Product Overview
This rabbit polyclonal antibody targets cyclin-dependent kinase 5 (gene CDK5) in human, mouse and rat samples and is validated for Western blot, IHC and ELISA. The predicted molecular weight is 33.3 kDa, and the supplier reports an observed band at about 33 kDa.
CDK5 is an atypical cyclin-dependent kinase that is activated not by cyclins but by p35 or p39, which are enriched in neurons. It regulates neuronal migration, axon growth and synaptic function, and abnormal CDK5 activity is studied in neurodegeneration, including tau phosphorylation in Alzheimer′s disease models.

|---|---|
| IHC (paraffin sections) | 0.5–1 µg/mL |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human SH-SY5Y cells, rat brain tissue, mouse brain tissue.
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 brain tissue, human mammary cancer tissue, human rectal cancer tissue, mouse intestine tissue, rat intestine tissue, rat brain 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 CDK5 fragment (Met1–Gln226), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. Tissue expression noted by UniProt (human): Ubiquitously expressed. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
