Glycoprotein 130 (gp130) is a trans-membrane protein, is the common signal-transducing receptor subunit of the interleukin-6 (IL-6) family[1]. gp130 inhibits the cell growth and migration[3], decreases the STAT3 phosphorylation induced by IL-6, and decreases IL-6-induced increase of Ki67. gp130 shows anti-tumor, anti-inflammation and anti-nociceptive activity[4][5]. gp130/IL6ST Protein, Human (HEK293) is a recombinant protein consisting of 596 amino acids (M23-I618) and is produced by HEK293 cells.
