Preparation and Storage
May be stored at 4 degree C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Freeze at -20 degree C. Aliquots are stable for at least 12 months at -20 degree C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
Other Notes
Small volumes of anti-Pou4f1 antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

Research Articles on Pou4f1
1. data define AR as a direct Brn-3a interactor and verify a simple interacting protein prediction methodology that is likely to be useful for many other proteins
2. Data show that Brn3a acts upstream of the Runx factors, which then repress TrkB expression to allow establishment of the non-overlapping Trk receptor profiles and correct terminally differentiated phenotypes.
3. Brn3a regulates the transition from neurogenesis to terminal differentiation and represses non-neural gene expression in the trigeminal ganglion.
4. these findings begin to define a gene regulatory pathway for habenula development in mammals, and the roles of Nurr1 and Brn3a therein.
5. Brn-3a deficiency affects the number and cell size of CGRP- and calcium-binding protein-containing neurons.
6. Loss of Brn3a leads to an increase in the ratio of bistratified to monostratified RGCs, with only modest RGC loss and little effect on central projections.
7. Brn3a represses differences in gene expression between sensory neurons generated at different axial levels, and regulates developmental gene expression; functionally similar populations of neurons are generated from different embryological substrates.
8. results suggest that co-factors binding to p73 C terminus facilitate activation on Bax but not p21 CIP1/Waf1 promoter and that Brn-3a modulates this interaction
9. Data suggest that Brn-3a and b POU factors may play an important role in the development and maintenance of critical cell types and structures within the heart, in part via developmental regulation of myocardial Hsp27 expression.
10. Data show that Pou4f1 is regionally enriched in the Brainstem (Pons and Medulla) of mouse brain.
