All lanes : Anti-NFkB p100/NFKB2 antibody [EPR4686-66] (ab175192) at 1/1000 dilution

Lane 1 : Wild-type HepG2 cell lysate
Lane 2 : NFKB2 knockout HepG2 cell lysate

Lysates/proteins at 20 µg per lane.

Performed under reducing conditions.

Predicted band size: 97 kDa
Observed band size: 120 kDa why is the actual band size different from the predicted?

Lanes 1- 2: Merged signal (red and green). Green - ab175192 observed at 120 kDa. Red - Anti-GAPDH antibody [6C5] - Loading Control (ab8245) observed at 37 kDa.

 ab175192 was shown to react with NFkB p100/NFKB2 in wild-type HepG2 cells in western blot. The band observed in knockout cell line ab262323 (knockout cell lysate ab257247) lane below 97kDa may represent truncated forms and cleaved fragments. This has not been investigated further. Wild-type HepG2 and NFKB2 knockout HepG2 cell lysates were subjected to SDS-PAGE. Membrane was blocked for 1 hour at room temperature in 0.1% TBST with 3% non-fat dried milk. ab175192 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at a 1 in 10000 dilution and a 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^®800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^®680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.
