Predicted band size: 45 kDa
Observed band size: 110 kDa why is the actual band size different from the predicted?
Exposure time: 5 secondsLAMP1 is a glycoprotein. The molecular weight observed is consistent with what has been described in the literature (PMID: 27061067, 15111122).

Predicted band size: 45 kDa
Observed band size: 110 kDa why is the actual band size different from the predicted?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.
