GTW Taurine — 20mL Vial | Glutathione Transport

GTW (Glutathione Transport Water) is a sterile 20mL multi-dose vial research formulation containing 50mg/mL taurine (2-aminoethanesulfonic acid) in a physiologically-compatible isotonic solution, positioned as a companion carrier/transport medium for glutathione research applications. Taurine, a sulfur-containing amino acid derivative, is characterized in academic research literature as a companion sulfur-containing research compound to the glutathione (GSH) tripeptide system — both compounds share sulfur-based redox chemistry and have been extensively investigated alongside each other in antioxidant pathway research and comparative sulfur-containing compound research. The GTW formulation is prepared through quadruple sterile filtration using sterile deionized water as the diluent, buffered to pH 6.8 physiological range, and preserved with 0.9% benzyl alcohol as pharmaceutical-grade multi-dose vial preservative. The quadruple filtration step exceeds standard triple filtration sterile processing, reflecting enhanced sterility protocol appropriate for research applications requiring high-purity companion formulations. Taurine has been investigated across multiple research streams including amino acid pharmacology research, cardiovascular research, mitochondrial research, osmoregulation research, bile acid conjugation research, and comparative research versus other sulfur-containing amino acid derivatives including glutathione. This 20mL vial presentation is offered for laboratory research applications investigating taurine pharmacology, amino acid research, and companion research applications alongside glutathione research studies.
