生物活性

Pabinafusp alfa (JR-141) is a transferrin receptor-targeting antibody consisting of Iduronate 2-sulfatase (HY-P76399) and an anti-human transferrin receptor antibody. Pabinafusp alfa is blood-brain permeable and prevents heparan sulfate (HS) deposition in the central nervous system of mucopolysaccharidosis II (MPS II) mice. Pabinafusp alfa improves learning and prevents central nervous system neuronal damage in mice[1].

IC50 & Target

Transferrin receptor[1]

体内研究
(In Vivo)

Pabinafusp alfa (0.1-2 mg/kg;静脉注射;每周一次,持续 36 周) 剂量依赖性地预防 MPS II 小鼠模型的神经组织病理学变化并改善神经缺陷[1]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Mouse model of MPS II[1]
Dosage: 0.1 mg/kg, 0.5 mg/kg, and 2 mg/kg
Administration: Intravenous injection; once weekly for 36 weeks
Result: Dose-dependently decreases the level of heparan sulfate (HS) in the brain and cerebrospinal fluid (CSF), as well as decreasing the substrate concentrations.
Recovered spontaneous alterations in a dose-dependent manner, indicating an impaired working memory prevented.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
