General description
Introduction
Pigment Epithelium-Derived Factor (PEDF) was first identified as a factor secreted by primary retinal pigment epithelial (RPE) cells that promotes the survival of neurons in vitro and in vivo. Molecular characterization of PEDF shows it to be a 50 kDa member of the serpin family of protease inhibitors1. A second mode of action of PEDF was identified with the demonstration that PEDF induces apoptosis of microvascular endothelial cells, a property that maintains the avascular nature of the retina2. As a number of ophthalmologic disorders are characterized by dysregulation of the retinal innervation and microvasculature, PEDF serves as an important regulator of human eye disease3. In addition, PEDF appears to have multifunctional antitumor activity in a neuroblastoma model, as Schwann cell-derived PEDF induces a differentiated, less malignant phenotype in neuroblastoma cells, promotes further growth and survival of Schwann cells, and inhibits angiogenesis4.
ChemiKine Pigment Epithelium-Derived Factor (PEDF) kit is a sandwich stripwell-type enzyme immunoassay (EIA), which measures PEDF. The kit will measure PEDF of vitreous fluid of human origin.
Test Principle
With the ChemiKine PEDF assay system, a mouse monoclonal antibody generated against human PEDF is coated onto a microplate and is used to capture PEDF from a sample. A second, biotinylated PEDF-specific mouse monoclonal antibody detects the captured PEDF. Peroxidase-labeled streptavidin detects the biotinylated mouse monoclonal antibody. After addition of the substrate and stop solution the amount of PEDF is determined. The standard curve demonstrates a direct relationship between Optical Density (OD) and PEDF concentration: i.e., the higher the OD the higher the PEDF concentration in the sample.

Application
ChemiKine PEDF kit is designed to measure the amount of PEDF in cell culture supernatants, tissue homogenates and biological fluid (vitreous, serum, plasma, and serum-free) samples of human origin. There are enough reagents included in this kit for one 96-well immunoassay plate. Running duplicate wells for samples and standards is recommended.

Storage and Stability
Maintain the unopened kit at 2-8°C until expiration date indicated on the label. After opening the kit maintain each component at 2-8°C until expiration date indicated on the label. After reconstitution, maintain the PEDF Standard at -20ºC for up to 30 days. The standard may be frozen and thawed three times without loss of immunoreactivity. Do not store reconstituted standard at 4ºC, as loss of immunoreactivity will result.
Precautions
· Wash Buffer and Assay Diluent contain thimerosal. Thimerosal is highly toxic by inhalation, contact with skin or if swallowed. Thimerosal is a possible mutagen and should be handled accordingly.
· The instructions provided have been designed to optimize the kit′s performance. Deviation from the instructions may result in suboptimal performance of the kit and the failure to produce accurate data.
