The TFF1 Antibody (CAB1789) is a high-quality antibody developed for reliable detection and analysis of target proteins. Members of the trefoil family are characterized by having at least one copy of the trefoil motif, a 40-amino acid domain that contains three conserved disulfides. They are stable secretory proteins expressed in gastrointestinal mucosa. Their functions are not defined, but they may protect the mucosa from insults, stabilize the mucus layer, and affect healing of the epithelium. This gene, which is expressed in the gastric mucosa, has also been studied because of its expression in human tumors. This gene and two other related trefoil family member genes are found in a cluster on chromosome 21.
This antibody is validated for use in WB, IHC-P, ELISA applications and has demonstrated reactivity against Human, Mouse, Rat samples.
