生物活性

Larazotideis a peptide which is an orally active zonulin antagonist. Larazotide shows antiviral activity to varicella-zoster virus (VZV) with EC50s of 44.14 and 59.06 μM for strain OKA and 07-1, respectively. Larazotide can be used for the research of celiac disease and infection[1][2].

体外研究
(In Vitro)

Larazotide (1-100 μM; 5 d) affects Vero cell growth[1].
Larazotide (1-100 μM; 3 d) shows antiviral activity to varicella-zoster virus (VZV) with EC50s of 44.14 and 59.06 μM for strain OKA and 07-1, respectively[1].
Larazotide (1 and 3 mM; 72 h) inhibits cytokine-induced tight junction permeability in Caco-2 cells[2].
Larazotide (100 μM; 3 h) inhibits gliadin translocation across Caco-2 monolayers[2].
Larazotide (12.5 mM; 1 h) inhibits PTG-induced ZO-1 redistribution and actin cytoskeletal rearrangement in IEC6 cells[2].

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

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.
