Demoxytocin
Based on 1 Customer Validation
Demoxytocin is a heterologous cyclic peptide and an analog of Oxytocin (HY-17571). Demoxytocin affects the permeability of cell membranes and increases calcium ion levels in smooth muscle cells, thereby enhancing the contraction of smooth muscle cells. Demoxytocin also stimulates the contraction of uterine smooth muscle. Demoxytocin possesses the functions of oxytocin. Demoxytocin can be used to study labor stimulation in preterm premature rupture of membranes.

In Vitro
Demoxytocin is absorbable via mucous membranes and can be administered buccally: placed between the cheek and gum, it is directly absorbed through the oral mucosa, which avoids the hepatic first-pass effect of oral administration and the inconvenience of intravenous injection[1][2].

Transepithelial/transendothelial electrical resistance assay
TEER measures electrical resistance across epithelial or endothelial monolayers cultured on permeable supports, and the readout reflects ionic conductance through the cell barrier, especially the paracellular pathway regulated by junctional integrity. TEER can be measured without destroying the monolayer and is commonly used before or during transport, permeability, barrier-disruption, and barrier-maturation experiments. TEER values are influenced by biological maturation and technical conditions; reported factors include temperature, medium formulation, passage number, electrode geometry, membrane properties, and junctional length during early monolayer maturation. Therefore, TEER should be interpreted with blank-insert subtraction, area normalization, repeated readings, and, when possible, orthogonal barrier readouts such as FITC-dextran flux or tight-junction staining.
