ING1 in HeLa Human Cell Line. ING1 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using 10 µg/mL Goat Anti-Human ING1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5758) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red, upper panel; Catalog # NL001) and counterstained with DAPI (blue, lower panel).

ING1 in Human Lung Cancer Tissue. ING1 was detected in immersion fixed paraffin-embedded sections of human lung cancer tissue using 5 µg/mL Goat Anti-Human ING1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5758) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Detection of Human ING1 by Western Blot. Western blot shows lysates of A549 human lung carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human ING1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5758) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for ING1 at approximately 28 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

ING1 (Inhibitor of Growth 1; also p33ING1b and ING1A) is a 32 kDa member of the ING family of tumor suppressors. It is very widely expressed, and participates in multiple cell functions. When bound to p53, ING1 inhibits cell growth; when complexed to GADD45, ING1 enhances DNA nucleotide excision repair; and when associated with HAT, ING1 promotes hyperacetylation of histones H3 and H4. Human ING1 is 279 amino acids (aa) in length. It contains a PIP-PBD region (aa 5‑45), an NLS (aa 142‑158), and a plant homeodomain (PHD) (aa 210‑259). Phosphorylation occurs on Ser126 and Ser199. There are at least three isoform variants. p47ING1a contains a 190 aa substitution for aa 1‑46, p27ING1d shows a deletion of aa 2‑45, and p24ING1c has an alternate start site at Met70. Over aa 213‑327, human ING1 shares 82% aa identity with mouse ING1.
