Obexelimab (XmAb5871) is a humanized, Fc-engineered anti-CD19 antibody with enhanced affinity for FcγRIIb, utilized in the study of autoimmune diseases .

SFNGGP-NH2 is a biological active peptide. (PAR-3 is a high-affinity thrombin receptor. PAR-3 mRNA is expressed in the cutaneous mast cells of humans. Protease-Activated Receptors (PARs) have been studied for their roles in itch and their itch-associated response through histamine-dependent/independent pathways have been reported. PAR-3 has been shown not to induce itching alone but possibly in conjunction with PAR-4. Co-expression of PAR-3 and PAR-4 enhances thrombin action suggesting that PAR-3 alone does not mediate transmembrane signaling but instead functions as a cofactor to activate PAR-4.)

Azide-PEG12-alcohol is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs.
