Product Overview
This rabbit polyclonal antibody recognizes ribosomal protein S6 kinase alpha-2 (gene RPS6KA2) in human, mouse and rat samples and is validated for ELISA, ICC/IF, IHC and Western blot. The predicted molecular weight is 83.2 kDa, and the supplier reports an observed band at about 90–100 kDa.
RSK3 (RPS6KA2) is a p90 ribosomal S6 kinase family member activated downstream of ERK1/2. Like other RSKs it has two kinase domains and phosphorylates transcription factors and translation regulators, and it has been proposed as a tumor suppressor in ovarian cancer 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, 50 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 1:10000, ECL detection.
Immunogen
Recombinant human RSK3 fragment (His658–Leu733), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places ribosomal protein S6 kinase alpha-2 in the nucleus and cytoplasm. Tissue expression noted by UniProt (human): Widely expressed with higher expression in lung, skeletal muscle, brain, uterus, ovary, thyroid and prostate. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
