GTP also known as Guanosine-5 -triphosphate can be utilized in various molecular biology applications such as in vitro transcription RNA amplification and siRNA synthesis Additionally GTP plays a critical regulatory role in signal transduction as a phosphate or pyrophosphate messenger it activates G-proteins which subsequently initiate protein kinase-mediated signaling cascades thus influencing cellular behaviors including cell proliferation and differentiation GTP also serves as a high-energy nucleotide precursor participating in enzymatic synthesis processes of DNA and RNA This product is prepared from GTP trisodium salt with purity 99% (HPLC) as a clear colorless aqueous solution at a concentration of 100 mM and pH (25 C) of 7 0 0 1 free from DNase and RNase contamination
