FIGURE 5. Characterization of soluble recombinant Thy-1 with 6 histidine epitope tag at C-terminus.
(A) Mature Thy-1 detected by western blot in the CE of NHLF or CM containing sTHY1 – 6X HIS prepared as indicated under NR conditions or with 2.5% β-mercaptoethanol (β). After stripping the membranes of antibodies for detecting mature Thy-1, the 6X HIS epitope tag was probed for. (B) 6X HIS epitope detected by western blot in equal dilutions of untreated or PNGase F treated CM containing sThy-1 – 6X HIS.
