TFF1 Protein, Human

Customer Review

Based on 1 Customer Validation

TFF1 protein functions as a mucous gel stabilizer, vital for fortifying the gastrointestinal mucosa against noxious agents. It contributes to the mucous layer's integrity, providing a crucial physical barrier for the gastrointestinal tract, safeguarding it from potential harm. TFF1's stabilizing role emphasizes its significance in preserving the mucosal barrier, essential for overall gastrointestinal health and protection. TFF1 Protein, Human is the recombinant human-derived TFF1 protein, expressed by E. coli , with tag free.

Description

TFF1 protein functions as a mucous gel stabilizer, vital for fortifying the gastrointestinal mucosa against noxious agents. It contributes to the mucous layer's integrity, providing a crucial physical barrier for the gastrointestinal tract, safeguarding it from potential harm. TFF1's stabilizing role emphasizes its significance in preserving the mucosal barrier, essential for overall gastrointestinal health and protection. TFF1 Protein, Human is the recombinant human-derived TFF1 protein, expressed by E. coli , with tag free.

Background

Trefoil Factor 1 (TFF1) protein acts as a stabilizer for the mucous gel that overlays the gastrointestinal mucosa, playing a crucial role in providing a robust physical barrier against a variety of noxious agents. By contributing to the integrity of the mucous layer, TFF1 aids in the protection and defense of the gastrointestinal tract from potential harmful substances. Its stabilizing function underscores its importance in maintaining the mucosal barrier, which is essential for the overall health and protection of the gastrointestinal mucosa.

Verified Bioactivity

Measured by its ability to induce ERK1/ERK2 phosphorylation in Jurkat human acute T cell leukemia cells. 10μg/mL of Recombinant Human TFF1 can effectively induce ERK1/2 phosphorylation.
