Recombinant Human IL6ST

Specification :
| Cat. No. : IL6ST-1682H | Description : Glycoprotein 130 (also known as gp130, IL6ST, IL6-beta or CD130) is a transmembrane protein which is the founding member of the class of tall cytokine receptors. It forms one subunit of type I cytokine receptors within the IL-6 receptor family. It is often referred to as the common gp130 subunit, and is important for signal transduction following cytokine engagement. Gp130 signals are mediated by tyrosine kinases of the JAK family and by their binding partners, transcription factors of the STAT family. Gp130 signaling is very important for osteoblast function and calcium homeostasis. | Molecular Weight : The predicted molecular weight of Recombinant Human soluble gp130 is Mr 68 kDa. | Source : Sf 21 Insect Cells. | State Of Matter : Lyophilized. | Purity : >95% by SDS Page and analyzed by silver stain. | Endotoxin : | Biological Activity : The biological activity of Human soluble gp130 was determined by its ability to inhibit the IL-6 sR enhancement of IL-6 activity on a mouse myeloid leukemia cell line, M1 (Saito, T. et al., 1991, J. Immunol. 147:168). The expected ED50 for this effect is typically 0.5-2 μg/mL in the presence of 10 ng/mL rhIL-6 sR and 20 ng/mL rhIL-6. | Storage And Stability : This lyophilized protein is stable for six to twelve months when stored desiccated at -20℃ to -70℃. After aseptic reconstitution, this protein may be stored at 2℃ to 8℃ for one month or at -20℃ to -70℃ in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions.
