gp91 ds-tat peptide (5 μM, 1 h pretreatment before Hcy treatment) restores Hcy-inhibited TRPML1 channel activity in mouse podocytes, reduces Hcy-enhanced exosome release from mouse podocytes and reverses the impaired lysosome-MVB interaction induced by Homocysteine in mouse podocytes[3].

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.
