Mecanismos bioquímicos y fisiológicos
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

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).
