APPLICATION

Application Note

WB: Use at a concentration of 0.5 - 2 μg/ml. Detects a band of approximately 50 kDa (predicted molecular weight: 50 kDa). 40μg of Y79 cell lysate was resolved by electrophoresis, transferred to nitrocellulose and probed with anti PEDF (1μg/ml). Proteins were visualized using a goat anti rabbit secondary antibody conjugated to HRP and a chemiluminescence detection system. Optimal dilutions/concentrations should be determined by the end user.

Calculated MW

46 kDa. ( Note )

Positive Control

RIPA lysates from Y79 cells

Specificity/Sensitivity

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.

Background

Pigment epithelium derived factor, originally identified in conditioned medium of cultured human fetal retinal pigment epithelial (RPE) cells, is a neurotrophic protein that induces extensive neuronal differentiation in human Y79 retinoblastoma cells, a neoplastic counterpart of normal retinoblasts. It has been suggested that PEDF is synthesized by RPE cells and secreted into the retina interphotoreceptor matrix where it may influence development/differentiation of the neural retina. PEDF is a 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. The PEDF gene is a member of the serpin gene family. Serpins are a group of serine protease inhibitors, some of which have also been reported to exhibit neurotrophic activity.
