We used a reducing agent (BME) in Western blot, and there are several bands in the gel. I wonder what sizes could we expect for albumin. Thank you for your answers!
Albumin does not have disulfide bonds, commercial albumin is contaminated with antibodies and transferrin.
Thank you for your answer! So the many bands I got are from contamination? Actually, I can see bands at 100, 80, 60, 50, 42, and 17 kDa.
You should see an intense band around 67 kDa, which is albumin, along with fainter bands of contaminants.
