Key features and details | |
Cat. No. | MABL-1719 |
Name | Anti-Glycoprotein GPIIb/IIIa complex mAbs |
Clone No. | AFD-314.3 |
From | Recombinant Antibody |
Isotype | Engineer antibody |
Application | crystallization, in vitro, FC |
Species Reactivity | Human |
Basic Information | |
Specificity | The antibody recognizes the N terminus of the GPIIb beta propeller domain only when soluble quinine is present. |
Alternative Name | Integrin beta-3; Platelet membrane glycoprotein IIIa; GPIIIa; CD61; integrin αIIbβ3 |
UniProt | P05106 |
Immunogen | The original antibody was generated by immunizing BALB/c mice with a mixture of quinine- linked GPIIb/IIIa, unlinked GPIIb/IIIa, and soluble quinine. |
Application Notes | The antibody reacted with normal human platelets in the presence of quinine, as shown by flow cytometry. The reactions of the antibody with CHO cells expressing all-human GPIIb/IIIa (H/H), all-rat GPIIb/IIIa (R/R), or human/rat mixed GPIIb/IIIa integrins (H/R, R/H) were studied by flow cytometry.Quinine dependent antibody binding occurred with constructs H/H and H/R, but not with R/R or R/H (Bougie et al., 2009; PMID: 18948570). The crystal structures of the Fab fragment and its complex with quinine were determined. Quinine induced structural modifications of the Fab fragment; the authors propose that quinine remodels the Fab paratope and enables binding to the platelet GPIIb/IIIa. The monovalent KD values for quinine binding to the IgG fragment measured was 24 nM (Zhu et al., 2015; PMID: 26282540). |
