Trefoil Factor 1, Recombinant, Human, aa25-84, His-tag (Tff1, Bcei, Ps2, Protein pS2)

TFF1 (Trefoil factor 1) is member of trefoil family, characterized by having at least one copy of the trefoil motif, a 40-amino acid domain that contains three conserved disulfides. Trefoil peptides are protease resistant molecules secreted throughout the gut that play a role in mucosal healing. TFF1 has also been detected in a number of carcinomas including cancers of the breast, pancreas and stomach. Purified by using conventional chromatography techniques.\n\nSource:\nRecombinant corresponding to aa25-84 of human TFF1, fused to His-tag at N-terminal, expressed in E.coli.\n\nAA Sequence:\nMGSSHHHHHH SSGLVPRGSH MEAQTETCTV APRERQNCGF PGVTPSQCAN KGCCFDDTVR GVPWCFYPNT IDVPPEEECE F\n\nMolecular Weight: \n~9kD (81aa), confirmed by MALDI-TOF\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only.
