Retrograde tracing experiment:

Rats were anesthetized with a mixture of ketamine …Animals were placed in a Stoelting stereotaxic frame and a hand drill was used to expose the brain surface above the target sites. Iontophoretic injections of 0.5% CTb (List Biologicals, Campbell, CA, USA), which was dissolved in 0.01 M phosphate buffer (PB; pH 7.4), were done by applying a positive current of 1.02.5 A (200 ms pulses at 2 Hz for 15 min) through a chlorinated silver wire placed in a glass pipette (approximately 7µm diameter tip). The coordinates used for injecting CTb were as follows: aPVT at 1.5 mm posterior, 1.0 mm lateral, 5.0 mm ventral, 10 angle toward the middle; and pPVT at 3.0 mm posterior, 0.7 mm lateral, 5.0 mm ventral, 10 angle toward the middle (all coordinates are relative to bregma and the dural surface of the …

To measure tetanus IgG titres and to determine the IgG subclasses, we randomly selected plasma samples from eight paired HbAA and HbAS pairs of children in each age group (3-5, 6-8, and 9-11 years) and tested them at A dilution of 1:500 (n = 48). Tetanus toxoid was purchased from the List biological Laboratories, Inc. (Campbell, CA).

Anti-toxin A/B IgG measurement:

Levels of IgG specific to C. difficile toxin A and toxin B were measured in serum from infected mice. 96-well EIA plates (Corning Incorporated, Tewksbury, MA) were coated with 100l of either purified C. difficile toxin A or toxin B (List Laboratories, Campbell, CA) at 5g/mL in …
