描述

TGF-alpha Protein, Human (CHO) is a potent angiogenic mediator and mitogenic polypeptide.

研究背景

Transforming growth factors (TGF's) are polypeptides that can confer phenotypic transformation to several normal cells. TGF-α binds to the receptor for epidermal growth factor (EGF) and has been isolated from a variety of tumor cells. TGF-α is synthesized in embryos during early fetal development, in several virally transformed cells, and in a large variety of human tumors[1]. TGF-α is a member of the epidermal growth factor family of mitogens and associated with progression of transformed properties in human colon cancer cells[2].

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.

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

浓度 (start) × 体积 (start) = 浓度 (final) × 体积 (final)
× = ×
C1   V1   C2   V2

The specific active calculator equation

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

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