Rolinsatamab is a IgG1κ type chimeric antibody targeting to PRLR (prolactin receptor). Rolinsatamab can be conjugated with pyrrolobenzodiazepine (PDB) dimer SGD-1882 (HY-101127) via a cleavable maleimidocaproyl type linker, to form an antibody-drug conjugate, Rolinsatamab talirine. One Rolinsatamab talirine has an average of 2 site-specific drug attachment engineered cysteines (C242, C242'). The linker equips the valine-alanine dipeptide, as cathepsine B cleavage site. on an average of 2 site-specific drug attachment engineered cysteines (C242, C242').

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
