A list of the 33 proteins assayed and the known primary function of each is shown in Table 1. Selection of these 33 proteins was based on the pathways involved in the known inflammatory and radiation-induced damage responses summarized in Table 2. A Bio-Rad protein assay was run for each tissue type (plasma, intestine, bone marrow) and experimental group [9.25 Gy irradiation only (control); 9.25 Gy with JP4-039; 9.25 Gy with necrostatin-1; and 9.25 Gy with JP4-039 at 24 h and necrostatin-1 at 72 h after TBI, as well as other delivery times for the 2 drugs] using a Biotek® Epoch™ Microplate Spectrophotometer (BioTek Instruments Inc., Winooski, VT). We utilized the TGF β1 Single Plex Magnetic Bead Kit, as well as the 32-Multiplex Mouse Cytokine/Chemokine Magnetic Bead Panel (EMD Millipore, Billerica, MA) that tested protein concentrations for eotaxin, G-CSF, GM-CSF, IFN-γ, IL-1α, IL-1β, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, IL-9, IL-10, IL-12 (p40), IL-12 (p70), IL-13, IL-15, IL-17, IP-10, KC, LIF, LIX, MCP-1, M-CSF, MIG, MIP-1α, MIP-1β, MIP-2, regulated upon activation normal T cell expressed and secreted (RANTES), TNF-α and VEGF.
Each kit (MCYTOMAG-70K and TGFBMAG-64K-01) provided reagents for use in the Luminex Protein Immunoassay, which included one vial of mouse cytokine/chemokine standard, two vials mouse cytokine/chemokine quality controls, one vial serum matrix, 96-well plate, 30 ml assay buffer, 60 ml 10× wash buffer, one 3.2-ml bottle of mouse cytokine detection antibodies and one 3.2-ml bottle of streptavidin-phycoerythrin. The 32-Multiplex Kit (MCYTOMAG-70K) provided one 3.5-ml pre-mixed 32-plex beads. The TGF β1 kit (TGFBMAG-64K-01) provided the above reagents, as well as 5 ml sample diluent, 1.0 ml 1.0 N HCl, 1.0 ml 1 N NaOH and 3.5 ml anti-TGF-β1 beads.
