PREB Antibody (JE64-56)

Western Blot: PREB Antibody (JE64-56) [NBP3-32852] - Western blot analysis of PREB on HepG2 cell lysates with Rabbit anti-PREB antibody (NBP3-32852) at 1/500 dilution. Lysates/proteins at 10 ug/Lane. Predicted band size: 45 kDa Observed band size: 45 kDa Exposure time: 2 minutes; 10% SDS-PAGE gel. Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (NBP3-32852) at 1/500 dilution was used in 5% NFDM/TBST at room temperature for 2 hours. Goat Anti-Rabbit IgG - HRP Secondary Antibody at 1:300,000 dilution was used for 1 hour at room temperature.

Immunohistochemistry: PREB Antibody (JE64-56) [NBP3-32852] - Immunohistochemical analysis of paraffin-embedded human lymph nodes tissue with Rabbit anti-PREB antibody (NBP3-32852) at 1/400 dilution. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 2 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (NBP3-32852) at 1/400 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Background

Prolactin (PRL) expression in the pituitary is limited to specific cells. Pit-1 is a pituitary specific transcription factor that plays an important role in PRL expression, both in mature organism and during development. The PRL promoter contains numerous Pit-1 binding sites and these sites have been implicated in both basal level and kinase-mediated gene expression. The most proximal of these binding sites, termed 1P, has been shown to direct a response to numerous signals, such as cAMP and various G-proteins. A novel protein, termed PREB (prolactin regulatory element binding protein), has been recently identified that regulates PRL gene expression through the 1P site, though it contains no discernable DNA-binding motif. Recent studies suggest that PREB is encoded by a single-copy gene in both mice and humans and exhibits nuclear accumulation in pituitary cells. Evidence suggests that PREB is a novel transcription factor that assists in PRL expression whether alone, or in concert with Pit-1.
