The ED50 is <5 ng/mL as measured by HepG2 cells, corresponding to a specific activity of >2.0 × 105 units/mg. Appearance
Lyophilized powder. Formulation
Lyophilized after extensive dialysis against PBS, pH 7.4. Endotoxin Level
<1 EU/μg, determined by LAL method. Reconstitution
Reconstitute the lyophilized recombinant Human Interferon-lambda1/Interleukin-29 (rHuIFN-λ1/IL-29) to 0.1-1.0 mg/mL using sterile distilled water or aqueous buffer containing 0.1 % BSA. Storage & Stability
Lyophilized recombinant Human Interferon-lambda1/Interleukin-29 (rHuIFN-λ1/IL-29) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping
Room temperature in continental US; may vary elsewhere. Background
Human Interferon-lambda1/Interleukin-29 is produced by human peripheral blood mononuclear cells (PBMC) and dendritic cells, with antiviral, anti-proliferative and antitumor effects[1]. Human Interferon-lambda1/Interleukin-29 is a member of the interferon lambda family (also known as type III interferons), whose members are distantly related to both the type I interferons and members of the IL-10 family. IFN-λ1 also has important immunoregulatory property, especially with regard to the T helper type 2 (Th2) response[2]. |
