Detection of Human Importin alpha 3/KPNA4 by Western Blot.
Western blot shows lysates of NTera‑2 human testicular embryonic carcinoma cell line and HeLa human cervical epithelial carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human Importin alpha 3/KPNA4 Monoclonal Antibody (Catalog # MAB8204) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Importin alpha 3/KPNA4 at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of Human Importin alpha 3/KPNA4 by Simple WesternTM.
Simple Western lane view shows lysates of HeLa human cervical epithelial carcinoma cell line, loaded at 0.5 mg/mL. A specific band was detected for Importin alpha 3/KPNA4 at approximately 56 kDa (as indicated) using 10 µg/mL of Mouse Anti-Human Importin alpha 3/KPNA4 Monoclonal Antibody (Catalog # MAB8204). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system. Non-specific interaction with the 230 kDa Simple Western standard may be seen with this antibody.

Background: Importin alpha 3/KPNA4
KPNA4 (Karyopherin subunit alpha 4), also called Importin subunit a4 or Importin aQ1 (previously called Qip1 or Importin a3) is an approximately 58-60 kDa member of the Importin alpha family of proteins. It is ubiquitously expressed, and found in both nucleus and cytoplasm. KPNA4 functions as a cargo carrier that transports various complexes from cytoplasm into nucleus. Human KPNA4 is a 521 amino acid (aa) protein that contains an N-terminal IBB/Importin b domain (aa 2-58), ten Armadillo repeats that bind “cargo” (aa 66-485) and two intervening NLS binding sites. Human KPNA4 aa 1-104 share 99% aa identity with mouse and rat KPNA4, which in turn share 100% identity with each other.
