  ab191881 was shown to react with Lin28B in wild-type HEK-293 cells in Western blot with loss of signal observed in LIN28B knockout sample. Wild-type HEK-293 and LIN28B knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 3 % milk in TBS-T (0.1 % Tween^®) before incubation with ab191881 and Anti-alpha Tubulin antibody [DM1A] - Loading Control ab7291 (Mouse anti-Alpha Tubulin [DM1A]) overnight at 4°C at a 1 in 2000 dilution and a 1 in 20000 dilution respectively. Blots were incubated with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed (Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed (Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776) secondary antibodies at 1 in 20000 dilution for 1 h at room temperature before imaging.

  ab191881 staining Lin28B in wild-type HEK293 cells (top panel) and Lin28B knockout HEK293 cells (bottom panel). The cells were fixed with 4% paraformaldehyde (10 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab191881 at 10μg/ml and Anti-alpha Tubulin antibody [DM1A] - Loading Control ab7291 (Mouse monoclonal to alpha Tubulin) at 1/1000 dilution overnight at +4°C, followed by a further incubation at room temperature for 1h with a goat secondary antibody to rabbit IgG (Alexa Fluor® 488) (Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed ab150081) at 2 μg/ml (shown in green) and a goat secondary antibody to mouse IgG (Alexa Fluor® 594) (Goat Anti-Mouse IgG H&L (Alexa Fluor® 594) preadsorbed ab150120) at 2 μg/ml (shown in pseudo color red).
