Purity:Purified by Protein A affinity chromatography.
Form:Supplied as a liquid in PBS, pH 7.2, 0.09% sodium azide and a stabilizer. Labeled with Allophycocyanin (APC).
Specificity:Recognizes a cell-cycle-associated protein of 345kD and 395kD identical with the human Ki-67 antigen. Binds to a formalin-resistant epitope of the Ki-67 antigen. Reactivity is confined to the nuclei of proliferating cells and no crossreactivity with cytoplasmic antigens of epithelial occurs even after antigen retrieval. Immunohistochemistry labeling of fresh and frozen samples showed identical results with Ki-67 and Ki-S5.
Clone # USB:2Q476 (Ki-S5)
Isotype:IgG1
Calc Applications Abbrev:IC IHC WB
Calc Crossreactivity:Hu
Immunogen:Nuclear protein preparation from the human cell line U937.50.
