Figure 2: Western Blot analysis. Lane A: Immuno-positive band at 29 kDa apparent molecular mass shows the full length recombinant Fibrillarin protein decorated with anti-His antibody. Bands at 26 kDa and 24 kDa, respectively, show truncations. Lane B: Immuno-positive band at 33 kDa apparent molecular mass shows the full length recombinant RA33 protein decorated with anti-His antibody. Lane C: Immuno-positive band at 33 kDa apparent molecular mass shows the full length recombinant RA33 protein decorated with anti-RA33 mAb. Molecular mass marker positions are indicated on the left (numbers refer to apparent molecular masses in kDa).
