Figure 2. Immunodetection of lactoferrin protein in transgenic calli.
Total protein extract from the transgenic calli was fractionated by
SDS-PACE and stained with Coomassie blue (A) or blotted onto a
nitrocellulose membrane and probed with a commercially available
anti-lactoferrin antibody reagent (B). Numbers at the right are
protein size markers in kD. Lane M, Marker; lane CL, commercially
available lactoferrin; lanes T1 to T5, protein extracts from transgenic
tobacco calli; lane TC, protein extract from control tobacco
calli; PL, immunoreactive lactoferrin protein bands from transgenic
