Recombinant Human IL37 Protein

• Cat.No.: IL37-108H
• Product Overview: Recombinant Human Interleukin-37 is produced by our E.coli expression system and the target gene encoding Lys53-Asp218 is expressed.

Specification

• Species: Human
• Source: E.coli
• Protein Length: 53-218 a.a.
• Description: Human Interleukin family 1 Member 7 (IL1F7) is a member of the Interleukin 1 cytokine family. Five alternatively spliced transcript variants encoding distinct isoforms have been reported with distinct expression profiles. The longest IL1F7 transcript, referred to as IL1F7b or IL1F7 isoform 1, encodes a 218 amino acid residues proprotein containing a 45 amino acid propeptide, which is cleaved to generate mature protein. IL1F7b binds to IL18 Rα with low affinity but does not exert any IL18 agonistic or antagonistic effects. IL1F7b also binds interleukin 18 binding protein (IL-18BP), an inhibitory binding protein of interleukin 18 (IL-18), and subsequently forms a complex with IL18 receptor beta subunit, and through which it inhibits the activity of IL-18.
• Form: Lyophilized from a 0.2 um filtered solution of 20mM PB, 150mM NaCl, 2mM DTT, pH 7.4
• Molecular Mass: Predicted Molecular Weight: 18.7kDa
  Apparent Molecular Weight: 18kDa, reducing conditions.
• AA Sequence: Lys53-Asp218
• Endotoxin: Less than 0.1 ng/ug (1 EU/ug).
• Purity: >95%
• 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.
• Quality Statement: Purity Greater than 95% as determined by reducing SDS-PAGE.
• Shipping: The product is shipped at ambient temperature.
  Upon receipt, store it immediately at the temperature listed below.
