Mouse Anti-BTN3A1 Recombinant Antibody (clone 20.1) (CAT#: PABL-414)
Recombinant Mouse Antibody (20.1) is capable of binding to BTN3A1. This agonist antibody, 20.1, binds to the extracellular domain of BTN3A molecules and induces Vγ9Vδ2 activation with similar kinetics and potency as with addition of PiPs.

ELISA
Figure 1 HLA haplo-identical HeLa-L and HeLa-M cells vary in their ability to present phosphoantigens to Vγ9Vδ2 T cells.
Activation of Vγ9/Vδ2 T cells detected by ELISA for IFN-γ using a concentration gradient of HMB-PP, agonist antibody CD277 20.1 and T cells expanded from two separate donors. Activation was induced by pretreatment of HeLa cells using anti-BTN3A monoclonal antibody 20.1 for 30 min. Graphs show mean and SD from n = 2 and are representative of two independent measurements.

Girard, Pauline, et al. "Dysfunctional BTN3A together with deregulated immune checkpoints and type I/II IFN dictate defective interplay between pDCs and γδ T cells in melanoma patients, which impacts clinical outcomes." Clinical & Translational Immunology 10.11 (2021): e1329. https://doi.org/10.1002/cti2.1329
This study investigates the dysfunctional BTN3A and its interaction with deregulated immune checkpoints and type I/II interferons in the context of melanoma. The research focuses on the roles of plasmacytoid dendritic cells (pDCs) and gamma-delta (γδ) T cells, examining their phenotypic and functional interactions in both the blood and tumor microenvironment of melanoma patients. The study highlights severe alterations in the bidirectional cross-talk between pDCs and γδ T cells in melanoma, noting that while healthy pDCs can drive potent activation of γδ T cells, those from melanoma patients exhibit impaired functionality.
Creative Biolabs provided critical reagents for this study, specifically anti-BTN3A agonist antibody (clone 20.1, Cat# PABL-414) and anti-BTN3A blocking antibody (clone 103.2, Cat# PABL-415). These antibodies were used to assess the functionality of BTN3A on γδ T cells and pDCs within PBMCs and tumor infiltrates. The use of these antibodies was essential in revealing the potential functional impairment of BTN3A in melanoma patients, thereby providing insights into the therapeutic targeting of BTN3A to improve immune responses in cancer therapy.
