VSA 2
Semisynthetic Saponin Adjuvant-VSA 2
*Use only for intended field-of-use in human and animal vaccination research.*
VSA-2 is a semisynthetic saponin adjuvant prepared from naturally occurring and readily available Momordica saponin and capable of stimulating antigen-specific humoral and cellular immune responses. It is prepared by incorporating a terminal-functionalized side chain to the branched trisaccharide domain at the C3 position of Momordica saponin II (MS II) isolated from the seeds of perennial Momordica cochinchinensis Spreng. Direct comparison of VSA-2 and the clinically proven saponin adjuvant QS-21 shows that VSA-2 is comparable to QS-21 in enhancing humoral and cellular immune responses.
