In Vitro

Most native cells express a variety of different calcium channels and as a result, Ziconotide only partially reduces high-voltage-activated calcium currents in differentiated human neuroblastoma IMR32 cells, rat superior cervical ganglion neurons, and rat hippocampal neurons. Ziconotide also reduces calcium currents that result from expression of the α1B subunit in HEK cells, tsa-201 cells, and Xenopus laevis oocytes[1].
Ziconotide delivers its antinociceptive efficacy by reducing the release of pronociceptive neurotransmitters in the dorsal horn of the spinal cord, thereby inhibiting pain signal transmission[1].

In Vivo

Ziconotide (i.t.; 25-100 pmol/site; 5 μL; on the 4 th, 10 th, 15 th, 20 th, and 24 th days) reduces the levels of IL-1β and IL-23 in the CNS, as well as IL-17 production in the spleen, 25 days after MOG35-55-elicited EAE, in the mouse model of experimental autoimmune encephalomyelitis (EAE)[2].

Animal Model: Female C57BL/6mice (18-22 g, 6-8 weeks old) injected with myelin oligodendrocytes glycoprotein[2]
Dosage: 25 pmol/site, 50 pmol/site, 100 pmol/site
Administration: Intrathecal injection; on the 4 th, 10 th, 15 th, 20 th, and 24 th days
Result: Significantly reduced the mechanical hypersensitivity in animals with EAE.

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.
