Formalin fixed, paraffin embedded human breast cancer biopsy stained with Mouse anti Human estrogen receptor beta5 antibody followed by HRP polymer detection and DAB substrate development following heat mediated antigen retrieval using citrate buffer at pH6.2 (high power)
Published customer image: 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. All proteins were immunolocalised to cell nuclei (see higher power inserts in panels e, f, c and d respectively). In the well and moderately differentiated cancers expression was most intense in epithelial cell layers (arrowheads, panel A and inserts). Note that ERa was low/absent in poor grade cancers (J) but immunoexpression of ERbeta1, 2, 5 was readily detected (K. L, M). Inserts in panels K, L, and M show negative controls for ERbeta1, ERbeta2 and ERbeta5 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.From: Collins F, MacPherson S, Brown P, Bombail V, Williams AR, Anderson RA, Jabbour HN, Saunders PT.
