Cystatin S
Cystatin S, the product of CST4, is a type 2 cystatin concentrated in saliva, tears, and nasal secretions, where it contributes to the first line of mucosal defense by inhibiting cathepsins B, L, S, and H released during inflammation or tissue turnover. Its secretion is regulated in response to dietary and inflammatory stimuli, and salivary cystatin S levels change in periodontal disease. Elevated expression has also been reported in certain tumors, making it a candidate diagnostic marker. Recombinant cystatin S is used for oral-biology research, cysteine-protease inhibition assays, and biomarker studies.

The EpCAM/TROP1 protein serves as an important homogeneous interacting molecule that promotes direct contact between intestinal epithelial cells (IEC) and intraepithelial lymphocytes (IEL) in the mucosal epithelium. This feature helps establish an immune barrier against mucosal infections. EpCAM/TROP1 Protein, Human (His-SUMO) is the recombinant human-derived EpCAM/TROP1 protein, expressed by E. coli , with N-6*His, N-SUMO labeled tag.
