Description

D-Alanyl-L-leucine (D-Ala-Leu) is a dipeptide that acts as a source donor of L-Leucine (HY-N0486)[1].

In Vitro

The pip gene coding for the proline iminopeptidase (Pip) of Xanthomonas campestris pv. citri is cloned in an Escherichia coli leuB strain using a selective medium containing the dipeptide D-Alanyl-L-leucine (D-Ala-Leu) as the sole source of l-leucine[1].

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.
