- 实验流程
- The assay measures the ability of tPA to activate the plasminogen to plasmin in coupled or indirect assays that contain tPA, plasminogen, and a plsmin-specific synthetic substrate. The amount of plasmin produced is quantitated using a highly specific plasmin substrate releasing a yellow para-nitroaniline (pNA) chromophore. The change in absorbance of the pNA in the reaction solution at 405 nm is directly proportional to the tPA enzymatic activity.

Plasminogen: Add 1.2 ml reagent grade water. Plasmin Substrate: Add 1.1 ml reagent grade water. Standard Curve: Reconstitute the tPA Standard with 1.2 ml of reagent grade water to generate a solution of 40 IU/ml. Allow the standard to sit for 10 minutes with gentle agitation prior to making dilutions. Prepare triplicate standard points by serially diluting the standard solution (40 IU/ml) 1:4 with Assay Diluent to produce 10, 2.5, 0.625, 0.156, and 0.039 IU/ml. 2 Standard Point Dilution [tPA] (IU/ml) P1 1 part Standard (40 IU/ml) 40.000 P2 1 part P1 + 3 part Assay Diluent 10.000 P3 1 part P2 + 3 part Assay Diluent 2.500 P4 1 part P3 + 3 part Assay Diluent 0.625 P5 1 part P4 + 3 part Assay Diluent 0.156 P6 1 part P5 + 3 part Assay Diluent 0.039 P7 Assay Diluent 0.000
- 样品收集
- Plasma: Collect plasma using one-tenth volume of acidified 0.5 M sodium citrate (pH 4.0) as an anticoagulant to prevent tPA-PAI complex formation. Centrifuge samples at 3000 x g for 15 minutes.

Calculate the mean value of the duplicate or triplicate for each standard and sample. To generate a Standard Curve from the initial reaction time, plot the graph using the standard concentrations on the x-axis and the corresponding mean 405 nm absorbance or change in absorbance per minute (A/min) on the y-axis. The best-fit line can be determined by regression analysis of the linear portion of the curve. Determine the unknown sample concentration from the Standard Curve and multiply the value by the dilution factor. 3 Standard Curve 1) The curve is provided for illustration only. A standard curve should be generated each time the assay is performed.

- 背景
- Tissue-type plasminogen activator (tPA) is a 68 kDa serine protease that converts the zymogen plasminogen into the active serine protease plasmin which digests fibrin and induce the dissolution of fibrin clots. tPA is synthesized by endothelial cells in normal blood vessels and displays relatively high affinity for fibrin, suggesting that it functions predominately in physiological thrombolysis in vivo. High level of tPA is a good prognostic marker for breast cancer. tPA may minimize the formation of metastasis by preventing tumor cell adherence at sites of trauma. On the other hand, gastrointestinal cancer is accompanied by a decrease in tPA.
