Anti-TFF1 Antibody

The TFF1 target (Trefoil Factor 1, also called pS2) is a small secreted peptide best known for protecting and repairing gastrointestinal mucosa. This unconjugated rabbit polyclonal reagent from Antibodies.com was raised against TFF1 and recognizes the human, mouse, and rat proteins in western blot workflows. The antibody is supplied at 1 mg/ml in phosphate buffered saline (PBS) containing 0.05% sodium azide, at approximately pH 7.3, and ships as a 100 µl aliquot. Researchers studying gastric biology, mucosal defense, or estrogen-responsive breast tissue use this reagent to detect endogenous TFF1 expression by immunoblotting. The polyclonal format works well for probing the mature trefoil domain in lysates prepared from stomach, intestinal, and breast carcinoma cell lines. Store refrigerated and protect from light to preserve activity; the sodium azide in the buffer prevents microbial contamination during routine bench use.
