Human Von Willebrand Factor (VWF) ELISA Kit

SKU : BHE13702262

Von Willebrand factor (vWF) is a blood glycoprotein involved in hemostasis. It is deficient or defective in von Willebrand disease and is involved in a large number of other diseases, including thrombotic thrombocytopenic purpura, Heyde's syndrome, and possibly hemolytic-uremic syndrome.
It is a large multimeric glycoprotein present in blood plasma and produced constitutively in endothelium (in the Weibel-Palade bodies), megakaryocytes (alpha-granules of platelets), and subendothelial connective tissue.
Besides, it is not an enzyme and therefore has no catalytic activity. Its primary function is binding to other proteins, particularly Factor VIII and it is important in platelet adhesion to wound sites.

Background	Von Willebrand factor (vWF) is a blood glycoprotein involved in hemostasis. It is deficient or defective in von Willebrand disease and is involved in a large number of other diseases, including thrombotic thrombocytopenic purpura, Heyde's syndrome, and possibly hemolytic-uremic syndrome. It is a large multimeric glycoprotein present in blood plasma and produced constitutively in endothelium (in the Weibel-Palade bodies), megakaryocytes (alpha-granules of platelets), and subendothelial connective tissue. Besides, it is not an enzyme and therefore has no catalytic activity. Its primary function is binding to other proteins, particularly Factor VIII and it is important in platelet adhesion to wound sites.
Notes	This Human Von Willebrand Factor (VWF) ELISA Kit employs a two-site sandwich ELISA to quantitate VWF in samples. An antibody specific for VWF has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyVWF present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for VWF is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of VWF bound in the initial step. The color development is stopped and the intensity of the color is measured.
Usage Notes	Do not mix components from different kit lots or use reagents beyond the kit expiration date. Allow all reagents to warm to room temperature for at least 30 minutes before opening. Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination. Unused wells must be kept desiccated at 4 °C in the sealed bag provided. Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes. It is recommended that all samples and standards be assayed in duplicate or triplicate.
