Biological Activity

Description

IL-6 Protein, Human (CHO) is a potent inducer of the synthesis of acute phase proteins in adult human hepatocytes.

Background

Interleukin-6 (IL-6) is a 26-kD protein released by fibroblasts, T lymphocytes, endothelial cells, monocytes, and keratinocytes during inflammatory responses. IL-6 has pluripotent activities, including the stimulation of the monocytic lineage, the induction of megakaryopoiesis and the hepatic acute phase response, as well as the modulation of T- and B-cell responses. IL-6 is also capable of mediating direct and indirect tumor cell destruction and that it is potentially important for the immunotherapy of cancer [1]. Recombinant human interleukin-6 (IL-6/BSF-2/HSF) regulates the synthesis of acute phase proteins in human hepatocytes[2].

Verified Bioactivity

The ED50 is <1 ng/mL as measured in a cell proliferation assay using TF-1 cells.

Product Properties

Appearance

Lyophilized powder

Formulation

Lyophilized after extensive dialysis against 10 mM acetic acid or PBS.

Endotoxin Level

<0.2 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping

Room temperature in continental US; may vary elsewhere.
