Description
Human F5 (Coagulation Factor V/Plasma Factor V) ELISA Kit
The Human F5 Coagulation Factor V Plasma Factor V ELISA Kit is a powerful tool for measuring levels of Factor V in human plasma samples. This kit offers high sensitivity and specificity, providing reliable and consistent results for a variety of research applications.Factor V is a key player in the blood coagulation process, essential for the formation of blood clots and maintaining hemostasis. Dysregulation of Factor V can lead to conditions such as thrombosis or bleeding disorders, making it a valuable biomarker for monitoring and studying these health conditions.
Whether investigating hemostasis, thrombosis, or other related disorders, the Human F5 Coagulation Factor V Plasma Factor V ELISA Kit provides accurate and precise measurement of Factor V levels in human plasma samples, aiding in the advancement of research and potential therapeutic interventions.

This ELISA kit uses Sandwich-ELISA as the method. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human F5. Standards or samples are added to the appropriate micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human F5 and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well successively and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human F5, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by adding Stop Solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human F5. The concentration of Human F5 in samples can be calculated by comparing the OD of the samples to the standard curve.
| UniProt Protein Function: | factor V: Central regulator of hemostasis. It serves as a critical cofactor for the prothrombinase activity of factor Xa that results in the activation of prothrombin to thrombin. Defects in F5 are the cause of factor V deficiency (FA5D); also known as Owren parahemophilia. It is an hemorrhagic diastesis. Defects in F5 are the cause of thrombophilia due to activated protein C resistance (THPH2). THPH2 is a hemostatic disorder due to defective degradation of factor Va by activated protein C. It is characterized by a poor anticoagulant response to activated protein C resulting in tendency to thrombosis. Defects in F5 are a cause of susceptibility to Budd- Chiari syndrome (BDCHS). A syndrome caused by obstruction of hepatic venous outflow involving either the hepatic veins or the terminal segment of the inferior vena cava. Obstructions are generally caused by thrombosis and lead to hepatic congestion and ischemic necrosis. Clinical manifestations observed in the majority of patients include hepatomegaly, right upper quadrant pain and abdominal ascites. Budd-Chiari syndrome is associated with a combination of disease states including primary myeloproliferative syndromes and thrombophilia due to factor V Leiden, protein C deficiency and antithrombin III deficiency. Budd-Chiari syndrome is a rare but typical complication in patients with polycythemia vera. Defects in F5 may be a cause of susceptibility to ischemic stroke (ISCHSTR); also known as cerebrovascular accident or cerebral infarction. A stroke is an acute neurologic event leading to death of neural tissue of the brain and resulting in loss of motor, sensory and/or cognitive function. Ischemic strokes, resulting from vascular occlusion, is considered to be a highly complex disease consisting of a group of heterogeneous disorders with multiple genetic and environmental risk factors. Defects in F5 are associated with susceptibility to pregnancy loss, recurrent, type 1 (RPRGL1). RPRGL1 is a common complication of pregnancy, resulting in spontaneous abortion before the fetus has reached viability. The term includes all miscarriages from the time of conception until 24 weeks of gestation. Recurrent pregnancy loss is defined as 3 or more consecutive spontaneous abortions. Belongs to the multicopper oxidase family. |

| NCBI Summary: | This gene encodes an essential cofactor of the blood coagulation cascade. This factor circulates in plasma, and is converted to the active form by the release of the activation peptide by thrombin during coagulation. This generates a heavy chain and a light chain which are held together by calcium ions. The activated protein is a cofactor that participates with activated coagulation factor X to activate prothrombin to thrombin. Defects in this gene result in either an autosomal recessive hemorrhagic diathesis or an autosomal dominant form of thrombophilia, which is known as activated protein C resistance.

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e. g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.
