ELISA Kit for Placenta Growth Factor (PLGF)

PlGF2; PGF; PGFL; Placental Growth Factor-Like; Vascular Endothelial Growth Factor-Related Protein


This assay has high sensitivity and excellent specificity for detection of Placenta Growth Factor (PLGF).
No significant cross-reactivity or interference between Placenta Growth Factor (PLGF) and analogues was observed.


Matrices listed below were spiked with certain level of recombinant Placenta Growth Factor (PLGF) and the recovery rates were calculated by comparing the measured value to the expected amount of Placenta Growth Factor (PLGF) in samples.

Matrix Recovery range (%) Average(%)
serum(n=5) 98-105 102
EDTA plasma(n=5) 92-99 95
heparin plasma(n=5) 98-105 102


Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Placenta Growth Factor (PLGF) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Placenta Growth Factor (PLGF) were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%


The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Placenta Growth Factor (PLGF) and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

Sample 1:2 1:4 1:8 1:16
serum(n=5) 87-102% 82-92% 98-105% 79-103%
EDTA plasma(n=5) 92-101% 78-96% 78-97% 84-96%
heparin plasma(n=5) 81-94% 93-101% 85-97% 90-104%


The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.
To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.
