Human Trefoil Factor-2 protein

• Catalog Number: orb80105
• Category: Proteins
• Description: TFF-2 Human Recombinant produced in E.coli is a single, non-glycosylated, polypeptide chain containing 106 amino acids (24-129) and having total molecular mass of 12 kDa. TFF2 Human Recombinant includes 40-amino acid trefoil motif containing three conserved intramolecular disulfide bonds and was purified by proprietary chromatographic techniques.
• Tested applications: FA, HPLC, SDS-PAGE
• Purity: > 97.0% as determined by RP-HPLC and analysis by SDS-PAGE
• Conjugation: Unconjugated
• Target: TFF2
• Solubility (25°C): It is recommended to reconstitute the lyophilized TFF2 in sterile H₂O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
• Protein Sequence: EKPSPCQCSR LSPHNRTNCG FPGITSDQCF DNGCCFDSSV TGVPWCFHPL PKQESDQCVM EVSDRRNCGY PGISPEECAS RKCCFSNFIF EVPWCFFPKSVEDCHY.
• Biological Origin: E.coli
• Biological Activity: Determined by its ability to chemoattract human MCF-7 cells using concentration 1.0-10.0 ng/ml.
• Storage: Store at 4°C for up to two weeks. For long term storage, aliquot and store at -20°C, avoid freeze/thaw cycles.
• Buffer/Preservatives: The TFF2 protein was lyophilized from 0.4 um filtered solution at concentration of 1mg/mL containing 1x PBS pH-7.4.
• Alternative names: TFF-2 protein, Spasmolytic polypeptide protein, Sp
