Active Recombinant Human IL6 Protein

• Cat.No.: IL6-196H
• Product Overview: Recombinant Human Interleukin-6 is produced by our E. coli expression system and the target gene encoding Val30-Met212 is expressed.

Specification

• Description: Cytokines of the IL6/GCSF/MGF family are glycoproteins of about 170 to 180 amino acid residues that contain four conserved cysteine residues involved in two disulfide bonds. They have a compact, globular fold (similar to other interleukins), stabilized by the 2 disulfide bonds. One half of the structure is dominated by a 4 alpha-helix bundle with a left-handed twist; the helices are anti-parallel, with 2 overhand connections, which fall into a 2-stranded anti-parallel beta-sheet. The fourth alpha helix is important to the biological activity of the molecule. Interleukin-6 (IL-6) is an important proinflammatory and immunoregulatory cytokine expressed by various cells. Interleukin-6 has been shown to inhibit the growth of early stage and to promote the proliferation of advanced stage melanoma cells in vitro.

• Storage: Lyophilized protein should be stored at < -20 centigrade, though stable at room temperature for 3 weeks.
  Reconstituted protein solution can be stored at 4-7 centigrade for 2-7 days.
  Aliquots of reconstituted samples are stable at < -20 centigrade for 3 months.
• Reconstitution: Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
  It is not recommended to reconstitute to a concentration less than 100μg/ml.
  Dissolve the lyophilized protein in distilled water.
  Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
