• Product #104 – Cholera Toxin B Subunit (Choleragenoid) from Vibrio cholerae in Low Salt

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 …

MOG-induced EAE: active induction of EAE

… C57BL/6J and Gas6^/ mice were immunized with MOG_35-55 peptide. MOG_35-…Mice were anesthetized with isoflurane and 100 µl of emulsion was injected subcutaneously on each flank (200 µl total/mouse) on day 0. In addition, 200 µl of pertussis toxin (Ptx, 2.5 µg/ml; List Biological Laboratories) was injected intraperitoneally on days 0 and 2. …

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 …

Maternal protocol

To establish maternal peanut allergy, female C3H/HeJ mice, on a peanut free diet, were orally sensitized with peanut as previously described(15;16) with slight modification. Briefly, 6 week-old female mice were sensitized with peanut (10 mg PN) and cholera toxin (20 μg CT) intragastrically (i.g.) weekly for 5 weeks (wks) and challenged at wk 6 (200 mg PN/mouse). Our sensitization protocol differed from our previous standard protocol in that mice did not receive an additional boost (50 mg PN+10 mg CT). …
