Cd3 145 2c11 cd4 gk1.5

Manufactured by Thermo Fisher Scientific

The CD3 (145-2C11) CD4 (GK1.5) is a set of antibodies used for the detection and analysis of mouse T cell subsets. The CD3 antibody binds to the CD3 complex, which is expressed on all mature T cells. The CD4 antibody binds to the CD4 co-receptor, which is expressed on a subset of T cells. These antibodies are commonly used in flow cytometry applications to identify and characterize T cell populations.

Single cell suspensions were prepared as previously described 15 (link), and contaminating erythrocytes were lysed using ammonium chloride buffer where appropriate. Cell suspensions were stained with optimal dilutions of antibodies directly conjugated to either Biotin, FITC, PE, PE-Texas Red, PE-Cy5.5, PerCP-Cy5.5, PerCP-eFluor710, PE-Cy7, Pacific Blue, eFluor 450, allophycocyanin, Alexa Fluor 647, or allophycocyanin-eFluor 780. Biotinylated antibodies were visualized using streptavidin PE-Texas Red (BD Bioscience). Lineage positive cells were gated out of whole BM suspensions using mouse hematopoietic lineage eFluor450 cocktail (eBioscience).The following specific antibodies were used to detect cell surface antigens: CD117/c-Kit (2B8), Sca-1/Ly6A/E (D7), CD127/IL-7Rα (A7R34), CD34 (RAM34), CD135/Flt3 (A2F10), CD25 (PC61.5), AA4.1 (AA4.1), CD27 (LG.7F9), CD150 (mShad150), CD48 (HM48-1), CD244.2 (eBio244F4), CD45.1 (A20), CD45.2 (104), GR-1/Ly-6G (RB6-8C5), CD11b (M1/70), CD11c (N418), CD45R/B220 (RA3-6B2), CD19 (eBio1D3), CD3 (145-2C11), CD4 (GK1.5), and CD8 (53-6.7). All antibodies were obtained from eBioscience. The CD1d PBS-57 tetramer was obtained from the NIH Tetramer Core Facility (Emory University, Atlanta, USA).

Hepatic non-parenchymal cells (NPC) and spleen cells were treated with FcγR-blocking rat anti-mouse CD16/32 mAb (2.4G2) to prevent non-specific antibody (Ab) binding. They were then incubated for 30 min with fluorescein isothiocyanate (FITC)-, phycoerythrin (PE)-, APC-, PE-cyanin (Cy)5-, PE-Cy7-or pacific blue-conjugated monoclonal Abs (mAbs) to detect surface expression of CD3 (145-2C11) CD4 (GK1.5) or CD8 (53–6.7) (all eBioscience, San Diego, CA). For intracellular cytokine staining, cells were fixed with 4% paraformaldehyde and permeabilized using 0.1% saponin, then stained with anti-mouse IFN-γ Ab (XMG1.2) (BioLegend). For forkhead box p3 (Foxp3) staining, cells were fixed and permeabilized using Foxp3 Fix Perm kit (eBioscience) and stained with anti-Foxp3 mAb (FJK-16s) (eBioscience). Appropriate Ig isotype controls were obtained from BD Pharmingen (San Diego, CA). Flow analysis was performed using an LSR Fortessa flow cytometer (BD Biosciences) and results expressed as percent positive cells and mean fluorescence intensity (MFI).

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.
