General notes
According to Swissprot P49763; PLGF exists in three isoforms PLGF 1, 2 and 3. The N-terminal immunogen sequence of ab9542 is present in all isoforms so extra bands might be observed near the band of interest.

Applications
The Abpromise guarantee
Our Abpromise guarantee covers the use of ab9542 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Application | Abreviews | Notes |
---|---|---|
WB | (1) |
Use a concentration of 1 - 4 µg/ml.
It will detect 25 - 50 ng/lane of recombinant human PLGF-1 (17-18 kDa) and PLGF-2 (22-23 kDa) under reducing conditions. Dimers are detected at higher protein amounts/lane. |
ICC/IF |
Use a concentration of 1 µg/ml.

Target
-
Function
Growth factor active in angiogenesis and endothelial cell growth, stimulating their proliferation and migration. It binds to the receptor FLT1/VEGFR-1. Isoform PlGF-2 binds NRP1/neuropilin-1 and NRP2/neuropilin-2 in a heparin-dependent manner. -
Tissue specificity
While the three isoforms are present in most placental tissues, PlGF-2 is specific to early (8 week) placenta and only PlGF-1 is found in the colon and mammary carcinomas. -
Sequence similarities
Belongs to the PDGF/VEGF growth factor family. -
Domain
Isoform PlGF-2 contains a basic insert which acts as a cell retention signal. -
Post-translational
modificationsN-glycosylated. -
Cellular localization
Secreted. The three isoforms are secreted but PlGF-2 appears to remain cell attached unless released by heparin. - Information by UniProt

ICC/IF image of ab9542 stained HepG2 (human liver hepatocellular carcinoma cell line) cells. The cells were fixed in 4% formaldehyde for 10 minutes and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1 hour to permeabilize the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab9542, 1 µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1 hour. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1 hour. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43 µM.
