Phospho-Progesterone Receptor (Ser345) Antibody

Phospho-Progesterone Receptor (Ser345) Antibody detects endogenous levels of Progesterone Receptor only when phosphorylated at Ser345.<br>Tissue Specificity: In reproductive tissues the expression of isoform A and isoform B varies as a consequence of developmental and hormonal status. Isoform A and isoform B are expressed in comparable levels in uterine glandular epithelium during the proliferative phase of the menstrual cycle. Expression of isoform B but not of isoform A persists in the glands during mid-secretory phase. In the stroma, isoform A is the predominant form throughout the cycle. Heterogeneous isoform expression between the glands of the endometrium basalis and functionalis is implying region-specific responses to hormonal stimuli.
