Fresh and frozen xenograft tumors display similar polysome profiles
Fresh and frozen xenograft tumors display similar polysome profiles. Fresh (b, d, f) and frozen (a, c, e) xenograft tumor extracts were separated on a 7–47% sucrose gradient and the absorbance was measured at 254 nm. The fractions corresponding to the polysomes were collected for further RNA extraction
