A mixture of Mima-8 and Mima-9, which recognizes Kpb epitopes on the K1 transgene, was used to evaluate K1 expression by KEL1A and K1 mice. Platelet-rich plasma was generated by centrifuging peripheral blood at 8000 g for ten min. For evaluation of dendritic cells (DCs), spleens were minced having a razor blade and filtered by way of one hundred m Nylon mesh prior to RBC lysis. Single-cell suspensions were stained with fluorescently conjugated Abs distinct for cellsurface proteins, such as CD19 (Clone: 6D5), TCR (H57-597), and I-A/I-E [MHC class II (MHCII), M5/114.15.2], CD86 (GL-1), Ly6C (HK1.4) and F4/80 (BM8) from BioLegend (San Diego, CA); CD45.1 (A20), CD11c (N418), CD11b (M1/70), CD8 (53-6.7), Ter-119, and Siglec H (eBio440c) from eBioscience (San Diego, CA), and CD41 (MWReg30) from BD Biosciences (San Jose, CA). Zombie-NIR (BioLegend) was made use of to exclude dead cells. Cells were acquired having a Miltenyi MACSQuant flow cytometer and analyzed working with FlowJo. Generation of bone marrow chimeras Recipient WT C57BL/6 (CD45.Androgen receptor Protein site 2+) and Ifnar1-/- (CD45.TGF beta 2/TGFB2 Protein Purity & Documentation 2+) mice had been exposed twice to xray irradiation (6.35 Gy, three h apart) applying an X-RAD 320 irradiator (Precision X-ray, North Branford, CT). Recipients were injected i.v. with 3 106 bone marrow cells from WT C57BL/6-Ly5.1 (CD45.1+) or Ifnar1-/- mice 2 h just after irradiation. Peripheral blood was analyzed for lymphocyte reconstitution 6 wk just after bone marrow transfer. CD45.1 and CD45.two congenic markers have been used to determine the supply of reconstituted cells. Mice have been transfused eight wk following bone marrow reconstitution. Measurement of IFN-/ Serum IFN- was measured by ELISA as previously described (59). For mRNA measurement, splenocytes had been enriched for DCs using a mouse pan-DC enrichment kit (19763; Stemcell Technologies, Vancouver, BC). Enrichment was examined by flow cytometry. mRNA was isolated having a Qiagen RNEasy MiniKit (Valencia, CA), treated with DNAse, and reverse-transcribed using a Roche Applied Sciences kit (Indianapolis, IN). cDNA was quantitated using a KAPA SYBR Fast qPCR kit (KAPA Biosystems, Wilmington, MA), making use of a Stratagene Mx3000P instrument.PMID:23618405 Primers for Ifn4 and Ifn are: Ifn4 forward, 5-CTG CTA CTT GGA ATG CAA CTC-3; Ifn4 reverse, 5-CAG TCT TGC CAG CAA GTT GG-3; Ifn forward, 5-GCA CTG GGT GGA ATG AGA CTA TTG-3; Ifn reverse, 5-TTC TGA GGC ATC AAC TGA CAG GTC-3. Western blot evaluation Peripheral blood cells from K1 and C57BL/6 WT mice had been lysed using hypotonic sodium phosphate. Samples were reduced, electrophoresed on a polyacrylamide gel, and blotted to nitrocellulose membranes. The KEL glycoprotein was detected using the mouse mAb, MM0435-12 three (Novus Biologicals, Littleton, CO) followed by goat anti-mouse IgG1 HRP (Bethyl Laboratories, Montgomery, TX). Detection of -actin was applied as a loading manage. Bands were detected with Immobilon Western Chemiluminescent HRP Substrate (Millipore, Darmstadt, Germany).Author Manuscript Author Manuscript Author Manuscript Author ManuscriptJ Immunol.
