Product Overview
Clone GIC-3 is a rabbit monoclonal antibody that recognizes cyclin-dependent kinase 4 (gene CDK4) in human samples and is validated for Western blot, IHC, ICC/IF and flow cytometry. The predicted molecular weight is 33.7 kDa, and the supplier reports an observed band at about 34 kDa.
CDK4 is a serine/threonine kinase that partners with D-type cyclins to phosphorylate the retinoblastoma protein RB1 in G1 phase. This releases E2F transcription factors and commits the cell to enter S phase, which is why CDK4 and its inhibitors are central topics in cell cycle and cancer research.

Samples with confirmed staining (IHC): human stomach cancer tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Samples with confirmed staining (ICC/IF): MCF-7 cells.
Immunogen
Synthetic peptide based on the sequence of human CDK4.
Reactivity Notes
The supplier lists reactivity with human. UniProt places cyclin-dependent kinase 4 in the cytoplasm, nucleus and nuclear membrane. 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).
