Immunoprecipitation - Anti-SNAP29 antibody [EPR9199] (AB138500)

ab138500 (purified) at 1/20 immunoprecipitating SNAP29 in 10 μg HeLa cell lysate (Lanes 1 and 2, observed at 29 kDa). Lane 3 - Rabbit monoclonal IgG (ab172730). For western blotting, VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/1000 dilution. Blocking buffer and concentration : 5% NFDM/TBST Dilution buffer and concentration : 5% NFDM/TBST

Western blot - Anti-SNAP29 antibody [EPR9199] (AB138500)

Lanes 1-3 : Merged signal (red and green). Green - ab138500 observed at 29 kDa. Red - loading control ab8245 observed at 36 kDa.

ab138500 Anti-SNAP29 antibody [EPR9199] was shown to specifically react with SNAP29 in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab265289 (knockout cell lysate ab257693) was used. Wild-type and SNAP29 knockout samples were subjected to SDS-PAGE. ab138500 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 1000 dilution and 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.
