PY314
Based on 1 Customer Validation
PY314 is a humanized antibody targeting TREM2. PY314 binds TREM2 on tumor-associated macrophages, depletes TREM2-high tumor-associated macrophages, reduces pro-tumorigenic M2 macrophage infiltration, increases CD8+ T cell, NK cell, and M1 macrophage infiltration, creates a proinflammatory tumor microenvironment, and promotes antitumor immune responseS. PY314 can be used for the research of platinum-resistant ovarian cancer, advanced solid tumors, breast cancer, and advanced refractory solid tumors.

Flow cytometric analysis of 1.5×106 THP-1 cells with PY314 (HY-P990651, red). 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).
