Abcam’s PDGF BB in vitro SimpleStep ELISA® (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of PDGF-BB protein in human serum, plasma, and cell culture supernatant.
The SimpleStep ELISA® employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. TMB substrate is added and during incubation is catalyzed by HRP, generating blue coloration. This reaction is then stopped by addition of Stop Solution completing any color change from blue to yellow. Signal is generated proportionally to the amount of bound analyte and the intensity is measured at 450 nm. Optionally, instead of the endpoint reading, development of TMB can be recorded kinetically at 600 nm.
Platelet derived growth factor B chain plays an essential role in the regulation of embryonic development, cell proliferation, cell migration, survival and chemotaxis. As a homodimer it is a potent mitogen for cells of mesenchymal origin and is required for normal proliferation and recruitment of pericytes and vascular smooth muscle cells in the central nervous system, skin, lung, heart and placenta. PDGF-BB is essential for normal blood vessel development, for normal development of kidney glomeruli and in wound healing. Signaling is modulated by the formation of heterodimers with PDGF A chain to yield PDGF-AB.

Example of PDGF-BB standard curve for ab184860
Titration of Human serum with ab184860 within the working range of the assay. Background subtracted data from duplicate measurements are plotted.
Observed PDGF-BB levels in pooled donor normal Human plasma and normal Human platelet-poor plasma (PP-Plasma). Mean Human PDGF-BB values fall within expected normal reference ranges (WHO).
ab184860 was validated for assay specificity against PDGF-A protein. Background-subtracted data values (mean +/- SD) are graphed. In addition, PDGF-A was prepared at 15 ng/mL and assayed for cross reactivity. No cross reactivity or interference was observed.
Observed PDGF-BB levels in individual donor normal Human serum (n=10). Mean Human PDGF-BB is 145 pg/mL and values fall within expected normal reference ranges (WHO).
Human peripheral blood cells (1x106 cells/mL) were cultured in RPMI media supplemented with 10% fetal calf serum, 100 U/mL penicillin, and 100 µg/mL streptomycin sulfate. Cells were cultured unstimulated or stimulated with 10 µg/mL PHA. Conditioned media was harvested after 48 hours, aliquoted and assayed for endogenous PDGF-BB levels.
ab184860 has not yet been referenced specifically in any publications.
