Description

S Tag Peptide is a 15 amino acid peptide derived from RNase A.

In Vitro

S Tag sequence is a novel fusion peptide tag for recombinant proteins that allows detection by a rapid, sensitive homogeneous assay or by colorimetric detection in Western blots. S Tag can be applied to purification of target proteins[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.
