Description: Stability and Storage:The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 10% prior to the expiration date under appropriate storage condition. Detection method:Colorimetric Sample type:Plasma, Serum Assay type:Quantitative Sensitivity:0.156 μg/ml Range:0.31-5 μg/mL Recovery:80-120% Background:Toripalimab is an anti-PD-1 monoclonal antibody developed for its ability to block PD-1 interactions with its ligands, PD-L1 and PD-L2, and for enhanced receptor endocytosis function. PD-L1 and PD-L2 are tumor checkpoint proteins which recognize the PD-1 receptor on T cells and exhaust their anti-tumor activity. Blocking PD-1 interactions with PD-L1 and PD-L2 is thought to recharge the immune system’s ability to attack and kill tumor cells. Shipping:2-8 ℃ Specifications:Toripalimab Note:For Research Use Only.
