Estrogen receptors are commonly over-expressed in cancers. Clone PPG5/10 recognizes Estrogen Receptor Beta (ERβ) 1 and is useful in determining the expression of ERβ1 in cancer cells, mainly via immunohistochemistry.

Clone PPG5/10 used to detect expression of ERβ1 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; main panels show closely adjacent sections from three cancer blocks to allow direct comparisons. (Collins, F et al.)
Dilution used: 1:40

Clone PPG5/10 used to detect expression of ERβ1 in cancer tissue by immunofluorescence
Image caption: Expression of PR paralleled that of ERα not ERβ… C. Fluorescent co-localisation as carried out using antibodies specific for ERα or ERβ1 (both green) and PR (red). The cancers illustrated were classified as well (code 1614), moderately (code 1930) or poorly (c, codes 0001 and 1176) differentiated; at least 8 samples were analysed in each group. Co-expression was detected as yellow/orange immunofluorescence. In the well and moderately differentiated cancers expression of PR was most intense in epithelial cells and broadly overlapped with that of ERα (e.g. in cells indicated by arrows)… (Collins, F et al.)
