Blocking - Blocking peptide for Anti-PLGF antibody (ab83906)
Purity70 - 90% by HPLC.
- First try to dissolve a small amount of peptide in either water or buffer. The more charged residues on a peptide, the more soluble it is in aqueous solutions. - If the peptide doesn’t dissolve try an organic solvent e.g. DMSO, then dilute using water or buffer. - Consider that any solvent used must be compatible with your assay. If a peptide does not dissolve and you need to recover it, lyophilise to remove the solvent. - Gentle warming and sonication can effectively aid peptide solubilisation. If the solution is cloudy or has gelled the peptide may be in suspension rather than solubilised. - Peptides containing cysteine are easily oxidised, so should be prepared in solution just prior to use.

Placenta growth factor
Placental growth factor
Placental growth factor, vascular endothelial growth factor related protein
FunctionGrowth 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 specificityWhile 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 similaritiesBelongs to the PDGF/VEGF growth factor family.
DomainIsoform PlGF-2 contains a basic insert which acts as a cell retention signal.
Cellular localizationSecreted. The three isoforms are secreted but PlGF-2 appears to remain cell attached unless released by heparin.
