Product Overview
This rabbit polyclonal antibody detects serine/threonine-protein kinase RIO2 (gene RIOK2) in human samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 63.3 kDa, and the supplier reports an observed band at about 63 kDa.
RIOK2 is an atypical RIO-family kinase involved in late maturation of the small (40S) ribosomal subunit. It supports nuclear export of pre-40S particles and, through its kinase activity, the release of assembly factors and final 18S rRNA processing in the cytoplasm, making it a subject of ribosome biogenesis research.

Samples with a confirmed band (WB): human U251 cells, human HeLa cells, human HepG2 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with a confirmed signal (flow cytometry): HL-60 cells.
Immunogen
Recombinant human RIOK2 fragment (Asp16–Leu283), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places serine/threonine-protein kinase RIO2 in the cytoplasm. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
