• Product #179A – Pertussis Toxin from B. pertussis (in Glycerol)

Reagents:

…Escherichia coli LPS 0111:B4 obtained from…List Biological Laboratories (Campbell, CA) was used for studies involving human PBMCs and mice,…

Human PBMCs and Cytokine Induction by LPS:

PBMCs from healthy human subjects were prepared under a Hebrew University Institutional Review Boardapproved protocol described elsewhere [3, 8] and were cultured at 1 10⁶ cells/mL in Roswell Park Memorial Institute 1640 medium [3, 8]. Cells were allowed to rest at 37C in 5% CO₂ for 4 hours. After LPS stimulation of cells in the presence or absence of AB103/p2TA, culture medium was collected at intervals for triplicate evaluation of cytokines by an enzyme-linked immunoassay (ELISA) [3, 8].

LPS Challenge:

CD1 or BALB/c mice were administered 20 mg D-galactosamine (D-galN) intraperitoneally, followed in 2 hours by 0.25 mg/kg E. coli 0111:B4 LPS. AB103 was injected intraperitoneally 30 minutes before LPS.

Chronic EAE immunization:

Preparations of 200-g MOG₃₅₅₅ peptide emulsified in CFA… were injected subcutaneously into the lower flanks of 8-week-old female C57BL/6J mice (Jackson Laboratory, Bar Harbor, MN). Two intraperitoneal (i.p.) injections of 400-ng pertussis toxin each (no. 181, List Biological Laboratories,…)

ANIMAL EXPERIMENTS:

…At 3 weeks post infection, EAE induction treatment was commenced: mice were immunized via sub-cutaneous injection at two sites with MOG peptide MOG_35-55…, containing 4 mg/ml Mycobacterium tuberculosis H37 Ra… An intraperitoneal injection of 200 ng pertussis toxin (List Biological Laboratories Inc., Campbell, CA, USA) was also administered on the same day, with a second subsequent dose 2 days later. …

Induction, clinical evaluation and treatment protocols of EAE:

… EAE was induced by MOG₃₅₅₅ in female mice used between 8 and 10 weeks of age. Briefly, each mouse was immunized subcutaneously with 300µg of MOG₃₅₅₅ emulsified with an equal volume of complete Freund’s adjuvant…and then injected to the caudal vein with 200ng of pertussis toxin (PTX) (dissolved in 200µl PBS, List Biological Laboratories, USA) at the time of immunization and 2 days later.

Dorsal column transection with sciatic nerve conditioning lesion:

… Five days before tissue collection, the left sciatic nerve was exposed again and 1.5 l of 10 mg/ml cholera toxin subunit (CT; List Biological Laboratories), a trans-ganglionic tracer, was injected into the proximal nerve section using a pulled glass capillary tube pipette.

For immunohistochemical analyses of tracer-labeled regenerated axons, a series of every second section of the T4T9 spinal cord segments (1116 sections per mouse, 100 m apart) was processed for CT immunoreactivity, with the starting section number chosen for each mouse at random. Individual sections were washed,…and incubated in goat anti-CT (List Biological Laboratories, 1:8000) for 15 h.

EAE:

Experiments were performed on adult L71.8TG mice [6] or their wildtype littermates bred in-house…The mice also received an intraperitoneal injection of 500 ng pertussis toxin (List Biological Labs) in 200 µl 0.1M phosphate-buffered saline immediately after the first immunization with MOG and again 48 h later.
