Western blot - Anti-PI 3 Kinase p85 alpha antibody [EPR5513] (AB133595)

Lane 1 : Wild-type HAP1 cell lysate (20 μg)
Lane 2 : PI 3 Kinase p85 alpha knockout HAP1 cell lysate (20 μg)
Lane 3 : Jurkat cell lysate (20 μg)
Lane 4 : THP1 cell lysate (20 μg)
Lanes 1 - 4 : Merged signal (red and green). Green - ab133595 observed at 90 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab133595 was shown to specifically react with PI 3 Kinase p85 alpha when PI 3 Kinase p85 alpha knockout samples were used. Wild-type and PI 3 Kinase p85 alpha knockout samples were subjected to SDS-PAGE. ab133595 and ab8245 (loading control to GAPDH) were diluted 1/1000 and 1/2000 respectively 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 1/10000 dilution for 1 h at room temperature before imaging.

Lanes 1- 2 : Merged signal (red and green). Green - ab133595 observed at 90 kDa. Red - Anti-GAPDH antibody [6C5] - Loading Control (ab8245) observed at 37 kDa.

ab133595 was shown to react with PI 3 Kinase p85 alpha in wild-type HeLa cells in western blot. Loss of signal was observed when knockout cell line ab265116 (knockout cell lysate ab257029) was used. Wild-type HeLa and PIK3R1 knockout 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. ab133595 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) overnight at 4°C at a 1 in 1000 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.
