8-Mercaptoguanosine  (Synonyms: 8-Thioguanosine)

Cat. No.: HY-111782
Handling Instructions

Molarity Calculator

8-Mercaptoguanosine is an immunoadjuvant that affects the in vivo antibody response to the T-cell-independent antigen TNP-Ficoll. 8-Mercaptoguanosine enhances IgG1, IgG2, and IgG3 antibody responses, but has no effect on IgM antibody responses. 8-Mercaptoguanosine also enhances antibody responses to very weak antigens such as pneumococcal polysaccharide and restores antibody responses in immunodeficient xid mice that are non-reactive to TNP-Ficoll.

For research use only. We do not sell to patients.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
