Product Properties

Formulation Lyophilized from sterile 150mM NaCl 20mM Tris , pH 8.0.
Molecular weight 20.6 kDa
Usage notes Always centrifuge tubes before opening. It is recommended to reconstitute the lyophilized Human IL-6 protein in sterile ddH2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Storage instructions Lyophilized Human IL-6 protein should be stored desiccated below -20°C. Upon reconstitution, the protein should be stored at 4°C between 2-7 days and for future use below -20°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Shipping The product is shipped at ambient temperature.

Additional Information

Background Interleukin-6 (IL-6) is a multifunctional α-helical cytokine that regulates cell growth and differentiation of various tissues, which is known particularly for its role in the immune response and acute phase reactions. IL-6 protein is secreted by a variety of cell types including T cells and macrophages as phosphorylated and variably glycosylated molecule. It exerts actions through the its heterodimeric receptor composed of IL-6R that lacks the tyrosine/kinase domain and binds IL-6 with low affinity, and ubiquitously expressed glycoprotein 130 (gp130) that binds the IL-6. IL-6R complex with high affinity and thus transduces signals. IL-6 is also involved in hematopoiesis, bone metabolism, and cancer progression, and has been defined an essential role in directing transition from innate to acquired immunity.
