Immunohistochemistry (IHC) is used to detect and localize antigens (e.g., proteins) in cells or tissue sections by exploiting the principle of antibodies binding specifically to antigens in biological tissues.

ChemPartner has accumulated extensive hands-on experience in histopathology that provides support to research in oncology, immunology, inflammation, neuroscience, metabolic and cardiovascular diseases, toxicology, and the discovery of large and small molecule drugs.

ChemPartner is dedicated to providing high-quality and efficient services for IHC assay development, protocol validation, single/double staining, image collection, and data analysis/interpretation. For non-commercial antibodies, ChemPartner also provides full assay development for validation and optimization before formal study.

Representative Images of IHC Double Staining

  • TH(Pink): Tyrosine Hydroxylase, Millipore, AB152, Rabbit IgG; α-Synuclein Phospho (Ser129)(Brown): Biolegend, #825701, Mouse IgG2a
  • Blue arrows indicate the positive cells of co-staining; Phosphorylation of α-Synuclein Ser-129 is selective and extensive in synucleinopathy lesions
