Glycophorin A (GPA) and Glycophorin B (GPB) are erythrocyte blood group determinants that minimize erythrocyte aggregation during the circulation of blood. Anti-Glycophorin A is useful for understanding erythroid cell development and identifying erythroid leukemias.

Cluster of differentiation 15 (CD15) is a carbohydrate adhesion molecule. Positive staining for CD15 and negative staining for leukocyte common antigen or other B- or T-cell lineage markers helps recognize Reed Sternberg cells (RSC) in Classical Hodgkin’s Lymphoma (CHL), and distinguishes it from Hodgkin-like neoplasms. CD15 does not stain mesotheliomas and is therefore most useful for distinguishing epithelial mesothelioma from adenocarcinoma.
Annexin A1 (ANXA1) is a membrane protein that plays a role in innate and adaptive immunity by controlling the biosynthesis of inflammation, prostaglandins, and leukotriene mediators. This target is overexpressed in 97% of all samples from patients with with hairy cell leukemia, and is absent in other B-cell lymphomas. High ANXA1 expression is frequently associated with advanced stage esophageal and esophagogastric junction adenocarcinoma, and is also linked to advanced and metastatic disease states.
LMO2, also known as LIM-Only transcription factor 2, RBTN2, or TTG2, is an oncoprotein that is expressed in normal germinal center B-cells, as well as bone marrow hematopoietic precursors and endothelial cells. LMO2 plays a role in angiogenesis and hematopoesis, and its expression has been detected in erythroid and myeloid precursors, megakaryocytes, and also in lymphoblastic and acute myeloid leukemias. LMO2 protein expression has been noted in diffuse large B-cell lymphoma, the most common adult non-Hodgkin lymphoma, as well as follicular lymphoma, a neoplasm derived from germinal center B-cells that accounts for a number of cases of non-Hodgkin lymphomas.
Cytokeratin 18 (CK18) is present in simple, glandular, and transitional epithelial cells, but is absent in stratified epithelial cells. CK18 usually multimerizes with Cytokeratin 8, and Anti-Cytokeratin 18 is useful for detecting adenocarcinomas of simple and glandular epithelium origin, as well as poorly differentiated squamous carcinoma cells.
