hello,
am looking for a protein of nearly 35 kDa via Western blot for which i use specific antibody...this time when i performed western, apart from this band (which was weak) i saw a dark band of about 60 kDa..the antibody is said to be specific...does anyone know how to account for this?

could be an artifact which shows up when using aged 2-mercaptoethanol (and dust). it will stain non-specifically.
