Background Information

Estrogen receptor-beta (ESR2) is a member of the superfamily of nuclear receptors, which can transduce extracellular signals into transcriptional responses. It binds estrogens with an affinity similar to that of ESR1, and activates expression of reporter genes containing estrogen response elements (ERE) in an estrogen-dependent manner. DNA-binding by ESR1 and ESR2 is rapidly lost at 37 degrees Celsius in the absence of ligand while in the presence of 17 beta-estradiol and 4-hydroxy-tamoxifen loss in DNA-binding at elevated temperature is more gradual. ESR2 exists various isoforms and range of calculated molecular weight of isoforms is 50-60 kDa. The experiment detected two bands for ESR2 in isolated human germ cells, one at 60 kDa and a weaker one at 50 kDa(PMID:14766008).

No specific reaction - positive reaction should be visible only in nucleus but in our staining is present also in the cytoplasm. Moreover, we used the material from knockout mice without ESR2 and we observed response in this slices to this receptor. I have a problem with attaching a photo file.
