The FDA has granted an orphan drug designation to sotigalimab (APX005M) as a potential therapeutic option for patients with soft tissue sarcoma, according to an announcement from Apexigen Inc., the drug developer.A novel, humanized monoclonal antibody, sotigalimab was designed to stimulate an antitumor immune response and to target CD40, which is a key co-stimulatory receptor that serves to activate innate and adaptive immune systems. When sotigalimab binds to CD40 on antigen-presenting cells, it induces a multifaceted immune response that brings several components of the immune system together to attack the cancer.

SEC-HPLC	SEC-HPLC detection for Research Grade Sotigalimab.
Bioactivity	Detects CD40/TNFRSF5 in indirect ELISAs.
Flow CytoMetry	Flow-cytometry using APC anti-human CD40 antibody. U2OS cells were stained with an irrelevant antibody (Blue Histogram) or an APC anti-human CD40 monoclonal antibody (Catalog: HB782116, Yellow Histogram) at a concentration of 5 µg/ml for 30 mins at RT. After washing, and cells analysed on a NovoCyte Flow Cytometer.
Flow CytoMetry	Flow-cytometry using FITC anti-human CD40 antibody.
