The Quantikine Mouse PlGF-2 Immunoassay is a 4.5 hour solid phase ELISA designed to measure mouse PlGF-2 levels in cell culture supernates, serum, and plasma. It contains Sf 21-expressed recombinant mouse PlGF-2 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural mouse PlGF-2 showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring mouse PlGF-2.
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.
Cell Culture Supernates, Serum, EDTA Plasma
The recovery of mouse PlGF-2 spiked to three levels throughout the range of the assay in various matrices was evaluated.
Average % Recovery
Cell Culture Supernates (n=6)
EDTA Plasma (n=6)
To assess the linearity of the assay, six samples containing and/or spiked with high concentrations of mouse PlGF-2 in each matrix were diluted with Calibrator Diluent and then assayed.
Preparation and Storage
Store the unopened product at 2 - 8 °C. Do not use past expiration date.
Placenta growth factor (PlGF) is a member of the vascular endothelial growth factor (VEGF) family of growth factors. PlGF and VEGF share primary structural as well as limited amino acid sequence homology with the A and B chains of PDGF. All eight cysteine residues involved in intra-and inter-chain disulfides are conserved among these growth factors. As a result of alternative splicing, three PlGF RNAs encoding monomeric human PlGF-1, PlGF-2 and PlGF-3 isoform precursors containing 149, 179 and 219 amino acid residues, respectively, have been described.
In normal mouse tissues, only one mouse PlGF mRNA encoding the equivalent of human PlGF-2 has been identified. Mouse PlGF-2 encodes a 158 amino acid residue precursor protein. Mouse PlGF-2 shares 65% amino acid identity with human PlGF-2. The gene for PlGF has been mapped to mouse chromosome 12 and human chromosome 14.
