Blots were also probed with antibodies specific for the bacterium’s immunodominant outer membrane protein 56 kDa type-specific antigen (TSA56) as an infection control, heat shock protein 90 (Hsp90) or glyceraldehyde-3-phosphate dehydrogenase (GAPDH) as a cytoplasmic fraction loading control, and lamin A/C as a nuclear fraction loading control. This evidence concerns the gene GAPDH and infection.
