Human KPNA4 (Karyopherin subunit alpha-4) ELISA Kit (HUFI03671)

KPNA4 encodes importin subunit alpha-3 (also called QIP1), a nuclear transport receptor that recognizes classical nuclear localization signals and ferries cargo proteins through the importin-beta pathway into the nucleus.

Produced by Assay Genie, this research-use ELISA kit enables investigators studying HIV-1 integration mechanisms, STAT1 nuclear translocation, or tumor-cell signaling cascades to quantify endogenous KPNA4 expression in human research samples.

The microplate-based workflow relies on a biotinylated detection antibody with streptavidin-HRP signal generation and includes a standard curve of recombinant human KPNA4 protein for quantitative interpolation of unknown sample concentrations.

Each assay pack contains a pre-coated plate, lyophilized standards, biotinylated detection reagent, assay diluent, wash concentrate, substrate solution, and stop solution, sufficient for the full plate of samples run in duplicate.

For handling, keep unopened components refrigerated, avoid repeated freeze-thaw cycles of the reconstituted standard, and protect the enzyme conjugate from light to preserve activity throughout the shelf life of the kit.
