Figure Lengend Snippet: SDS-DNA PAGE of IF cells of H. obtusa . P. caudatum DNA was used. ( a ) CBB stained gel. ( b ) Immunoblot with mAb3D1B9C4 specific for PRP1. ( c ) EB stained gel. Arrows, 63-kDa PRP1. It should be noted that not only PRP1 but also many EB-negative bands that show the positions of DNA-protein complexes appeared (see ).

Article Snippet: For SDS–DNA PAGE, a 10% ( w / v ) separation gel containing 10 μg mL –1 calf thymus DNA (Worthington Biochemical Corp., Lakewood, NJ, USA) or 10 μg mL –1 P. caudatum whole genome DNA was used.

Techniques: IF-cells, Staining, Western Blot

Figure Lengend Snippet: DNA affinity chromatography of H. obtusa IFs. P. caudatum DNA was used. ( a ) Silver stained SDS-PAGE gel; ( b ) immunoblotting with the monoclonal antibody mAb3D1B9C4 specific for the 63-kDa periplasmic protein PRP1 of H. obtusa . Lane 1, supernatant of sonicated H. obtusa before applying to DNA affinity chromatography column; lane 2, first elute of supernatant of sonicated H. obtusa after applying to the column; lane 3, first elute by elution buffer containing 0.02 M NaCl; lane 4, first eluate by 0.1 M NaCl elution buffer; lane 5, first eluate by 0.2 M NaCl elution buffer; lane 6, first eluate by 0.3 M NaCl elution buffer; lane 7, first eluate by 2 M NaCl elution buffer; arrows, PRP1. Eluates from each column were collected in every 200 μL, and the first eluate from each column was used for SDS-PAGE and immunoblot with mAb. Note that not only PRP1 but also several silver stained bands were confirmed in lane 4 of ( a ).
