Human IL 28B Bioactive Protein Product Attributes
Product Type: Bioactive Protein
Recombinant IL 28B based upon sequence from Human
Host: QP10709 protein expressed in HEK 293.
Available Tags: Untagged
Protein Construction: A cDNA sequence encoding the sequence of IL 28B was constructred and used to recombinantly synthesize the protein.
Recommended Applications: Bioactive
Recommended Reconstitution Instructions: It is recommended to reconstitute the lyophilized IL-28B 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 protection of the cytopathic effect on A549 cells (human lung adenocarcinoma epithelial cell line) that were challenged with encephalomyocarditis (EMC) virus and is typically 0.1-1ng/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 IL28B was lyophilized from 1 mg/ml in 1xPBS.
Storage Conditions: Lyophilized IL-28B although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL28B 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.
