* Allow all reagents to warm to room temperature for at least 30 minutes before opening.
* Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.
* Unused wells must be kept desiccated at 4 degree C in the sealed bag provided.
* Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.
* It is recommended that all samples and standards be assayed in duplicate or triplicate.

Background: STAT4 is phosphorylated in response to interleukin-12 and is essential for IL12 signal transduction. For further information on STATs. STAT4 and STAT1, which both map to chromosome 2q32, may have arisen via a tandem gene duplication. However, STAT1 was expressed ubiquitously, whereas STAT4 was expressed in specific tissues, including spleen, heart, brain, peripheral blood cells, and testis. STAT4 expression was drastically increased in T cells following treatment with a DNA methyltransferase inhibitor. Truncation of methylation sites in the proximal regulatory elements of the STAT4 promoter markedly enhanced transcriptional activity. The N-terminal protein interaction domain (N domain) of STAT4 is required for STAT4 activation after IL12 signaling.
NCBI and Uniprot Product Information
NCBI Description
The protein encoded by this gene is a member of the STAT family of transcription factors. In response to cytokines and growth factors, STAT family members are phosphorylated by the receptor associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. This protein is essential for mediating responses to IL12 in lymphocytes, and regulating the differentiation of T helper cells. Mutations in this gene may be associated with systemic lupus erythematosus and rheumatoid arthritis. Alternate splicing results in multiple transcript variants that encode the same protein.

Product Notes
The Human STAT4 stat4 (Catalog #AAA9714044) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA9714044 ELISA Kit recognizes Human STAT4. It is sometimes possible for the material contained within the vial of "Signal Transducer And Activator Of Transcription 4 (STAT4), ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
