生物活性

Kukoamine B, a spermine alkaloid, is a potent dual LPS and CpG DNA inhibitor with Kd values of 1.23 µM and 0.66 µM, respectively. Kukoamine B exerts anti-inflammatory, anti-diabetic, anti-oxidant, anti-osteoporotic and neuroprotective effects. Kukoamine B has the potential for the study of sepsis[1][2][3][4].

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.
