  • Synonym
    Transforming growth factor-alpha
  • Source
    Human TGF-alpha Protein, premium grade(TGA-H5119) is expressed from E. coli cells. It contains AA Val 40 - Ala 89 (Accession # P01135-1).
    Predicted N-terminus: Met
    It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. We will work with you to customize and develop a GMP-grade product in accordance with your requests that also meets the requirements for raw and ancillary materials use in cell manufacturing of cell-based therapies.
  • Molecular Characterization
    TGF-alpha Structure

    This protein carries no "tag".

    The protein has a calculated MW of 5.7 kDa. The protein migrates as 8 kDa±3 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE).

  • Endotoxin
    Less than 0.01 EU per μg by the LAL method / rFC method.
  • Host Cell Protein
    <0.5 ng/µg of protein tested by ELISA.
  • Host Cell DNA
    <0.02 ng/μg of protein tested by qPCR.
  • Sterility
    Negative
  • Mycoplasma
    Negative
  • Purity

    >95% as determined by SDS-PAGE.

    >95% as determined by SEC-HPLC.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

    1. -20°C to -70°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
SDS-PAGE
TGF-alpha SDS-PAGE

Human TGF-alpha Protein, premium grade on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).

SEC-HPLC
TGF-alpha SEC-HPLC

The purity of Human TGF-alpha Protein, premium grade (Cat. No. TGA-H5119) was greater than 95% as determined by SEC-HPLC.

Bioactivity-CELL BASE
 TGF-alpha CELL

Human TGF-αlphα Protein, premium grade (Cat. No. TGA-H5119) induced Human EGF R (Luc) HEK293 Reporter Cell. The EC50 for this effect is 4.606 ng/mL (Routinely tested).

Bioactivity-ELISA
 TGF-alpha ELISA

Immobilized Human TGF-alpha Protein, premium grade (Cat. No. TGA-H5119) at 2 μg/mL (100 μL/well) can bind Biotinylated Human EGF R, Fc,Avitag (Cat. No. EGR-H82F8) with a linear range of 0.3-39 ng/mL (QC tested).

  • Background
    TGF-alpha is a normal physiological ligand for the EGF receptor. TGF-α and the EGF receptor are expressed in many developing and adult tissues, where TGF-α has been implicated in cell migration, growth, and differentiation.
