Nucleostemin Antibody [Unconjugated] Summary

E. coli-derived recombinant rat Nucleostemin
Accession # Q811S9
Detects human, mouse, rat Nucleostemin in direct ELISAs and Western blots. In direct ELISAs, less than 1% cross-reactivity with recombinant rat Nucleostemin C-terminal peptide (aa 281-538) is observed. Rat Nucleostemin specific IgG was purified by first passing the sera over a rat Nucleostemin aa 2-538 column and then passing the bound fraction over a rat Nucleostemin aa 281-538 column to removed rat Nucleostemin C-terminal specific IgG.

Nucleostemin is a protein found in the nucleoli of embryonic stem cells, adult CNS stem cells, primitive cells in the bone marrow and cancer cells. It is not in the differentiated cells of most adult tissues. It has been suggested to play a role in controlling the cell-cycle progression in stem cells and cancer cells (1-3).
