IL-32 Protein, Human, Recombinant (isoform alpha, His Tag) Product Information
> 95 % as determined by SDS-PAGE
< 1.0 EU per μg of the protein as determined by the LAL method
Testing in progress
A DNA sequence encoding the human IL32 isoform alpha (IL32A) (NP_001012651.1) precursor (Met 1-Lys 131) was expressed with a polyhistidine tag at the C-terminus.
Predicted N Terminal
The recombinant human IL32A comprises 137 amino acids with a predicted molecular mass of 15.7 kDa. As a result of glycosylation, it migrates as an approximately 20 kDa band in SDS-PAGE under reducing conditions.
Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us
for any concerns or special requirements.Please refer to the specific buffer information in the hard copy of CoA.
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Stability & Storage
Samples are stable for up to twelve months from date of receipt at -70℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

IL-32 Background Information
IL-32 is a recently discovered cytokine that induces various proinflammatory cytokines (TNF-alpha, IL-1beta, IL-6) and chemokines in both human and mouse cells through the NF-kappaB and p38 MAPK inflammatory signal pathways. It is regulated robustly by other major proinflammatory cytokines, and is crucial to inflammation and immune responses. Four of the IL-32 isoforms (alpha, beta, gamma and delta) are the most representative IL-32 transcripts, and gamma isoform of IL-32 is the most active, although all isoforms are biologically active. IL-32, a cytokine produced mainly by T, natural killer, and epithelial cells induces significant amounts of TNFalpha and MIP-2 and increases the production of both cytokines in a dose-dependent manner. IL-32 has been implicated in inflammatory disorders, mycobacterium tuberculosis infections, inflammatory bowel disease, and influenza A virus infection, as well as in some autoimmune diseases, such as rheumatoid arthritis, ulcerative colitis and in human stomach cancer, human lung cancer and breast cancer tissues. Thus, IL-32 expression might be valuable as a biomarker for cancer.
