Human Protein Z Dependent Protease Inhibitor (ZPI) ELISA Kit
The Human Protein Z-dependent Protease Inhibitor (ZPI) ELISA Kit is a cutting-edge tool for the accurate quantification of ZPI levels in human biological samples. This kit is specifically designed to provide researchers with highly sensitive and specific results, ensuring robust and reliable data for a variety of research applications.ZPI is a key inhibitor of blood coagulation factors, playing a crucial role in maintaining the balance between procoagulant and anticoagulant pathways. Dysregulation of ZPI has been implicated in various thrombotic disorders, making it a valuable biomarker for studying blood clotting disorders and developing targeted interventions.
With its advanced technology and user-friendly protocol, the Human Protein Z-dependent Protease Inhibitor (ZPI) ELISA Kit is a valuable asset for researchers looking to explore the role of ZPI in health and disease. Whether investigating cardiovascular conditions, hemostasis disorders, or other related research areas, this kit offers unparalleled precision and accuracy in ZPI detection.

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.

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.
