Purification	Protein A/G purified from cell culture supernatant.
Biological activity	AO-176 shows EC 50 values of 130 ng/mL (OV90), 390 ng/mL (HCC827), 649 ng/mL (SNU-1), 250 ng/mL (OV10-315), 2700 ng/mL (MDA-MB-231), 390 ng/mL (Jurkat) and 1910 ng/mL (Raji) [1]. AO-176 (10 ug/mL, 24 h) induces death of Jurkat and OV90 cells [1]. AO-176 (0.017-1000 ug/mL) binds negligibly to RBCs and does not cause agglutination of washed human RBCs [1][3]. AO-176 (10-30 ug/mL, 24 h) has no killing effect on normal cell and the activated T cells [1]. AO-176 (0.001-100 ug/mL, 90 min) directly inhibits the binding of SIRPα to CD47 on Jurkat cells with an IC 50 of 0.78 to 0.87 ug/mL [1]. AO-176 (0.01-10 ug/mL, 2 h) promotes the phagocytosis of both Jurkat, Raji, OV90, Detroit 562, and FaDu cells in a concentration-dependent manner [1][2][4]. AO-176 (1-25 mg/kg, i.v., weekly for 4 weeks) significantly suppresses the tumor growth in Raji lymphoma xenograft mice models [1]. AO-176 (10-25 mg/kg, i.p., weekly or 5 times/weeks for 5-6 weeks) significantly suppresses the tumor growth in MDA-MB-23, SNU-1 and OV90 xenograft mice models [1]. AO-176 (3-25 mg/kg) exerts anti-tumor activity in RPMI-8226 and NCI-H929 xenografted mice models [3][4]. .
