Meccanismi biochimici e fisiologici
IL-29, also known interferon-lambda 1 (IFN lambda 1), along with IL-28A (IFN lambda 2), IL-28B (IFN lambda 3) and IFN lambda 4, collectively comprise the type III subset of IFNs. IFN lambda s are class II cytokine receptor ligands distantly related to bot

Ricostituzione
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute at 0.1 mg/mL in sterile distilled water. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.

Recombinant Human IL-29/IFN-lambda 1 Protein (rp169632) - SDS-PAGE
3 μg/lane of Recombinant Human IL-29/IFN-lambda 1 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing a band at 25.2 kDa under reducing conditions and 19.5 kDa under non-reducing conditions.
Human IL‑29 (IFN‑λ1), a flexible secreted class II cytokine with exposed loop regions, is prone to N/C‑terminal truncation by host proteases, yielding a minor band 3–5 kDa smaller than the mature protein (PMID: 20712453).

Domande frequenti
What is the purity of this product, and how is it determined?
This product is supplied at ≥90% purity, determined by SDS-PAGE. Lot-specific values are stated on the Certificate of Analysis.
What does Carrier Free mean?
Carrier Free indicates that the material has been processed and tested for specialty industrial processing. Specifications focus on the impurities that affect performance in that application — for example, metal content for electronics, particle size for batteries, refractive index for optics, or moisture content for moisture-sensitive processes.
What is His Tag?
His Tag refers to a recombinant protein product fused with the His affinity tag, suitable for recombinant protein expression and affinity purification. The tag enables one-step affinity purification, immobilization or detection without affecting downstream activity in most cases.
How should this product be stored?
Store at ?20 °C. Avoid repeated freeze–thaw cycles. Aliquot into single-use volumes before freezing.
How is this product shipped?
This product ships in an insulated container with ice pads. Unpack on arrival and transfer it to the storage condition stated above.
What documentation is provided?
Available product documentation, including Certificates of Analysis (COA), Safety Data Sheets (SDS), and specification sheets, is shown in the product document area. Document availability and access follow the current site policy.
