Anti cd3e v450 500a2

Manufactured by BD

Anti–CD3e-V450 (500A2) is a laboratory product that can be used to detect and analyze CD3e-positive cells. It is a fluorochrome-conjugated antibody that binds to the CD3e antigen on the surface of T cells. The core function of this product is to facilitate the identification and characterization of T cell populations in samples through flow cytometry or other relevant analytical techniques.

Immune Cell Isolation from Murine MLN

Mechanical digestion of the MLN was achieved by a syringe plunger. After mechanical digestion, single cells were obtained by passing the cells through a 70-μm cell strainer (VWR International, Radnor, PA). Red blood cells (RBC) were lysed using RBC lysis buffer (BioLegend, San Diego, CA). Cells from 2 mice in the same experimental groups were combined to increase cell numbers for analyses. For T-cell populations, cells (1 × 106 cells) were stained with antibodies anti–CD3e-V450 (500A2; BD Biosciences, Franklin Lakes, NJ) and anti–CD4-PE-Cy5 (RM4-5; BD Biosciences). For B-cell populations, cells (1 × 106 cells) were labeled with anti–CD19-PE-Cy7 (1D3; BD Biosciences) and anti–MHC-II-FITC (2G9; BD Biosciences). Populations of T and B cells then were determined by a BD LSR flow cytometer (BD Biosciences ). Flow cytometry data were analyzed using FCS Express 6 Flow Cytometry Software (De Novo Software, Glendale, CA). The gating strategy used to determine immune cell populations is presented in Supplemental Figure 1.

Multicolor Flow Cytometry Immunophenotyping

Cell suspensions in PBS + 0.5% BSA were pre-incubated with Mouse Fc Block (BD Biosciences) for 5 min at 4°C (0.5 μg/106 cells/100 μl), then incubated with fluorophore-conjugated anti-mouse monoclonal antibodies for 30 min at 4°C (dilutions determined by titration). The cells were fixed in BD stabilizing fixative (BD Biosciences). Monoclonal antibodies specific for mouse hematopoietic surface lineage markers, or isotype-matched control antibodies, were used with the fluorophores V450 (eFluor450), PE, PE-Cy7, PerCP, FITC, AF647, and APC-eFluor 780 for seven color-labelling of cells. Anti-CD45-PerCP (clone 30-F11), anti-Ly6G-FITC (1A8), anti-Ly6C-PE or –PECy7 (AL-21), anti-CD11b-PECy7 (M1/70), anti-Siglec-F-PE (E50-2440), and anti-CD3e-V450 (500A2) were from BD Biosciences. Anti-CD11b-APCeFluor780 (M1/70), anti-F4/80-APCeFluor780 (BM8), anti-MHCII-APCeFluor780 (M5/114.15.2), anti-CD11c-AF647 or -eFluor450 (N418), anti-CD4-PECy7 or -AF647 (GK1.5) and anti-CD8a-PE (53-6.7) were from eBioscience. Appropriate conjugates of rat IgG2b, rat IgG2a, rat IgM, and Armenian hamster IgG (eBio299Arm) were used as isotype controls (eBioscience). Labeled cells were analyzed at the Flow Cytometry Core Facility, Massachusetts General Hospital, using a BD SORP 7 Laser LSRII and FlowJo software [30 ].

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.
