Purity:  >95% by SDS-PAGE and HPLC analyses.
Biological Activity:  Data Not Available.
Physical Appearance:  Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation:  Lyophilized from a 0.2μm filtered concentrated solution in 20mM PB, pH7.4, 150mM NaCl.
Endotoxin:  Less than 1EU/μg of rHuPEDF as determined by LAL method.
Reconstitution:  We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the
 bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a
 concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and
 stored at <-20°C. Further dilutions should be made in appropriate buffered solutions.
Storage:  This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage,
 preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For
 maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to
 -70°C. Avoid repeated freeze/thaw cycles.
Usage:  This material is offered by Shanghai Corning Bio-Tech for research, laboratory or further
 evaluation purposes. NOT FOR HUMAN USE.

Human Pigment Epithelium-derived Factor
Pigment Epithelium-derived Factor (PEDF) is a noninhibitory serpin with neurotrophic, anti-angiogenic, and anti-tumorigenic
properties. It is a 50 kDa glycoprotein produced and secreted in many tissues throughout the body. A major component of the
anti-angiogenic action of PEDF is the induction of apoptosis in proliferating endothelial cells. In addition, PEDF is able to inhibit
the activity of angiogenic factors such as VEGF and FGF-2. The neuroprotective effects of PEDF are achieved through
suppression of neuronal apoptosis induced by peroxide, glutamate, or other neurotoxins. The recent identification of a lipaselinked
cell membrane receptor for PEDF (PEDF-R) that binds to PEDF with high affinity should facilitate further elucidation of
the underlying mechanisms of this pluripotent serpin. To date, PEDF-R is the only signaling receptor known to be used by a
serpin family member. The unique range of PEDF activities implicate it as a potential therapeutic agent for the treatment of
vasculature related neurodegenerative diseases such as age-related macular degeneration (AMD) and proliferative diabetic retinopathy (PDR). PEDF also has the potential to be useful in the treatment of various angiogenesis-related diseases including a
number of cancers.
