Characterization

What it is, stated plainly.

What it is

A retro-inverso peptide: built from D-amino acids in reversed sequence, a construction that presents a similar side-chain arrangement to the parent while resisting proteases. It is based on the region of the FOXO4 protein that contacts p53, and is designed to interfere with the FOXO4–p53 interaction. It sits in the cellular-senescence literature.

How a lot is verified

Purity assayed by third-party HPLC and net content (mg per vial) measured by the lab, with a certificate of analysis published where tested. A lot that misses spec is rejected.

Handling & storage

Supplied as a lyophilized powder. Store at −20°C, desiccated and protected from light. Handled per the receiving laboratory's procedures. Not for human consumption.
