Cat#:RP-6058H;Product Name:Recombinant Human TFF3 Protein;Synonym:TFF-3, ITF, TFI, HITF, hP1.B, TFF3, Trefoil factor 3, Intestinal trefoil factor.;Description:TFF-3 Protein produced in E.coli is a homodimeric, non-glycosylated, polypeptide chain containing 2 x 59 amino acid chains which includes a 40 amino acid trefoil motif containing 3 conserved interamolecular disulfide bonds and having a total molecular mass of 13.2kDa. TFF-3 Protein is purified by proprietary chromatographic techniques.;Source:E.coli;AA Sequence:EEYVGLSANQ CAVPAKDRVD CGYPHVTPKE CNNRGCCFDS RIPGVPWCFK PLQEAECTF.;Purity:Greater than 97.0% as determined by RP-HPLC and SDS-PAGE analysis.;Bioactivity:The ED50 as determined by a chemotaxis bioassay using human MCF-7 cells is less than 10µg/ml, corresponding to a specific activity of > 100IU/mg.;Formulation:Lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized TFF3 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized TFF3 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TFF3 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.;

TFF-3 Protein is purified by proprietary chromatographic techniques.
Greater than 97.0% as determined by RP-HPLC and SDS-PAGE analysis.
Bioactivity:
The ED50 as determined by a chemotaxis bioassay using human MCF-7 cells is less than 10µg/ml, corresponding to a specific activity of > 100IU/mg.
Formulation:
Lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4.
Stability:
Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃
Reconstitution:
It is recommended to reconstitute the lyophilized TFF3 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Storage:
Lyophilized TFF3 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TFF3 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
