Clone 57/3 used to detect expression of ERβ2 in cancer tissue by IHC-P
Image caption: Immunoexpression of ERs in endometrial cancers. Tissues were classified as well (A-D), moderately (E-H) or poorly (J-M) differentiated; …immunoexpression of ERβ1, 2, 5 was readily detected (K. L, M). Inserts in panels K, L, and M show negative controls for ERβ1, ERβ2 and ERβ5 antibodies respectively generated using primary antibodies pre-absorbed with specific peptides used for immunisation. Asterisks (*) label the stromal compartment that was well defined in the well differentiated cancers. (Collins, F et al.)

Clone 57/3 used to detect ERβ2 expression in normal human liver by IHC-P
Image caption: Staining pattern of the ERß isoforms in human liver. In order to confirm the specificity of the ERß antibodies used in the study, we immunostained sections of human healthy liver, showing that ERß1 and ERß2 isoforms are not expressed, while specific nuclear ERß5 immunoreactivity is detected (magnification 20x and 40x). This pattern of ERß isoforms immunoreactivity is consistent with previous descriptions. (Ciucci, A et al.)

Image caption: Morphology and immunolocalization of aromatase and estrogen receptors in Leydig cell tumors (A and B) and control testis (C). A–C: Hematoxylin–eosin staining. A1–C1: Aromatase immunolocalization. A2–C2: ERα immunoreactivity. A3–C3: ERβ1 immunodetection. A4–C4: ERβ2 immunolocalization. L, Leydig cells; T, seminiferous tubule. (Carpino, A et al.)

Clone 57/3 used to detect expression of ERβ2 in ovarian cancer cells by Immunofluorescence
Image caption: A) Representative pictures for ERα, ERβ1, ERβ2, ERβ5, PR, and AR immunostaining in LGSOC patients (magnification 20 ×) and bar chart showing levels of hormone receptor expression (mean ± SEM, n = 25). Results are expressed as IRS (Immunoreactive receptor score).
