KLF2

KLF4 as a transcription factor in stem cell differentiation

Krüppel-like factors (KLFs) are evolutionarily conserved zinc finger transcription factors that play a role in cell differentiation, proliferation, and pluripotency.

Nucleolin Antibodies: Knowing When it's Time to Split

Nucleolin is an abundant, 106 kDa nucleolar phosphoprotein that is a major protein in actively dividing cells. The stability of nucleolin is heavily cell proliferation-dependent, as nucleolin antibody studies have shown that degraded forms are relatively abundant in quiescent non-dividing cells, while nonexist in actively dividing cells.
