Jurkat cells untreated (negative control, open histogram) or treated with 5 mM of H2O2 for 3 minutes (positive control, solid histogram) were fixed and permeabilized using True Phos Perm Buffer (Cat No. 425401) and intracellularly stained with Alexa Fluor® 647 anti-LAT Phospho (Tyr 171) (clone A20005D), or Alexa Fluor® 647 Mouse IgG2b, κ isotype control (open histogram, dashed line)(representative histogram for untreated and H2O2 treated Jurkat cells) (Cat No. 400330). -
Peripherical blood mononuclear cells (PBMC) untreated (left), or treated with 5mM of H2O2 for 3 minutes (right) were fixed and permeabilizated using True Phos Perm Buffer (Cat No. 425401), and then intracellular stained with Alexa Fluor® 647 anti-LAT Phospho (Tyr 171) (clone A20005D), and Alexa Fluor® 488 anti-CD3 (Cat No. 317310).

LAT, or Linker for Activation of T cells, is a transmembrane protein expressed mainly in T cells and a limited number of other immune cells such as natural killer cells, mast cells, and immature B cells. As an adaptor protein, phosphorylated LAT facilitates the recruitment of other signaling proteins and functions as a nucleating site for multiprotein signaling complexes. These signaling complexes can propagate TCR, or T Cell antigen Receptors, and activate downstream effectors, which trigger T cell proliferation or cytokine expression.
LAT (Tyr171) is one of the nine tyrosines in LAT conserved between human, mice, and rat. LAT (Tyr171) is necessary for the activation of PI 3-kinase, a protein that regulates the recruitment of other proteins that facilitate in T-cell receptor signal transduction such as PLC-gamma1 and Sos1. When LAT (Tyr171) and (Tyr191) is phosphorylated by ZAP-70, Gads can bind directly to LAT (Tyr171) and (Tyr191) and mediate the recruitment of SLP-76.

- Recommended Usage
-
Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µL per million cells in 100 µL staining volume or 5 µL per 100 µL of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.

- Application Notes
-
When this clone is used in WB at a dilution lower than 1:1000 it may show non-specific bands at 50 kD and above.
This clone has been tested by ICC on H2O2 treated and untreated Jurkat, with three fix and permeabilization methods (100% methanol, 4% PFA plus methanol and 4% PFA plus Triton X-100). All three methods can be used for ICC staining, but the PFA plus Triton X-100 fixation/permeabilization method produced the best staining.
This clone has only been tested on True-PhosTM perm buffer (Cat. No. 425401) by ICFC - RRID
