Product Overview
This rabbit polyclonal antibody targets receptor-interacting serine/threonine-protein kinase 2 (gene RIPK2) in human samples and is validated for Western blot, IHC, flow cytometry and ELISA. The predicted molecular weight is 61.2 kDa, and the supplier reports an observed band at about 61 kDa.
RIPK2 (also called RICK) is a kinase that relays signals from the bacterial peptidoglycan sensors NOD1 and NOD2. After recruitment through CARD–CARD interactions it is ubiquitinated and triggers NF-κB and MAPK activation, leading to inflammatory cytokine production, so it is studied in innate immunity and inflammatory bowel disease.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human) |
|---|---|
| IHC (paraffin sections) | 5 µg/mL (Human, Mouse) |
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Human) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human K562 cells, human PC-3 cells, human Daudi cells, human T-47D cells, human U251 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 confirmed staining (IHC): human colon tissue, human colon cancer tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8).
Samples with a confirmed signal (flow cytometry): Caco-2 cells.
Immunogen
Recombinant human RIP2/RIPK2 fragment (Tyr15–Met540), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places receptor-interacting serine/threonine-protein kinase 2 in the cytoplasm, cell membrane and endoplasmic reticulum. Tissue expression noted by UniProt (human): Detected in heart, brain, placenta, lung, peripheral blood leukocytes, spleen, kidney, testis, prostate, pancreas and lymph node. 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).
