About this material

What it is

A palmitoylated five-residue peptide supplied lyophilised in amber glass. Standard reference material for cosmetic-science screening panels. The lipid tail makes the material noticeably more surface-active than unmodified peptides of similar length, which is worth accounting for in recovery calculations — the certificate reports fill mass gravimetrically for exactly this reason.

Laboratory handling

Storage and material handling

  1. 01Equilibrate the sealed vial to ambient temperature before breaking the seal.
  2. 02Lipidated peptides are more surface-active than their unmodified counterparts. Expect adsorption losses on untreated plasticware.
  3. 03Keep in amber glass or foil while on the bench.
  4. 04Dispose of unused material and rinsate according to your institution's chemical waste procedure.

Laboratory storage and material handling only. No dose, concentration, route, frequency or administration guidance is provided for this or any other item, for humans or animals.

Straight answer about recovery losses

Asked about adsorption on untreated plasticware and got a reply describing what the gravimetric fill figure does and does not tell me. They also said plainly that they would not advise on my protocol, which I would rather hear than a guess.
