제품 설명

TGF α/TGFA is a mitogenic peptide that binds to the EGF receptor (EGFR) and acts synergistically with TGF β to achieve anchorage-independent cell proliferation in soft agar.It interacts with SDCBP and the SNTA1 PDZ domain, which is critical for cell surface localization.TGF alpha/TGFA Protein, Mouse (HEK293, Fc) is the recombinant mouse-derived TGF alpha/TGFA protein, expressed by HEK293 , with N-hFc labeled tag.

Background

TGF alpha, a mitogenic polypeptide, exhibits the ability to bind to the EGF receptor (EGFR) and synergistically collaborate with TGF beta to facilitate anchorage-independent cell proliferation in soft agar. It interacts with the PDZ domains of SDCBP and SNTA1, with the former being crucial for its localization to the cell surface. In its immature form, present in the endoplasmic reticulum and characterized by a prosegment and partial N-glycosylation, TGF alpha interacts with CNIH. Within the Golgi apparatus, it may form a complex with CNIH and GORASP2. Additionally, TGF alpha interacts with NKD2 through its cytoplasmic C-terminal domain and with MAGI3.

Biological Activity

Measured in a cell proliferation assay using Balb/3T3 mouse embryonic fibroblast cells. The ED50 for this effect is <0.4 ng/mL.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O.

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×
C1   V1   C2   V2

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
