The western blot (WB) data displayed is for a recombinant protein of K-ras4A, which also has a GFP tag. The addition of the tag results in the protein being significantly larger (~45kD) than the wildtype or non-tagged protein. The linked article presents testing data of endogenous cell lines using this antibody to detect the protein at the expected size, thus indicating the specificity of the antibody.

Could you explain why the antibody recognizes a band at 45kD instead of the expected 21kD? Also, do you have any proof that the antibody is specific?
