>95% as determined by SDS-PAGE
Form/Format
Lyophilized Powder
Sequence Length
189
Bioactivity
The ED(50) was determined by the dose-dependent proliferation of KMS15 cells and was found to be <0.05ng/mL.

<1.0 EU/ug of recombinant protein as determined by the LAL method
Preparation and Storage
The lyophilized protein is stable for at least one year from date of receipt at-70 degree C. Upon reconstitution, this cytokine can be stored in working aliquots at 2-8 degree C for one month, or at-20 degree C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

Related Product Information for IFNA4 active protein
All known subtypes of IFN-alpha show the same antiviral antiparasitic, antiproliferative activities. IFN-alpha forms are produced by monocytes/macrophages, lymphoblastoid cells, fibroblasts, and a number of different cell types following induction by viruses, nucleic acids, glucocorticoid hormones, and low-molecular weight substances. All IFN-alpha subtypes possess a common conserved sequence region between amino acid positions 115-151 while the amino-terminal ends are variable. Many IFN-alpha subtypes differ in their sequences at only one or two positions. IFN-alpha and IFN-beta are thought to bind to the same receptor. Signal transduction mechanisms elicited after binding of IFN-alpha to its receptors involves tyrosine phosphorylation (see also: PTK; protein tyrosine kinase) of various non-receptor tyrosine kinases belonging to the Janus kinases.

Product Notes
The IFNA4 ifna4 (Catalog #AAA4159850) is an Active Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "IFNA4, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
