Product Overview
This rabbit polyclonal antibody targets S-phase kinase-associated protein 2 (gene SKP2) in human, mouse and rat samples and is validated for ICC/IF, IHC and Western blot. The predicted molecular weight is 47.8 kDa; the supplier reports observed bands at 46, 48 kDa.
SKP2 is the F-box protein that gives the SCFSKP2 ubiquitin ligase its substrate specificity. Together with CKS1 it targets phosphorylated p27 (CDKN1B), as well as p21, p57 and other cell cycle regulators, for proteasomal degradation, promoting entry into S phase, and it is widely studied as an oncogenic factor.

Samples with a confirmed band (WB): human 293T cells, human Jurkat cells, human HepG2 cells, human MCF-7 cells, human Hela-WT cells, human Hela-SKP2 KO cells, rat testis tissue, rat C6 cells, mouse testis tissue, mouse NIH/3T3 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% 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 cervical 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 8.0).
Immunogen
Synthetic peptide from the C-terminal region of human SKP2. Sequence identity with the mouse and rat orthologs: 88.9% and 94.4%, respectively.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places S-phase kinase-associated protein 2 in the cytoplasm and nucleus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
