Western blot - Anti-LAMP1 antibody [EPR4204] - Lysosome Marker (AB108597)

Lanes 1 - 4 : Merged signal (red and green). Green - unpurified ab108597 observed at 110 kDa. Red - loading control, ab18058, observed at 130 kDa.

ab108597 was shown to recognize LAMP1 in wild-type HAP1 cells as signal was lost at the expected MW in LAMP1 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and LAMP1 knockout samples were subjected to SDS-PAGE. ab108597 and ab18058 (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 1/10000 dilution for 1 hour at room temperature before imaging.

Western blot - Anti-LAMP1 antibody [EPR4204] - Lysosome Marker (AB108597)

Western blot : Anti-LAMP1 antibody [EPR4204] - Lysosome Marker staining at 1/1000 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab108597 was shown to bind specifically to LAMP1. A band was observed at 100-120 kDa in wild-type HCT 116 cell lysates with no signal observed at this size in LAMP1 knockout cell line. To generate this image, wild-type and LAMP1 knockout HCT 116 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.
