Preparation And Storage
Product Notices
- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- An isotype control should be used at the same concentration as the antibody of interest.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
- Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
- The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.

STATs (signal transducers and activators of transcription) are critical mediators of the biologic activity of cytokines including Interleukins (IL) 2-5, IL-7, IL-15, GM-CSF, erythropoietin and growth hormone. Ligand-receptor interaction leads to activation of constitutively associated JAK family kinases and subsequent recruitment/activation of STATs by tyrosine phosphorylation. Active STATs then move to the nucleus to promote transcription of cytokine-inducible genes. Seven STAT proteins have been cloned, each of which is differentially expressed and/or activated in a cytokine-specific and cell type-specific manner. Stat6 plays an important role in signaling pathways that lead to the differentiation of T helper type 2 (Th2) cells from uncommitted CD4 T cell precursors. Moreover, IL-4, secreted by activated T lymphocytes, basophils, and mast cells, induces specific gene expression via the induction of tyrosine phosphorylation of Stat6 at tyrosine 641 (Y641). The SH3:SH2 domain of Stat6 associates with tyrosine-phosphorylated IL-4 receptor and the proximal Jak kinase phosphorylates Stat6 at Y641 on the C-terminal side of the SH2 domain. Stat6 is then released from the receptor, dimerizes, and is thought to contact the basal transcription machinery by binding to p300/CBP. While Stat6 is widely expressed in human tissues, it exhibits elevated expression in peripheral blood lymphocytes, colon, intestine, ovary, prostate, thymus, spleen, kidney, liver, lung, and placenta.
The 23/Stat6 monoclonal antibody recognizes Stat6, regardless of phosphorylation status.
