Product Overview
Clone IAH-3 is a rabbit monoclonal antibody that recognizes sororin (gene CDCA5) in human samples and is validated for Western blot, IHC, ICC/IF and flow cytometry. The predicted molecular weight is 27.6 kDa, and the supplier reports an observed band at about 35 kDa.
Sororin (CDCA5) is a cohesin regulator that stabilizes sister chromatid cohesion after DNA replication by counteracting the release factor WAPL. It ensures that sister chromatids stay paired until mitosis, supporting accurate chromosome segregation and DNA repair.

Samples with a confirmed band (WB): human K562 cells, human U2OS 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 1:500 overnight at 4 °C, HRP-conjugated secondary antibody at 1:500, ECL detection.
Samples with confirmed staining (IHC): human colon 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): HeLa cells.
Immunogen
Synthetic peptide based on the sequence of human CDCA5.
Reactivity Notes
The supplier lists reactivity with human. UniProt places sororin in the nucleus, chromosome and cytoplasm. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
