Function

Involved in the maintenance and repair of the intestinal mucosa. Promotes the mobility of epithelial cells in healing processes (motogen).

Biological Context

Subcellular Location: Secreted, extracellular space, extracellular matrix; Cytoplasm
Tissue Specificity: Expressed in goblet cells of the intestines and colon (at protein level). Expressed by goblet cells of small and large intestinal epithelia and also by the uterus. Also expressed in the hypothalamus where it is detected in paraventricular, periventricular and supraoptic nuclei (at protein level)

Product Specifications

Recombinant Human Trefoil factor 3 protein (TFF3) is a recombinant protein from Homo sapiens (Human), expressed in E.Coli, covering amino acids 22-80aa, with Tag-Free tag, molecular weight 6.6 kDa, purity >97% as determined by SDS-PAGE.. Suitable for ELISA and Western Blot applications.

SDS-PAGE: Single band at expected molecular weight confirming purity.
