General Description of Recombinant Human IFN a 2b.
Human IFN-a 2b produced in HEK cells is a glycosylated monomer, having a total molecular weight of 16kDa. The IFN-a 2b is purified by using an optimized multi-step FPLC method for maximum separation from contaminants.

Human IFN a 2b Bioactive Protein Product Attributes

Product Type: Bioactive Protein
Recombinant IFN a 2b based upon sequence from Human
Host: QP10674 protein expressed in HEK 293, E. Coli, S. cerevisiae.
Available Tags: Untagged, 20kD PEG
Protein Construction: A cDNA sequence encoding the sequence of IFN a 2b was constructred and used to recombinantly synthesize the protein.
Recommended Applications: Bioactive
Application Notes
Recommended Reconstitution Instructions: It is recommended to reconstitute the lyophilized IFN-a 2b in sterile water not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Bioactivity Data: The specific activity was determined by the dose-dependent cytotoxicity of the human TF-1 cell line (human erythroleukemic indicator cell line) and is typically 0.02-0.08ng/ml.
Purity: Greater than 95% as obsereved by SDS-PAGE.
Endotoxin Levels: < 1.0 EU per ug protein as determined by the LAL method.
Buffer: The IFN-a 2b was lyophilized from 1 mg/ml in 1xPBS.
Storage Conditions: Lyophilized IFN-a 2b although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IFN-a 2b should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
