can also be recognized by antibodies (e.g., carbohydrates, lipids, or nucleic acids). Accurate and reproducible results are achieved when procedures used to identify and localize […]
