Product Overview
This rabbit polyclonal antibody targets cAMP-dependent protein kinase inhibitor beta (gene PKIB) in human samples and is validated for IHC and ELISA. The predicted molecular weight is 8.5 kDa.
PKIB is a member of the PKI family of small, heat-stable inhibitors of cAMP-dependent protein kinase (PKA). It binds the free PKA catalytic subunit after cAMP releases the regulatory subunits, blocking its kinase activity and tuning cAMP signaling.
| Target | CAMP-dependent protein kinase inhibitor beta (gene PKIB; UniProt Q9C010, human) |

| Host / Clonality / Isotype | Rabbit / Polyclonal / Rabbit IgG |
| Reactivity | Human |
| Form | Lyophilized |
| Formulation | Per vial: 4 mg trehalose; 0.9 mg NaCl; 0.2 mg Na2HPO4 |
| Calculated MW | 8.5 kDa |
| Storage | As supplied: −20 °C for up to 12 months from receipt. After reconstitution: 4 °C for up to 1 month, or aliquot and keep at −20 °C for up to 6 months. Avoid repeated freeze–thaw cycles. |
Validated Applications
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
|---|---|
| ELISA | 0.1–0.5 µg/mL |
Samples with confirmed staining (IHC): human placenta 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 8.0).
Immunogen
Recombinant human PKIB fragment (Met1–Lys78), expressed in E. coli.

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).
