Description

Description: This TU27 monoclonal antibody reacts with human CD122, which is also known as interleukin-2 receptor beta (IL-2R beta). This receptor is expressed on NK cells, activated T cells, some B cells, monocytes, and T cell leukemias. CD122 can also be detected during early NK cell commitment. IL-2R beta associates with the IL-2R alpha (CD25) or IL-15R alpha and common gamma chain (CD132) to form the high affinity IL-2 and IL-15 receptors, respectively. By itself, this membrane receptor can bind IL-2, but with intermediate affinity. The binding of IL-2 results in internalization of the cytokine, tyrosine phosphorylation of IL-2Rbeta, and activation of signaling cascades such as the JAK/STAT pathway. Applications Reported: This TU27 antibody has been reported for use in flow cytometric analysis. Applications Tested: This TU27 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0.25 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. PerCP-eFluor® 710 emits at 710 nm and is excited with the blue laser (488 nm); it can be used in place of PerCP-Cyanine5.5. We recommend using a 710/50 bandpass filter, however, the 695/40 bandpass filter is an acceptable alternative. Please make sure that your instrument is capable of detecting this fluorochrome. Light sensitivity: This tandem dye is sensitive to photo-induced oxidation. Please protect this vial and stained samples from light. Fixation: Samples can be stored in IC Fixation Buffer (Product # 00-8222) (100 µL of cell sample + 100 µL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product # 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically. Excitation: 488 nm; Emission: 710 nm; Laser: Blue Laser. Filtration: 0.2 µm post-manufacturing filtered.

Experimental details

Fig. 3 Transitional memory and effector memory cells were most frequently infected by C-HIV Envs. a Each data point represents the percentage of infected CD4 + T cells with one pseudovirus (averaged from four independent seronegative blood bank donors). The Env donor is indicated as follows; CAP88 (blue circles), CAP177 (red squares), CAP228 (green triangles), CAP255 (purple inverted triangles) and CAP257 (orange diamonds). Black lines represents the median of all pseudoviruses within each time point. Comparisons were made using a Kruskal-Wallis test with Dunn's post hoc test for multiple comparisons. b Stacked bar graphs represent the contribution of each T cell subset to the pool of infected CD4 + T cells. Values represent the median percentage of infected CD4 + T-cells (averaged across four HIV-seronegative PBMC donors) that belong to the indicated subset [naive; dark blue, T stem cell memory (TSCM); red, central memory (CM); yellow, transitional memory (TM); light blue, effector memory (EM); purple and terminally differentiated (TD); green], and are stratified by participant and time point. Error bars represent the interquartile range. c Dot plot representing the proportion of each T cell subset contributing to the total pool of infected cells for all Env-pseudoviruses. Each point represents a single virus averaged across four seronegative donors, lines represent median and error bars represent interquartile range. Comparisons were made using a Kruskal-Wallis test with Du
