Biological Activity

제품 설명

QS-S2 is the impurity of QS-21 (HY-101092A). QS-21 is an innate immune system-targeted adjuvant^[1]^[2].

In Vitro

QS-21 is a mixture of QS-21-Xyl (250643-56-2) and QS-21-Api (141256-04-4), with a ratio of 35:65. QS-21 is promising for research of oncology vaccines (e.g., melanoma) and infectious disease vaccines (e.g., HIV, malaria)^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
