Antibody type: Monoclonal
Antigen: Other
Description: Description: The MQ1-17H12 antibody reacts with human interleukin-2 (IL-2), a 17 kDa T cell growth factor and a major immunoregulatory cytokine. The MQ1-17H12 antibody is a non-neutralizing antibody. Applications Reported: MQ1-17H12 has been reported for use in staining of intracellular IL-2. Applications Tested: This MQ1-17H12 antibody is tested by intracellular staining and flow cytometric analysis of activated human normal human peripheral blood cells.This product has been pre-titrated and tested intracellular staining and flow cytometric analysis of activated human normal human peripheral blood cells. This can be used at 5 µL (0.125 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Excitation: 633-647 nm; Emission: 660 nm; Laser: Red Laser. Filtration: 0.2 µm post-manufacturing filtered.

Experimental details: Figure 1. NKD2 is involved in regulation of the Ca 2+ -NFAT signaling pathway in T cells (A) Representative immunoblot showing expression of NKD2 in lysates from HeLa cells, unstimulated Jurkat T cells, or those stimulated with PMA + ionomycin or anti-CD3 antibody (Ab) for 6 h. beta-Actin, loading control. Data are representative of two independent experiments. (B) Representative immunoblot showing expression of NKD2 in lysates of control or NKD2 knockout (KO) Jurkat T cells generated using two independent sgRNAs (#1 and #3). beta-Actin, loading control. Data are representative of two independent experiments. (C) Representative traces showing averaged SOCE from control (69 cells), NKD2 KO (KO sgRNA #1, 70 cells) Jurkat T cells, or NKD2 KO Jurkat T cells reconstituted for expression of NKD2 (KO sgRNA #1 + NKD2, 68 cells) after TCR stimulation using anti-CD3 antibodies, followed by ionomycin treatment in the presence of external solution containing 2 mM Ca 2+ . Bar graph (right) shows averaged baseline-subtracted SOCE (+-SEM) from three independent experiments with NKD2 KO cells generated using two independent sgRNAs (#1 and #3). (D) Representative immunoblot of NFATc2 levels in nuclear extracts from wild-type (WT) and NKD2 KO (sgRNA #1) Jurkat T cells stimulated with 1 muM ionomycin for indicated times. A nuclear protein, Ku86, was used as a loading control. Bar graph shows the densitometric analysis of relative band intensities of nuclear NFATc2. Data show means +- SEM of poo

Experimental details: Figure 6. NKD2-mediated ORAI1 + vesicle trafficking is crucial for the effector function of primary T cells (A) Representative histograms showing levels of NKD2 protein in primary T cells transduced with lentiviral vectors encoding scrambled sgRNA (control), NKD2 sgRNA #1, and NKD2 sgRNA #3, together with those encoding Cas9. Cells were permeabilized and stained with anti-NKD2 Ab. The bar graph (right) shows average (+-SEM) from four independent experiments. (B) Representative traces showing averaged SOCE from primary control (73 cells) and NKD2 KO (KO sgRNA #1, 82 cells; KO sgRNA #3, 71 cells) T cells after TCR stimulation using anti-CD3 Abs, followed by ionomycin treatment in the presence of external solution containing 2 mM Ca 2+ . Bar graph (right) shows averaged baseline-subtracted SOCE (+-SEM) from three independent experiments. (C) Representative histograms showing levels of newly inserted PM-resident ORAI1 protein in primary control and NKD2 KO effector T cells after TCR stimulation. Cells were transduced as described above to induce deletion of NKD2 and stimulated and stained as described in Figure 3B for detection of newly inserted PM-resident ORAI1. Bar graph (right) shows average (+-SEM) of pooled technical replicates from three independent donors. (D) Representative flow plots showing expression of IFN-gamma, IL-2, and TNF in control, NKD2 KO (sgRNA #1), and NKD2 KO (sgRNA #3) cells after re-stimulation with anti-CD3 and anti-CD28 Abs. Bar graph shows means +- SE

Experimental details: Figure 1 Decreased frequencies of gammadelta T cells expressing Th1 cytokines in LTB comorbidities. Peripheral blood mononuclear cells (PBMCs) were either untreated or treated with Mtb or positive control antigens for 18 h. The absolute (unstimulated, UNS) and antigen-stimulated (PPD, WCL, P/I) net frequencies of Th1 (IFNgamma, IL-2, TNFalpha) cytokines were shown in LTB DM (n = 20), LTB PDM (n = 20), and LTB NDM (n = 20) groups. Geometric mean values were represented using bars, and every circle denotes a single individual. Kruskal-Wallis test with multiple Dunn's comparison was used to determine the p values.
