In Vitro
Cobolimab (0.0001-10 nM; 3 d) promotes TIM-3 internalization in a dose dependent manner in pre-activated T cells with an IC50 value of 0.4464 nM[3].
Cobolimab (20 µg/mL; 24 h) significantly increases CD8+ T cell content by inhibiting TIM-3[4].

Flow cytometric analysis of 1.5X106 MCF-7 cells with Cobolimab (HY-P99827, red). Cells were fixed with 4% paraformaldehyde. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. AF488-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 IgG1 kappa (HY-P99001, blue) was used as the isotype control. -
Loaded Cobolimab on AHC2 biosensor, can bind IL-1 beta Protein, Human (C-His, HY-P78459A) with an affinity constant of 7.523E-10 M as determined in BLI assay.
