T cells are activated and induced to proliferate following binding of their respective antigen. The process of includes expression of genes that
encode factors (i.e., cytokines) which regulate various cell types. Modulation of gene expression is conducted by an array of specific
interactions between transcription factors and DNA. NFAT-1 (Nuclear Factor of Activated T cells) is a transcription factor that regulates
expression of the interleukin-2 gene. Thus, NFAT-1 DNA binding activity is undetectable in resting cells, but increases during T-cell
activation. NFAT-1, a protein of 921 amino acids, is part of an oligomeric transcription factor that also contains Fra-1 and JunB. NFAT-1 was
initially described as a phosphoprotein and is dephosphorylated in activated T cells transformed with the leukemia virus HTLV-l.

注意事项:
1.Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2.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.
