Tofacitinib-¹³C₃ (Tasocitinib-¹³C₃; CP-690550-¹³C₃) is the ¹³C-labeled Tofacitinib (HY-40354). Tofacitinib (Tasocitinib) is an orally active, blood-brain barrier permeable selective inhibitor of JAK1/JAK3. Tofacitinib blocks the JAK-STAT/NF-κB signaling pathway, inhibits cytokine signal transduction, phosphorylation of STAT1/STAT5, and suppresses innate and adaptive immune responses. Tofacitinib can be used in research related to major depressive disorder, rheumatoid arthritis, pulmonary diseases, systemic lupus erythematosus, and immune-mediated liver injury.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
