Material not included: Microplate Reader capable of reading absorbance at 450nm. Incubator. Automated plate washer (optional). Pipettes and pipette tips capable of precisely dispensing 0.5 μL through 1 mL volumes of aqueous solutions. Multichannel pipettes are recommended for large amount of samples. Deionized or distilled water. 500 mL graduated cylinders. Test tubes for dilution.

Application Details

Application Notes: Before using Kit, spin tubes and bring down all components to bottom of tube. Duplicate well assay was recommended for both standard and sample testing.

Sample Volume: 100 μL

Plate: Pre-coated

Protocol: ELISA Kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. An antibody has been precoated onto 96-well plates. Standards and test samples are added to the wells, a biotinylated detection antibody specific for target is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the target amount in sample captured in plate.

Target Details for PLGF

Target: PLGF (PGF) (Placenta Growth Factor (PGF))

Alternative Name: PGF

Background:

Background: The protein, also called PGF, is 149 amino acids long and shares 53 % identity with the platelet-derived growth factor-like region of human VPF. And the N-glycosylated PLGF protein is secreted into the medium and that it functions as a dimer1. The PLGF gene is mapped to 14q24-q31. There are 3 isoforms of PGF, designated PGF1, PGF2, and PGF3. Only PGF2 is able to bind heparin. Additionally, PGF regulates inter- and intramolecular cross-talk between the VEGF receptor tyrosine kinases FLT1 and FLK12. It also can stimulate angiogenesis and collateral growth in ischemic heart and limb with at least a comparable efficiency to VEGF3.
