| Biochem/physiol Actions【生化/生理作用】 | Interleukin-4, a lymphokine with profound effects on the growth and differentiation of immunologically competent cells, inhibits VEGF-induced and bFGF-induced angiogenesis. Human and mouse IL-4 share 50% amino acid sequence identity, but their biological actions are species-specific. Interleukin-4 is a lymphokine with profound effects on the growth and differentiation of immunologically competent cells. IL-4 is also known as B cell stimulatory factor-1 (BSF-1), T cell growth factor-2 (TCGF-2) and mast-cell growth factor-2 (MCGF-2). Inhibits VEGF-induced and bFGF-induced angiogenesis. IL-4 is a complex glycoprotein released by a subset of activated T cells. Human and mouse IL-4 share 50% amino acid sequence homology, but their biological actions are species-specific. |
| Physical form【外形】 | Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline containing 0.25 mg bovine serum albumin. |
| Analysis Note【分析说明】 | The biological activity of recombinant rat IL-4 was measured by its ability to stimulate proliferation of rat splenocytes. |
