Fibrinogen is synthesized by the liver and is one of the most abundant proteins in plasma. It has two identical subunits of three polypeptide chains (alpha, beta and gamma). In the coagulation process, fibrinogen is cleaved by thrombin to form the fibrin clot. Then the clot is dissolved through plasmin cleavage of fibrin and forms D-dimer. D-dimer is an important cardiovascular biomarker. It is widely used in diagnosis to exclude deep vein thrombosis (DVT) and pulmonary embolism. Its concentration is also increased after surgery, during pregnancy, and in cancer.\u003cbr\u003e\nAlphaLISA technology allows the detection of molecules of interest in a no-wash, highly sensitive, quantitative assay. In an AlphaLISA assay, a biotinylated anti-analyte antibody binds to the Streptavidin-coated Donor beads while another anti-analyte antibody is conjugated to AlphaLISA Acceptor beads. In the presence of the analyte, the beads come into close proximity. The excitation of the Donor beads causes the release of singlet oxygen molecules that triggers a cascade of energy transfer in the Acceptor beads, resulting in a sharp peak of light emission at 615 nm.\u003cbr\u003e\nHow it works\u003cbr\u003e\nPrinciple of the AlphaLISA assay\u003c\/p\u003e\n\n\n    \u003cp\u003eThe AlphaLISA assay is based on an AlphaLISA sandwich immunoassay involving a biotinylated anti-analyte antibody bound to Streptavidin-coated AlphaLISA Donor beads and an anti-analyte antibody conjugated to AlphaLISA Acceptor beads. Both antibodies are directed against the analyte of interest. In the presence of the target, both antibodies bind to analyte and the beads come into proximity. The excitation of the Donor beads provokes the release of singlet oxygen molecules that triggers a cascade of energy transfer within the Acceptor beads, resulting in emission with λmax at 615 nm. The intensity of the signal is directly proportional to the concentration of analyte present in the sample.\u003c\/p\u003e\n\n\n\n  \u003cbr\u003e\n        \n\n\n\t\u003cbr\u003e\n  \u003cbr\u003e\n        \u003cbr\u003e\n  \n\n      \u003cbr\u003e\n  \u003cbr\u003e\n  \u003cbr\u003e\n    \u003cbr\u003e\n      \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n      \u003cbr\u003e\n    \n\n    \u003cbr\u003e\n      \n\n      \u003cbr\u003e\n        \n\n      \u003cbr\u003e\n    \n\n  \n\n\n\n\n\n    \u003cp\u003e \u003c\/p\u003e\n\n\n\n\n            \u003cp\u003eProtocol of the AlphaLISA assay\u003c\/p\u003e\u003cbr\u003e\n        \n\n            \u003cp\u003eThe AlphaLISA assay can be run in a 96- or 384-well detection plate (50 µL final). As described here, samples or standards are dispensed directly into the assay plate for the detection of the analyte of interest by AlphaLISA reagents. No washing steps are needed. The protocol can be further miniaturized or upscaled by simply resizing each addition volume proportionally. \u003cbr\u003e\nApplication-Protein Quantification\u003cbr\u003e\nAutomation Compatible-Yes\u003cbr\u003e\nBrand-AlphaLISA\u003cbr\u003e\nDetection Modality-Alpha\u003cbr\u003e\nDynamic Range-41.3 - 1,000,000 pg\/mL\u003cbr\u003e\nLimit of Detection-41.3 pg\/mL\u003cbr\u003e\nProduct Group-Kit\u003cbr\u003e\nSample Volume-5 µL\u003cbr\u003e\nShipping Conditions-Shipped in Blue Ice\u003cbr\u003e\nTarget-D-dimer\u003cbr\u003e\nTarget Class-Biomarkers\u003cbr\u003e\nTarget Species-Human\u003cbr\u003e\nTechnology-Alpha\u003cbr\u003e\nTherapeutic Area-Cardiovascular\u003cbr\u003e\nUnit Size-5,000 assay points\u003c\/p\u003e","brand":"Revvity","offers":[{"title":"Default Title","offer_id":46774530867369,"sku":"AL290F","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/revvity-al290f","provider":"Iright","version":"1.0","type":"link"}
