Background
CD45RO is an important cell surface marker in immunology that belongs to the CD45 family (also known as Leukocyte Common Antigen, LCA). CD45 is a highly polymorphic transmembrane protein primarily expressed on the surface of white blood cells, including T cells, B cells, natural killer (NK) cells, monocytes, and granulocytes, and plays a crucial role in lymphocyte development, activation, and signaling. Specifically, CD45RO is an isoform of CD45 that is highly expressed on memory T cells but expressed at lower levels or not expressed on naive T cells. Memory T cells are T cells that have been activated and survived during previous immune responses, enabling them to rapidly and strongly activate upon re-encountering the same antigen, thus accelerating and enhancing immune responses. Therefore, CD45RO is often used to distinguish and identify memory T cells. It serves as an important marker in immune phenotyping analysis, disease diagnosis, immune response monitoring, and immunotherapy research.

Goat Anti - Mouse IgG Alexa Fluor® 488 was used as the secondary antibody. Then cells were stained with CD45RA - PE/Cy5.5 separately. Gated on viable lymphocytes.
Immunohistochemistry
IHC shows positive staining in paraffin-embedded human spleen. Anti-CD45RO antibody was used at 1/1000 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.

Immunocytochemistry
ICC shows positive staining in HuT 78 cells (top panel) and negative staining in Jurkat cells (below panel). Anti-CD45RO antibody was used at 1/500 dilution (Green) and incubated overnight at 4°C. Goat polyclonal Antibody to Rabbit IgG - H&L (Alexa Fluor® 488) was used as secondary antibody at 1/1000 dilution. The cells were fixed with 100% ice-cold methanol and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue). Counterstain with tubulin (Red).
Immunofluorescence
IF shows positive staining in paraffin-embedded human tonsil. Anti-CD45RO antibody was used at 1/200 dilution (Green) and incubated overnight at 4°C. Goat polyclonal Antibody to Mouse IgG - H&L (Alexa Fluor® 488) was used as secondary antibody at 1/1000 dilution. Counterstained with DAPI (Blue). Heat mediated antigen retrieval with EDTA buffer pH9.0 was performed before commencing with IF staining protocol.
