  OI-RD Scanning - Anti-Profilin 1 antibody [EPR6304] - BSA and Azide free (ab232020)

  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.

  Anti-Profilin 1 antibody [EPR6304] ab124904 was shown to react with PFN1 in wild-type HAP1 cells in Western blot with loss of signal observed in a PFN1 knockout cell line. Wild-type HAP1 and PFN1 knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 5% milk in TBST for 1 hr before incubation with Anti-Profilin 1 antibody [EPR6304] ab124904 overnight at 4 °C at a 1/30000 dilution. Blots were incubated with secondary antibodies at 0.2ug/mL before imaging.
