Notes

Abcam's Protein Z Human in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Protein Z in plasma, serum, urine, milk, and cell culture supernatants.

A Protein Z specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently a Protein Z specific biotinylated detection antibody is added and then followed by washing with wash buffer. Streptavidin-Peroxidase Conjugate is added and unbound conjugates are washed away with wash buffer. TMB is then used to visualize Streptavidin-Peroxidase enzymatic reaction. TMB is catalyzed by Streptavidin-Peroxidase to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is directly proportional to the amount of Protein Z captured in plate.

The entire kit may be stored at -20°C for long term storage before reconstitution - Avoid repeated freeze-thaw cycles.

Activity summary

Protein Z also known as PZ is a vitamin K-dependent plasma protein with a molecular mass of approximately 62 kDa. It is primarily expressed in the liver and circulates in the blood. This protein plays a mechanical role in the coagulation system by interacting with the protein Z-dependent protease inhibitor which downregulates blood coagulation contributing to hemostasis. Protein Z is different from other coagulation proteins due to its lack of enzymatic activity but impacts the regulation of thrombin formation.

Biological function summary

Protein Z serves as a significant factor in the coagulation cascade being a part of the protein C pathway complex. Although it lacks enzymatic action Protein Z interacts with other proteins such as Factor Xa and Protein Z-dependent protease inhibitor to exert its effects. Its involvement helps modulate clot formation and stabilize the coagulation process impacting blood flow regulation.

Pathways

Protein Z is intricately linked to the coagulation and thrombosis pathways. It associates with proteins including Factor Xa and Protein C. Protein Z assists in regulating thrombin generation by inhibiting excess coagulation maintaining a balance within the hemostatic system. This interaction ensures the rapid and effective stopping of blood flow when required while preventing unwarranted thrombosis a critical aspect of circulatory system maintenance.

Associated diseases and disorders

Protein Z levels link to thrombosis and hemorrhagic disorders. Abnormalities in Protein Z levels have connections with deep vein thrombosis due to its role in regulating coagulation balance. The protein Z-dependent protease inhibitor's association highlights its significance in clot formation and thrombosis prevention. Additionally deficiencies in Protein Z have connections with bleeding disorders emphasizing the protein's role in maintaining a balanced coagulation process essential for preventing excessive bleeding or clotting.
