We are seeking a candidate interested in understanding transport and function of cholesterol in the sterol-auxotroph organism Caenorhabditis elegans.
Pechous RD, McCarthy TR, Mohapatra NP, Soni S, Penoske RM, et al. (2008) A Francisella tularensis Schu S4 purine auxotroph is highly attenuated in mice but offers limited protection against homologous intranasal challenge.
From this strain we generated a Ura − auxotroph (strain SCMSP202) by plating on solid media containing 5-Fluoroorotic Acid (5-FOA).
