Fibrinogen (FG) ELISA Kit for Human

Background: Fibrinogen is a soluble protein synthesized by the liver and is one of the important components in plasma. It is a key factor in the process of blood coagulation and can be converted into fibrin to help stop bleeding and repair tissue damage. Fibrinogen is involved in multiple steps of thrombus formation, including platelet aggregation at the site of injury, activation of prothrombin, and formation of thrombin. Thrombin then converts fibrinogen into insoluble fibrin, which aggregates at the site of injury to form a clot and accelerate wound healing.

Principle of the Assay: This kit was based on sandwich enzyme-linked immune-sorbent assay technology. Anti FG antibody was pre-coated onto the 96-well plate. The biotin conjugated anti FG antibody was used as the detection antibody. The standards and pilot samples were added to the wells subsequently. After incubation, unbound conjugates were removed by wash buffer. Then, biotinylated detection antibody was added to bind with FG conjugated on coated antibody. After washing off unbound conjugates, HRP-Streptavidin was added. After a third washing, TMB substrates were added to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that turned yellow after adding a stop solution. Read the O.D. absorbance at 450nm in a microplate reader. The concentration of FG in the sample was calculated by drawing a standard curve. The concentration of the target substance is proportional to the OD450 value.

Small volumes of FG elisa kit vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS765734 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Fibrinogen (FG) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing FG. The ELISA analytical biochemical technique of the MBS765734 kit is based on FG antibody-FG antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect FG antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, FG. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).
