Platelet-derived growth factor D (PDGFD) is a protein that in humans is encoded by the PDGFD gene. The protein encoded by this gene is a member of the platelet-derived growth factor family. PDGF plays a significant role in blood vessel formation, the growth of blood vessels from already-existing blood vessel tissue, mitogenesis. PDGF also plays a role in embryonic development, cell proliferation, cell migration, and angiogenesis. Besides, Macrophage Erythroblast Attacher (MAEA) has been identified as an interactor of PDGFD, thus a binding ELISA assay was conducted to detect the interaction of recombinant human PDGFD and recombinant human MAEA. Briefly, PDGFD were diluted serially in PBS, with 0.01% BSA (pH 7.4). Duplicate samples of 100μL were then transferred to MAEA-coated microtiter wells and incubated for 2h at 37℃. Wells were washed with PBST and incubated for 1h with anti-PDGFD pAb, then aspirated and washed 3 times. After incubation with HRP labelled secondary antibody, wells were aspirated and washed 3 times. With the addition of substrate solution, wells were
incubated 15-25 minutes at 37℃. Finally, add 50µL stop solution to the wells and read at 450nm immediately. The binding activity of PDGFD and MAEA was shown in Figure 1, and this effect was in a dose dependent manner.
