PBP antibody

I first tried the PBP antibody (NB110-93495) in June of 2010 and it worked well. I picked this antibody because it had been tested in rat tissue, so I was confident it would work for my rat samples. I stored the PBP antibody in 20ul aliquots after it arrived then stored it at -20C and used it over a 3 month period. I ran a Western blot with 15ug of a RIPA whole cell lystate from WKPT cells a rat kidney immortalized cell line derived from the S1 proximal tubule segment.
