Product Overview
This rabbit polyclonal antibody targets suppressor of SWI4 1 homolog (gene PPAN) in human samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 53.2 kDa, and the supplier reports an observed band at about 65 kDa.
PPAN, also called SSF1 or Peter Pan homolog, is a nucleolar protein of the Brix domain family. By similarity to its yeast and fly counterparts it is thought to take part in ribosome biogenesis and support cell growth, though its function in human cells is not fully characterized.
