SNAPtide based LC activity assay:

SNAPtide (o-Abz-Dnp) (List Biological Laboratories) was used for studying the LCs
activity and inhibition (Figure 2.2). 100 M SNAPtide stock was prepared in DMSO.
The proteolytic reaction was initiated by the addition of LC to 20 mM HEPES (pH 7.5)
with 2 M SNAPtide. The protease activity was monitored by the increase of o-Abz
fluorescence (ex: 320 nm, em: 420 nm). The results were analyzed using Sigmaplot. …

Flow cytometry:

… For intracellular cytokine staining, cells were incubated with LPS (100ngml¹) in the presence of GolgiStop (2M; BD Biosciences) for 5h. Surface and intracellular cytokine staining were performed as described elsewhere.²⁵ In some experiments, BM cells were stimulated with LPS (100ngml¹) or Pam3CS(K)4 (100ngml¹) for 24h in the absence or presence of anti-TNF antibody (10gml¹), and were subjected to intracellular cytokine staining.

Cell Culture:

Primary murine tracheal epithelial cells (MTECs) were isolated and cultured … Sixteen hours before treatment, cells were starved in medium containing 0.5% FBS. Cells were exposed to 1 g/ml LPS (List Biological Laboratories, Inc., Campbell, CA), …

Mice

C57Bl/6 mice were anesthetized and received 5 g LPS oropharyngeally (List Biological Laboratories, Inc.), and 24 hours later were killed by pentobarbital injection. The right lobe was flash-frozen in liquid nitrogen and pulverized, and the left lobe was inflated with 4% paraformaldehyde. Five-micron sections were used to assess the localization of RelB in situ via immunofluorescence, …

Plasmids and RNAi:

… Depletion of Rae1 was performed using a double-stranded siRNA oligonucleotide with the sequence 5-CUCAGCAGUAACCAAGCGAUACAGA-3 (Rae1 siRNA; Stealth RNAi; Invitrogen). Cells were incubated with pertussis toxin (181214A1; List Biological Laboratories, Inc.) at 400 ng/ml for 4 h before analysis.

• Product #181 – Pertussis Toxin from B. pertussis, Lyophilized (Salt-Free)

In vitro antibody activity and aggregation assays:

… To monitor ligand-binding activity, an indirect PTx ELISA was employed as reported previously^18,37. High-binding ELISA plates (Costar) were coated with pertussis toxin (PTx, List Biological Laboratories) at 0.75 µg/ml in PBS and incubated at 4°C overnight. …

Demyelination model:

We created relapsing-remitting EAE (R-EAE) from C57Bl/6 mice (Charles-River). Each mouse was immunized subcutaneously (into the flanks) with 100µg of MOG35-55 (MEVGWYRSPFSRVVHLYRNGK), 400 µg of Mycobacterium tuberculosis (strain H37Ra; Difco) in complete Freunds adjuvant (CFA, Difco). One hundred nanogram of Bordetella pertussis toxin (List Biological Laboratories via Cedarlane) was given intravenously at the time of immunization and 2 days later. …

Induction of EAE:

… The A_2AR KO mice were in congenic C57BL/6 background after backcrossing for more than 12 generations (Yu et al. 2005). … To induce EAE, 10 to 12weekold female mice were injected subcutaneously with 200g MOG₃₅₅₅ peptide (AC Scientific, China) emulsified in complete Freunds adjuvant (CFA, containing 8mg/ml Mycobacterium tuberculosis H37Ra). Reconstituted lyophilized pertussis toxin (200ng List Biological Laboratories, Campbell, CA, USA) was injected intraperitoneally immediately after the MOG injection and again 48h later. …
