sequence length :

418

purity :

>95% by SDS-PAGE and HPLC analyses.

form :

Lyophilized from a 0.2mm filtered concentrated (1.0mg/ml) solution in 20mM PB, pH7.4, 150mM NaCl. Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.

storage stability :

This lyophilized preparation is stable at 2-8 degree C, but should be kept at -20 degree C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 degree C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 degree C to -70 degree C. Avoid repeated freeze/thaw cycles.

Endotoxin Level: Less than 1EU/mg of rHuPEDF as determined by LAL method.

products description :

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 lipase-linked 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 agerelated 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.

ncbi summary :

The protein encoded by this gene is a member of the serpin family, although it does not display the serine protease inhibitory activity shown by many of the other serpin family members. The encoded protein is secreted and strongly inhibits angiogenesis. In addition, this protein is a neurotrophic factor involved in neuronal differentiation in retinoblastoma cells.[provided by RefSeq, Mar 2011]

uniprot summary :

PEDF: a secreted neurotrophic protein that 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. The N-terminal (AA 44-121) exhibits neurite outgrowth-inducing activity. The C-terminal exposed loop (AA 382-418) is essential for serpin activity. Extracellular phosphorylation enhances antiangiogenic activity. Protein type: Secreted; Secreted, signal peptide; Inhibitor. Chromosomal Location of Human Ortholog: 17p13.3. Cellular Component: axon hillock; extracellular matrix; extracellular space; perinuclear region of cytoplasm; melanosome; extracellular region; basement membrane. Molecular Function: serine-type endopeptidase inhibitor activity. Biological Process: cell proliferation; negative regulation of angiogenesis; positive regulation of neurogenesis; ovulation cycle; short-term memory; retina development in camera-type eye; multicellular organismal development; negative regulation of inflammatory response; response to arsenic; response to acidity; kidney development; aging. Disease: Osteogenesis Imperfecta, Type Vi
