Product Spotlight for 2/11/20: "Plant One In Your Lab"

In a recent PepTalk, the Ginkgo biloba was in the spotlight, and now the Product Spotlight visits the plant kingdom too. In the kingdoms of living things, plants are the second largest group, boasting over 250,000 species identified so far, and second only to the animal kingdom. Like animals, plants also have innate immune systems and defenses, with processes that are surprisingly similar in each. Many peptides, like CIF1, CLE25, phytosulfokine, and TDIF (CLE41/44 peptide), are involved in cell-signaling, while others are enzyme substrates. Canaline, a toxic ornithine derivative, is produced by legumes as protection from herbivores.

We are pleased to offer the following products for plant research. We can also custom synthesize a peptide to meet your needs.

  • Fmoc-Can(Trt)
    FLX-2333
    This reagent is used for the synthesis of Canaline-containing peptides. It is a derivative of ornithine, a naturally occurring amino acid with an O-alkyl hydroxylamine side chain that is produced by arginase from Canavanine. Due to its toxicity, by its ability to form oximes with carbonyl-containing biomolecules, it is produced by legumes as protection from herbivores. L- Canaline possesses anti-tumor activity against human acute leukemia T-cells, and as a result is of interest in cancer research. It also possesses antimalarial and antineoplastic properties.
