Ter119 pe cy5

Manufactured by Thermo Fisher Scientific

The Ter119-PE/Cy5 is a laboratory reagent that can be used for the detection and analysis of Ter119-positive cells in flow cytometry applications. It is a fluorescently-labeled antibody that binds to the Ter119 antigen, which is expressed on erythroid cells. The Ter119-PE/Cy5 reagent allows for the identification and enumeration of Ter119-positive cells in a sample.

Myeloid cells were extracted from whole hemispheres, isolated into single-cell suspensions and identified using fluorescence-activated cell sorting (FACS) gating for CD11b+CD45int as previously described (Elmore et al., 2014 (link)). Cells were stained with the following surface antibodies purchased from Biolegend (San Deigo, CA) at 1:200 unless otherwise indicated: CD34-eFlour660 (1:50, 50-0341-80, eBioscience, San Diego, CA), Sca-1-AF700 (1:100, 108141), CD16/32-PE (101307), Ter119-PE/Cy5 (116209), ckit/CD117-PE/Cy7 (25-1171-81, eBioscience), CD150/SLAM-PerCP-eFlour710 (46-1502-82, eBioscience), CD11b-APC (101212), CD11b-PE (101208), Gr1-AF700 (108422), CD45-AF700 (103128), CD45-APC/Cy7 (103116), NK1.1-PE (108707), CD3-PE/Cy7 (100220), CD19-Per-Cyanine5.5 (45-0193-82, eBioscience), CD11c-APC/Cy7 (117323), Ly6C-PE (1:400, 128007), Ly6G-5.5 (127615). For HSCs, CMPs, and GMPs, all cells were gated on live (PI-), Ter119- cells and then identified with the following gating strategy: HSCs: FcyR-, ckit+ Sca+ CD34-, SLAM+, CMPs: FcyR-, ckit+, Sca-, CD35+, and GMPs: FcyR+, ckit+, Sca-, CD34+. Samples were acquired with the BD LSRII or BD Fortessa X20, and sorted with the BD FACS Aria II.

Hematopoietic Stem Cell Transplant Protocol

B6.SJL-Ptprca mice were used at 6–10 wk of age. Mice were irradiated with a split dose of 9GY before transplantation. Each recipient received 1 embryo equivalent of sorted cells via tail vein injection, along with 2 × 104 bone marrow or 2 × 105 splenic helper cells per experiment group from B6.SJL-Ptprca mice unless indicated otherwise. For secondary transplantations, CD45.2+ cells were isolated from recipient bone marrow and 3 × 105 cells were transplanted per recipient with 2 × 105 splenic helper cells. Peripheral blood was collected retroorbitally at the indicated time point after transplantation. Red blood cells were removed with 1% dextran sulfate/0.5% EDTA/PBS (wt/vol) and treated with RBC lysis buffer (Sigma-Aldrich). Leukocytes were then stained in 2% serum/PBS (vol/vol) for CD45.1-FITC (A20; BD), CD45.2-PE-Cy7 (104; BioLegend), Mac1-Alexa Fluor 700 (M1/70; BioLegend), Gr1-PE (A20; BD), CD19-APC-Cy7 (6D5; BioLegend), CD3-APC (145-2C11; eBioscience), Ter119-PE-Cy5 (TER-119; eBioscience), B220-Pacific Blue (RA3-6B2; BD), and propidium iodide (PI). Engraftment was determined to be a percentage of PI and Ter119-negative CD45.2 cells within the CD45-positive population.

Fetal HSCs (Lin-/Sca-1+/c-Kit+/Flk2-/CD150+/CD48-) were isolated from the fetal livers of E14.5 Mcm3+/+, Mcm3+/Lox or Mcm3Lox/Lox CD45.2 C57Bl/6 donor mice, and transplanted into lethally irradiated CD45.1 C57Bl/6 primary recipients (50 fetal HSCs per mouse; 5 mice per group) together with 300,000 Sca-1-depleted CD45.1 helper BM cells. 4 months post-transplantation, the primary recipients were sacrificed to assess the percentage of donor-derived chimerism in the bone marrow (BM), spleen, peripheral blood and HSC compartment and to re-isolate donor-derived adult MCM3+/+ or MCM3Lox/Lox HSCs53 (link). Donor chimerism was analyzed using CD45.2-FITC, (eBioscience 12-0453-83; 1:50), B220-APC-e780 (47-0452-82; 1:800), Gr-1-PB (1:400), Mac-1-PE-Cy7 (1:3200), CD3-e660 (eBioscience, 50-0032-82; 1:400) and Ter-119-PE-Cy5 (eBioscience 15-5921-83; 1:800) antibodies. Re-isolated CD45.2+ donor-derived adult MCM3+/+ or MCM3Lox/Lox HSCs were transplanted into lethally irradiated CD45.1 secondary recipients (500 HSCs per mouse; 5 mice per group) together with 300,000 Sca-1-depleted CD45.1 helper BM cells.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
