重组人色素上皮细胞衍生因子 HEK(Human PEDF HEK)

PEDF Human, HEK
Pigment Epithelium-Derived Factor Human Recombinant, HEK
Catalog No. CYT-553

Synonyms:
Pigment epithelium-derived factor, PEDF, Serpin-F1, SerpinF1, EPC-1, EPC1, PIG35.

Introduction:
PEDF is a neurotrophic protein that induces extensive neuronal differentiation in retinoblastoma cells. SerpinF1 is a potent inhibitor of angiogenesis. EPC1 doesn’t undergo the stressed to relaxed conformation transition characteristic as of the active serpins since it exhibits no serine protease inhibitory activity.
Aqueous humour level of asymmetric dimethylarginine is correlated with PEDF in humans. ADMA and PEDF levels are increased in response to inflammation in uveitis.
Lack of PEDF expression is a potent factor for the enhancement of tumor growth and angiogenesis in breast cancer.
PEDF & VEGF genes contribute to the development of diabetic retinopathy.
PEDF and VEGF structural changes in blood vessel wall play an important role in the pathophysiology of PD patients.
PEDF-overexpressing tumors exhibited reduced intratumoral angiogenesis.
SerpinF1 is a new promising approach for the treatment of osteosarcoma.
Levels of the natural ocular anti-angiogenic factor SentrinF1 (PEDF) is associated with proliferative retinopathy.
VEGF secreted by retinal pigment epithelial cells upregulates PEDF expression via VEGFR-1 in an autocrine manner.
Sentrin-F1 concentration in the aqueous humor of diabetic patients predicts who will develop progression of retinopathy.
PEDF blocks angiogenic effects of leptin through its anti-oxidative properties.

Description:
PEDF Human Recombinant produced in HEK cells is a single, glycosylated, polypeptide chain containing 410 amino acids and having a molecular mass of 45.6 kDa.
The Human Sentrin-F1 is fused to FLAG tag at N-Terminus.
The Human PEDF is purified by proprietary chromatographic techniques.
