Used for the quantitative measurement of Placenta Growth Factor-1 (PIGF-1) in human serum, plasma, and other biological fluids. This ELISA kit is widely applied in clinical research to study angiogenesis, preeclampsia, and various cancers where PIGF-1 plays a role in blood vessel formation and disease progression. It enables early detection and monitoring of placental disorders during pregnancy and supports oncology research by assessing tumor growth and response to anti-angiogenic therapies. The assay is highly sensitive and specific, allowing accurate determination of PIGF-1 levels in small sample volumes.
