Spartalizumab
Based on 1 Customer Validation
Spartalizumab is a humanized PD-1 IgG4 monoclonal antibody, with a Kd of 0.83 nM for human PD-1 and a Kd of 0.93 nM for cynomolgus monkey PD-1. Spartalizumab binds to PD-1 and blocks its interaction with the ligands PD-L1 and PD-L2. Spartalizumab induces increased IFNγ release. Spartalizumab can be used in the research of anaplastic thyroid carcinoma (ATC) and neuroendocrine neoplasms (NENs).

In Vitro
Spartalizumab binds to human and cynomolgus monkey PD-1 with mean Kd values of 0.83 nM and 0.93 nM, respectively, and does not bind to mouse PD-1[1].
Spartalizumab (incubated at 4°C for 4 h) inhibits the binding of PD-1 to PD-L1 and PD-L2 in PD-1-expressing murine 300.19 cells, with IC50 values of 0.9 nM and 1.3 nM, respectively[1].
Spartalizumab induces a concentration-dependent increase in IFNγ release in mixed lymphocyte reaction assays[1].

Immobilized PD-1 Protein, Human can bind Spartalizumab. The EC50 for this effect is 14.84 ng/mL. -
Flow cytometric analysis of 1X106 10 ng/mL PMA and 1 μg/mL Ionomycin co-stimulated Jurkat cells(24h) with Spartalizumab (HY-P9972, red). Cells were fixed with 4% paraformaldehyde. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. Alexa Fluor 488-conjugated AffiniPure Goat Anti-Human IgG H&L (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG4 kappa (HY-P99003, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).

Research Protocol for Endocrine Diseases
Endocrine diseases often arise from disrupted hormone production, hormone signaling, or target-tissue responsiveness; for diabetes-focused endocrine disease models, insulin signaling regulates glucose uptake, hepatic glucose output, lipid metabolism, and β-cell compensation. Type 2 diabetes develops through interacting defects in insulin resistance, β-cell dysfunction, adipose inflammation, hepatic glucose overproduction, altered incretin signaling, and ectopic lipid metabolism. A major unresolved question is whether endocrine dysfunction is driven primarily by target-tissue insulin resistance, intrinsic β-cell failure, immune/inflammatory stress, or combined multi-organ failure that differs by disease stage.
