QS-21 fraction is a highly purified, research-grade and GMP-grade saponin fraction isolated from Quillaja saponaria extract using Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC). It is recognized as the 21st significant fraction from the plant extract and is valued for its strong immunostimulatory activity in advanced research applications. This fraction is especially notable for its ability to activate both humoral and cell-mediated immune responses. It supports robust antibody production while also promoting strong Th1 and CD8+ T cell activity, making it a sought-after material in immunology and vaccine-adjuvant research. QS-21 fraction is also known for its synergistic performance when used with the QS-7 fraction, which further enhances its relevance in studies focused on immune response modulation. Because of its high purity and defined fractionation process, QS-21 fraction is suitable for laboratories, research institutions, and biotech developers requiring a consistent and reliable Quillaja-derived saponin fraction for experimental use. Its export-ready and B2B-oriented availability from Swasti Exports makes it an appropriate choice for bulk or project-based procurement in life sciences and pharmaceutical research workflows.
