Solnerstotug
Based on 1 Customer Validation
Solnerstotug (SNS-101; SNA 101) is a pH-sensitive humanized IgG1κ antibody targeting VISTA. The affinity of Solnerstotug for VISTA decreases continuously with increasing pH, with KD values of 0.35 nM and 353 nM at pH 5.8 and pH 7.4, respectively. Solnerstotug reshapes the tumor microenvironment by selectively blocking the interaction of VISTA with receptors such as PSGL-1 (IC50 = 6.7 nM) in acidic environments, polarizing macrophages toward a pro-inflammatory M1-like phenotype and increasing intratumoral CD8+ T cell infiltration. Solnerstotug can be used for cancer research.

In Vitro
Solnerstotug (1-100 μg/mL; 4 h) does not induce significant cytokine secretion in human whole blood cells and only slightly induces monocyte and NK cell activation and a small amount of IL-8 release at the highest dose[2].
Solnerstotug (pH 7.4) shows low binding to human monocytes, neutrophils, NK cells, and T cells, with fold changes relative to the control of 1.2, 0.9, 0.5, and 1, respectively[2].
Solnerstotug binds human VISTA in a pH-selective manner, with KD increasing from 0.35 nM at pH 5.8 to 353 nM at pH 7.4[2].

Cell Line:circulating human whole blood cell
-
Concentration:1, 10, 100 μg/mL
-
Incubation Time:4 h
-
Result:Reduced the release of inflammatory cytokines (such as IFN-γ, IL-6, TNF-α) compared to non-pH-selective control antibodies, only significantly increased IL-8 levels at 100 μg/mL。
Activated monocytes and NK cells at 100 μg/mL without causing platelet reduction.

Immobilized VISTA/B7-H5 Protein, Human (HEK293, Fc, HY-P77879) can bind Solnerstotug. The EC50 for this effect is 81.98 ng/mL. -
Flow cytometric analysis of 1×106 Jurkat cells labelling B7-H5 (red) with Solnerstotug (HY-P991025). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. Alexa Goat Anti-Human IgG H&L (AF488) (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG1 kappa Isotype Control (HY-P99001, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
