Larazotide acetate
Based on 4 publication(s) in Google Scholar
Larazotide acetate is a peptide which is an orally active zonulin antagonist. Larazotide acetate 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 acetate can be used for the research of celiac disease and infection.

Paracellular permeability[1]
Larazotide acetate (1-100 μM; 5 d) affects Vero cell growth[1]. Larazotide acetate (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 acetate (1 and 3 mM; 72 h) inhibits cytokine-induced tight junction permeability in Caco-2 cells[2]. Larazotide acetate (12.5 mM; 1 h) inhibits PTG-induced ZO-1 redistribution and actin cytoskeletal rearrangement in IEC6 cells[2].

Solvente y solubilidad
H2O : 50 mg/mL (63.62 mM; Need ultrasonic)
DMSO : 2 mg/mL (2.54 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year (sealed storage, away from moisture). When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
