Canine (dog) PAI-1 total antigen assay ELISA kit
Plasminogen activator inhibitor type 1 (PAI-1) is involved in the regulation of the blood fibrinolytic system. Increased plasma levels of PAI-1 are implicated in the impairment of fibrinolytic function and may be associated with thrombotic diseases. Levels of PAI-1 increase with age and are elevated in conditions such as normal pregnancy and sepsis. The sensitive quantitative measurement of total dog PAI-1 antigen in plasma samples is easily performed with this 96 well strip format ELISA kit. The assay measures dog PAI-1 in the 0.2-100 ng/ml range. Samples giving dog PAI-1 levels above 100 ng/ml should be diluted in blocking buffer before use. A 1:5 to 1:20 dilution for plasma is suggested for best results. It is important to ensure a platelet free preparation of plasma as platelets can release PAI-1. Dog PAI-1 will bind to the capture antibody coated on the microtiter plate. Free, latent, and complexed PAI-1 will be detected by the assay. After appropriate washing steps, biotin labeled anti-dog PAI-1 primary antibody binds to the captured protein. Excess primary antibody is washed away and bound antibody is reacted with streptavidin conjugated to HRP. Following an additional washing step, TMB substrate is used for color development at 450 nm. Color development is proportional to the concentration of dog PAI-1 in the samples. A standard calibration curve is prepared in blocking buffer using dilutions of purified dog PAI-1 and is measured along with the test samples. All reagents and standards are provided in these ELISA kits.
