Western blot - Anti-IKK beta antibody [EPR6043] - BSA and Azide free (AB171364)

This WB data was generated using the same anti-IKK beta antibody clone [EPR6043] in a different buffer formulation (cat# ab124957).

Lane 1 : Wild-type HAP1 cell lysate (20 μg)
Lane 2 : IKK beta knockout HAP1 cell lysate (20 μg)
Lanes 1 and 2 : Merged signal (red and green). Green - ab124957 observed at 90 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab124957 was shown to specifically react with IKK beta when IKK beta knockout samples were used. Wild-type and IKK beta knockout samples were subjected to SDS-PAGE. ab124957 and ab8245 (loading control to GAPDH) were diluted 1/500 and 1/2000 and incubated overnight at 4°C. 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 1/10,000 dilution for 1 h at room temperature before imaging.

Western blot - Anti-IKK beta antibody [EPR6043] - BSA and Azide free (AB171364)

This data was developed using the same antibody clone in a different buffer formulation (ab124957).

Lanes 1- 2 : Merged signal (red and green). Green - ab124957 observed at 90 kDa. Red - Anti-GAPDH antibody [6C5] - Loading Control (ab8245) observed at 37 kDa.

ab124957 was shown to react with IKK beta in wild-type HeLa cells in western blot. The band observed in CRISPR/Cas9 edited cell line ab264847 (CRISPR/Cas9 edited cell lysate ab257228) lane below 90kDa may represent truncated forms and cleaved fragments. This has not been investigated further. Wild-type HeLa and IKBKB CRISPR/Cas9 edited HeLa 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. ab124957 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at a 1 in 500 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.

We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody. Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.
