The gpIIb/IIIa complex, also known as integrin αIIbβ3, is expressed by megakaryocytes and platelets. It undergoes conformational changes upon activation by substances, such as ADP, thrombin, and TXA2, which subsequently reveals a ligand binding site that is specific for fibrinogen, von Willebrand factor (vWF), fibronectin, and vitronectin. This conformational change is crucial for platelet-platelet adhesion. Ligand bound gpIIb/IIIa complex promotes platelet aggregation. This complex plays an important role in hemostasis and is a target for developing therapeutic antibodies in immune thrombocytopenia.Product Details

- The antibody was purified by affinity chromatography and conjugated with FITC under optimal conditions.
- Lot-specific (please contact technical support for concentration and total µg amount, or use our Lookup tool if you have a lot number.)
- Storage & Handling
- The antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light. Do not freeze.
FC - Quality tested
- Recommended Usage
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µl per million cells in 100 µl staining volume or 5 µl per 100 µl of whole blood.
- Excitation Laser
Blue Laser (488 nm)
- Application Notes
Additional reported applications (for the relevant formats of this clone) include: immunoprecipitation1,2, Western blotting2 and in vitro blocking of platelet aggregation2.
The PAC-1 antibody reacts with activation-induced conformational epitope of the integrin aIIbß3. PAC-1 binding to fibrinogen is pH and Ca2+ dependent, and will not bind to platelets that have been fixed. We recommend staining in buffers free of Ethylenediaminetetraacetic acid (EDTA) at a pH of 6.5 or higher. Sodium citrate may be used as an anticoagulant for blood collection3.
