• Product name
  • Description
    Rabbit polyclonal to PEDF
  • Host species
  • Specificity
    Recognizes PEDF at 50kDa. Additional bands were detected at 66 and 76kDa, which were competed away by immunogen. These bands may be post translationally modified forms.
  • Tested applications
    Suitable for: WBmore details
  • Species reactivity
    Reacts with: Mouse, Human
  • Immunogen

    His tagged fusion protein corresponding to full length human PEDF (Pigment Epithelial Derived Factor) expressed in baby hamster kidney cells.

  • Positive control
    • RIPA lysates from Y79 cells.
  • General notes
    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.



Our Abpromise guarantee covers the use of ab14993 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 0.5 - 2 µg/ml. Detects a band of approximately 50 kDa (predicted molecular weight: 50 kDa).


  • Function
    Neurotrophic protein; induces extensive neuronal differentiation in retinoblastoma cells. Potent inhibitor of angiogenesis. As it does not undergo the S (stressed) to R (relaxed) conformational transition characteristic of active serpins, it exhibits no serine protease inhibitory activity.
  • Tissue specificity
    Retinal pigment epithelial cells and blood plasma.
  • Sequence similarities
    Belongs to the serpin family.
  • Developmental stage
    Expressed in quiescent cells.
  • Domain
    The N-terminal (AA 44-121) exhibits neurite outgrowth-inducing activity. The C-terminal exposed loop (AA 382-418) is essential for serpin activity.
  • Post-translational
    The N-terminus is blocked. Extracellular phosphorylation enhances antiangiogenic activity.
    N- and O-glycosylated. O-glycosylated with a core 1 or possibly core 8 glycan.
  • Cellular localization
    Secreted. Melanosome. Enriched in stage I melanosomes.
