Western blot - Anti-SAA1 + SAA2 antibody [EPR19550] - BSA and Azide free (ab251476)All lanes : Anti-SAA1 + SAA2 antibody [EPR19550] (ab207445) at 1/1000 dilution
Lane 1 : Human SAA1 active recombinant protein
Lane 2 : Human SAA2 fragment recombinant protein
Lane 3 : Human SAA4 fragment recombinant protein
Lysates/proteins at 0.01 µg per lane.
Secondary
All lanes : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/100000 dilution
Predicted band size: 13 kDa
Observed band size: 13,35 kDa why is the actual band size different from the predicted?
Exposure time: 3 minutesThis data was developed using ab207445, the same antibody clone in a different buffer formulation.
Blocking and dilution buffer: 5% NFDM/TBST.
Human SAA2 and SAA4 fragment recombinant protein contain aa19-122 and aa19-130 with His-Tag® and GST-tag.
