Western blot - Anti-LAMP2 antibody [EPR19531] - Lysosome Marker (AB199947)

Lanes 1 - 4 : Merged signal (red and green). Green - ab199947 observed at 45 kDa. Red - loading control, ab130007, observed at 130 kDa.

ab199947 was shown to specifically react with LAMP2 in wild-type HEK-293 cells as signal was lost in LAMP2 knockout cells. Wild-type and LAMP2 knockout samples were subjected to SDS-PAGE. ab199947 and ab130007 (Mouse anti-Vinculin loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

Western blot - Anti-LAMP2 antibody [EPR19531] - Lysosome Marker (AB199947)

False colour image of Western blot : Anti-LAMP2 antibody [EPR19531] staining at 1/1000 dilution, shown in green; Mouse anti-Alpha Tubulin [DM1A] (ab7291) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab199947 was shown to bind specifically to LAMP2. A band was observed at 100 kDa in wild-type HeLa cell lysates with no signal observed at this size in LAMP2 CRISPR-Cas9 edited cell line ab255402 (CRISPR-Cas9 edited cell lysate ab263861). The band observed in the CRISPR-Cas9 edited lysate lane below 100 kDa is likely to represent a truncated form of LAMP2. This has not been investigated further and the functional properties of the gene product have not been determined. To generate this image, wild-type and LAMP2 CRISPR-Cas9 edited HeLa cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.
