| 背景 | IL-33 (interleukin 33; also NF-HEV and IL-1F11) is a 31-32 kDa member of the IL-1 family of proteins. It is expressed in endothelial cells and reportedly has two functions; first, it induces Th2-type cytokines, and second, it acts as a nuclear transcription factor. Human IL-33 is 270 amino acids (aa) in length. It contains a putative proregion (aa 1-111) and a mature segment (aa 112-270). The proregion contains a bipartite NLS (aa 61-78), plus an alpha -helical homeodomain-like HTH motif (aa 1-65). The HTH motif mediates nuclear localization and heterochromatin association. A potential caspase 1 cleavage site exists in human IL-33 (Ser111-Ser112), but not in IL-33 from canine, porcine or bovine. There is one splice variant that shows a deletion of aa 113-118. Over aa 1-111, human IL-33 propeptide is 45% aa identical to mouse IL-33 propeptide. |

Detection of Human IL‑33 Propeptide by Western Blot. Western blot shows lysates of Jurkat human acute T cell leukemia cell line, Raji human Burkitts lymphoma cell line, and K562 human chronic myelogenous leukemia cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human IL‑33 Propeptide Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4810) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for IL‑33 Propeptide at approximately 31 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8. | |
IL‑33 in HUVEC Human Cells. IL‑33 was detected in immersion fixed HUVEC human umbilical vein endothelial cells using Goat Anti-Human IL‑33 Propeptide Antigen Affinity‑purified Polyclonal Antibody (Catalog # AF4810) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (yellow; Catalog # NL001) and counterstained with DAPI (blue).
