PLGF ELISA Kit

INTENDED USE

Human PLGF ELISA kit is a reliable quantitative procedure for measuring placenta growth factor (PGF, PLGF, PIGF) in human serum samples. This assay has a minimum sensitivity detection limit of < 1.062 pg/ml.

BACKGROUND

The PLGF protein is a recently identified placenta growth factor (PGF, PIGF) which is a 149 amino acid in length and displays over 53% homology with the platelet-derived growth factor-like region of the human VEGF. The human PLGF gene is found to be mapped to 14q24-q31 and the N-glycosylated PLGF protein can be secreted into the medium where it can function as a dimer. PLGF is a growth factor that is active in angiogenesis and endothelial cell growth where it functions in stimulating their proliferation and migration. It has the ability to bind to receptor of VEGFR-1/FLT1, it regulates the intra- and intermolecular cross talk between FLK12 and VEGF receptor tyrosine kinases FLT1.  There is also evidence that it can stimulate collateral growth and angiogenesis in limb and ischemic heart with comparable efficiency to VEGF3.

The following human PLGF ELISA kit can be used for many different clinical applications. Angiogenesis and vascular transformation are two of the most important processes during the normal development of the placenta. Intrauterine growth retardation and pre-eclamptic pregnancies can occur as a result of abnormal angiogenesis and vascular transformation.

PLGF ELISA KIT CONTENT

All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

SENSITIVITY

The minimum sensitivity detection limit of placenta growth factor (PGF, PLGF, PIGF) using current human PLGF ELISA kit was approximately < 1.062 pg/ml. The dynamic range for this assay is 1.06 – 1000.0 pg/ml.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
