Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Detection of Human, Mouse, and Rat Importin beta /KPNB1 by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line, NIH-3T3 mouse embryonic fibroblast cell line, and Rat-2 rat embryonic fibroblast cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human Importin beta /KPNB1 Monoclonal Antibody (Catalog # MAB8209) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Importin beta /KPNB1 at approximately 97 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Importin beta /KPNB1 in HeLa Human Cell Line. Importin beta /KPNB1 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Mouse Anti-Human Importin beta /KPNB1 Monoclonal Antibody (Catalog # MAB8209) at 25 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to nuclei.

Background: Importin beta/KPNB1
KPNB1 (Karyopherin subunit beta 1), also called Importin beta 1, NTF97 (nuclear transport factor, 97 kDa) or PTAC97 (pore targeting complex, 97 kDa), is a member of the Importin b family of proteins. It is ubiquitously expressed and plays many roles in the nucleus. Primarily, KPNB1 transports various complexes from cytoplasm into nucleus, either alone or with a KPNA adaptor. The 876 amino acid (aa) human KPNB1 contains an N-terminal IBB/Importin b domain (aa 21-101), and eight HEAT (solenoid) domains (aa 124-726). A 731 aa splice variant begins with Met146, while an 845 aa variant shows a 2 aa substitution for aa 702-734. Binding sites for adaptors and for its regulator, Ran-GTP, overlap within the HEAT domains. Human KPNB1 aa 1-155 shares 99% and 97% aa sequence identity with mouse and rat KPNB1, respectively.
