Invivogen QS-21 (STIMULON®) VacciGrade™ 1mg, Saponin vaccine adjuvant formulation of STIMULON® QS-21 from cultured plant cells – Sterile
Supplier: Invivogen VACQS211
InvivoGen provides QS-21 VacciGrade™, a sterile and potent vaccine adjuvant obtained from plant cell culture of authenticated native Quillaja saponaria trees [1]. This innovative cultured plant cell production of QS-21 (cpcQS-21) offers a uniform quality and a sustainable alternative to conventional QS-21 extracted from the tree bark (beQS-21). Indeed, the limited cultivation of Chilean soapbark trees Quillaja saponaria, coupled to the intricate and costly bark extraction, makes conventional QS-21 (STIMULON® beQS-21) a scarce and expensive adjuvant.
