Application examples

Application examples

application example

 Approximately 10 µg of total protein from Y. pseudotuberculosis    extracted with   were separated on 12 % SDS-PAGE and blotted 1h to PVDF. Blots were blocked immediately following  transfer in milk solution (10 % milk powder in TBST) for 1 h at room temperature with agitation. Blots were incubated in the primary antibody at a dilution of 1: 5 000 overnight at  4 °C with agitation. The antibody solution was decanted and the blot was washed twiced for 15 min in TBST at room temperature with agitation. Blots were incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, from GE Healthcare) diluted to 1: 20 000 in  for 1h at room temperature with agitation. The blots were washed as above and developed for 35 min with homemade ECL  detection reagent. Exposure time was 60  seconds.

Additional information

In WB, lower molecular weight cross-reacting bands exist at approximately 34 kDa and 24 kDa, Neither of these interfere with SurA identification,
