IgG and Abs against cell type–specific markers. Mima-8 recognizes the Jsb epitope around the human KellIL-2 Protein Gene ID Author Manuscript Author Manuscript Author Manuscript Author ManuscriptJ Immunol. Author manuscript; available in PMC 2018 February 01.Gibb et al.Pageglycoprotein, which can be expressed by the K1 transgene. A mixture of Mima-8 and Mima-9, which recognizes Kpb epitopes from the K1 transgene, was utilized to examine K1 expression by KEL1A and K1 mice. Platelet-rich plasma was generated by centrifuging peripheral blood at 8000 g for 10 min. For analysis of dendritic cells (DCs), spleens had been minced having a razor blade and filtered through 100 m Nylon mesh before RBC lysis. Single-cell suspensions have been stained with fluorescently conjugated Abs certain for cellsurface proteins, which includes CD19 (Clone: 6D5), TCR (H57-597), and I-A/I-E [MHC class II (MHCII), M5/114.15.2], CD86 (GL-1), Ly6C (HK1.four) 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 employed to exclude dead cells. Cells have been acquired having a Miltenyi MACSQuant flow cytometer and analyzed applying FlowJo. Generation of bone marrow chimeras Recipient WT C57BL/6 (CD45.2+) and Ifnar1-/- (CD45.2+) mice were exposed twice to xray irradiation (six.35 Gy, 3 h apart) making use of an X-RAD 320 irradiator (Precision X-ray, North Branford, CT). Recipients had been injected i.v. with three 106 bone marrow cells from WT C57BL/6-Ly5.1 (CD45.1+) or Ifnar1-/- mice 2 h immediately after irradiation. Peripheral blood was analyzed for lymphocyte reconstitution 6 wk immediately after bone marrow transfer. CD45.1 and CD45.two congenic markers have been made use of to identify 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 have been enriched for DCs making use of a mouse pan-DC enrichment kit (19763; Stemcell Technologies, Vancouver, BC). Enrichment was examined by flow cytometry. mRNA was isolated with 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 Rapidly qPCR kit (KAPA Biosystems, IL-2 Protein Storage & Stability Wilmington, MA), employing a Stratagene Mx3000P instrument. 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 analysis Peripheral blood cells from K1 and C57BL/6 WT mice were lysed applying hypotonic sodium phosphate. Samples had been decreased, electrophoresed on a polyacrylamide gel, and blotted to nitrocellulose membranes. The KEL glycoprotein was detected making use of the mouse mAb, MM0435-12 3 (Novus Biologicals, Littleton, CO) followed by goat anti-mouse IgG1 HRP (Bethyl Laboratories, Montgomery, TX). Detection of -actin was utilised as a loading control. Bands had been detected with Immobilon Western Chemiluminescent HRP Substrate (Millipore, Darmstadt, Germany).Author Manuscript Author Manuscript Author Manuscript Author ManuscriptJ Immunol.
