CM-24
Based on 1 Customer Validation
CM-24 (MK-6018) is a highly selective humanized monoclonal antibody targeting CEACAM1/CD66a. CM-24 binds to the N-terminal domain of CEACAM1, blocks the CEACAM1-CEACAM1 interaction, relieves the co-inhibitory effect on CEACAM1-positive lymphocytes, and enhances the cytotoxic activity of TIL, LAK and NK cells against CEACAM1-positive tumor cells. CM-24 can be used in studies related to tumor immunology, tumor metastasis and thrombosis. For the isotype control of CM-24, refer to Human IgG1 kappa, Isotype Control (HY-P99001).

CM-24 (MK-6018) (0.1-10 μg/mL; pre-treated for 30 min followed by 24 h co-culture) dose-dependently enhances the cytotoxic activity of human LAK cells against SK-MEL-28 melanoma cells[2].
CM-24 (0.1-10 μg/mL; 30 min pre-treatment followed by 24 h co-culture) enhances the cytotoxic activity of LAK cells against T3M4, SU8686 and PANC2 pancreatic cancer cells as well as H358 and H460 lung cancer cells, and increases the secretion of Granzyme B and IFNγ[2].
CM-24 (20 μg/mL; 1 h) specifically binds to NET structures formed by PMA (HY-18739)-stimulated primary human neutrophils, while no detectable staining is observed with the human IgG4 isotype control[3].
CM-24 (500 μg/mL; 24-48 h) inhibits NETs (20 ng/μL)-induced migration of SK-MEL-28, A549 and AsPC-1 cells by 69.5%, 82.7% and 49.1%, respectively[3].
CM-24 (500 μg/mL; pre-treated for 30 min followed by 2 h of incubation) significantly reduces the adhesion of CEACAM1-positive SK-MEL-28 cells to 4 ng/μL NETs[3].
CM-24 (500 μg/mL; 30 min pre-treatment) reduces platelet aggregation induced by 5 and 10 ng/μL fresh NETs by 70% and 53%, respectively, compared with IgG4 isotype control[3].

Combination of CM-24 (1-10 mg/kg; i.v.; twice weekly) with melanoma-reactive TIL reduces the median number of lung lesions to 5, 6, 3, and 2, respectively, compared with 45 in the TIL plus control IgG group[2].
CM-24 (25-100 mg/kg; intravenous infusion; once every 2 weeks; 4 doses administered over 6 weeks) causes no treatment-related toxicity, mortality or pathological changes in rhesus monkeys[2].

Immobilized CEACAM1 Protein, Human can bind CM-24. The EC50 for this effect is 3.38 ng/mL. -
Flow cytometric analysis of 1.5X106 HT-29 cells with CM-24 (HY-P990569, red). Cells were fixed with 4% paraformaldehyde. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. 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 (HY-P99001, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
