Biocytin is a conjugate of biotin and lysine known formally as ?-N-(d-biotinyl)-L-lysine. The addition of lysine to biotin increases the chain length extending from biotin, allowing the synthesis of medium-chain reagents. It also provides terminal carboxyl and amino groups for derivatization or conjugation to...

Nucleophosmin is a nucleolar phosphoprotein involved in cell proliferation, cytoplasmic/nuclear shuttle transportation, nucleic acid binding, ribonucleic cleavage, centrosome duplication, and molecular chaperoning. Its activity is dependent on oligomerization at its N-terminal domain, and it is abundantly expressed...
