Anti-Prostate Specific Antigen antibody [EP1588Y] (ab76113)


  • Product name
    Anti-Prostate Specific Antigen antibody [EP1588Y]
    See all Prostate Specific Antigen primary antibodies
  • Description
    Rabbit monoclonal [EP1588Y] to Prostate Specific Antigen
  • Host species
  • Specificity
    The antibody provided good results in western blot when tested in human prostate lysate. Unfortunately, when 22RV1 cell lysate was used no band was detected and inconsistent results were obtained with LNCaP cell lysate (where different lots of cell lysate were used for the test). Please contact our Scientific Support if you have any feedback and/or questions.
