• Source: E. coli
• Protein/Peptide Type: Recombinant Protein
• Gene: IFNW1
• Purity: > 97 % pure by SDS-PAGE and HPLC
• Endotoxin Note: Less than 1 EU/ug of IFN-omega/IFNW1 as determined by LAL method.

Applications/Dilutions

• Dilutions:
  • Bioactivity
  • SDS-Page
• Theoretical MW: 20.0 kDa.
  Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Packaging, Storage & Formulations

• Storage: Store at -20 to -70C as supplied. After reconstitution, store at 2 to 8C for 1 month and at -20 to -70C for long term storage. Avoid repeated freeze-thaw cycles.
• Buffer: Lyophilized from a 0.2 um filtered concentrated solution in PBS, pH 7.4.
• Preservative: No Preservative
• Concentration: LYOPH
• Purity: > 97 % pure by SDS-PAGE and HPLC
• Reconstitution Instructions: Recommended to centrifuge prior to opening. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0mg/mL. Apportion stock solutions into working aliquots and store at <-20C.

Notes

This lyophilized preparation is stable at 2-8 degrees C, but should be kept at -20 degrees C for long term storage, preferably desiccated. Upon reconstitution, the preparation is most stable at -20 to -80 degrees C, and can be stored for one week at 2-8 degrees C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 degrees C to -80 degrees C. Avoid repeated freeze/thaw cycles.

Background

Interferon-Omega (IFN-omega) coded by IFNW1 gene in human, is a number of the type I interferon family, which includes IFN-alpha, IFN-beta, and IFN-omega. The IFNAR-1/IFNAR-2 receptor complex can help with the signal transduction, followed the antiviral or the antiproliferative actions. IFN-omega is derived from IFN-alpha/beta and shares 75 % sequence homology with IFN-alpha. It has two intramolecular disulfide bonds which are crucial for activities. Mire-Sluis et al have described bioassays for IFN-alpha, IFN-beta, and IFN-omega that exploit the ability of these factors to inhibit proliferation of TF-1 cells induced by GM-CSF. The bioassays can be used also with Epo and TF-1 cells, or Epo and Epo-transfected UT-7 cells.
