Human Pregnancy Associated Plasma Protein A (PAPPA) ELISA Kit

The Human Pregnancy-Associated Plasma Protein-A (PAPP-A) ELISA Kit is specifically designed for the accurate measurement of PAPP-A levels in human serum, plasma, and cell culture supernatants. This kit offers high sensitivity and specificity, ensuring precise and reproducible results for a variety of research applications.PAPP-A is an important protein associated with pregnancy, as it plays a key role in facilitating fetal growth and development. Abnormal levels of PAPP-A have been linked to various pregnancy complications, making it a valuable biomarker for studying pregnancy-related conditions and improving prenatal care.

With the Human PAPP-A ELISA Kit, researchers can confidently analyze PAPP-A levels in biological samples, aiding in the understanding of pregnancy physiology and pathology. This kit provides a reliable tool for advancing research in obstetrics, gynecology, and reproductive health.

Product Name:Human Pregnancy Associated Plasma Protein A (PAPPA) ELISA Kit
Product Code:HUDL02185
Size:96 Assays
Target:PAPPA
Synonyms:PAPP-A, PAPA, ASBABP2, DIPLA1, IGFBP-4ase, PAPPA1, Pappalysin 1, Insulin-Like Growth Factor Binding Protein-4 Protease, Differentially Placenta 1 Expressed Protein
Detection Method:Sandwich
Range:0.312-20ng/mL
Shelf Life:12 months
Note:For research use only
Recovery:Matrices listed below were spiked with certain level of recombinant the index and the recovery rates were calculated by comparing the measured value to the expected amount of the index in samples.
MatrixRecovery range (%)Average(%)
Serum (n=5)80-10291
EDTA plasma (n=5)81-10090
Heparin plasma (n=5)80-8984
Linearity:The linearity of the kit was assayed by testing samples spiked with appropriate concentration of the index 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) 82-96% 83-98% 81-99% 93-101%
EDTA plasma (n=5) 88-101% 86-95% 90-102% 80-93%
Heparin plasma (n=5) 80-91% 82-90% 95-104% 79-95%
Intra-assay Precision:Intra-Assay: CV <10%. 3 samples with low, middle and high level the index were tested 20 times on one plate, respectively.
Inter-assay Precision:Inter-Assay: CV <12%. 3 samples with low, middle and high level the index were tested on 3 different plates, 8 replicates in each plate.
Stability:The stability of ELISA 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 conditions. Note: To minimize unnecessary influences on the performance, operation procedures and lab conditions, especially room temperature, air humidity and incubator temperatures should be strictly regulated. It is also strongly suggested that the whole assay is performed by the same experimenter from the beginning to the end.
