About this material

What it is

A 28-residue acetylated peptide, the longest sequence currently stocked. Longer chains are harder to resolve cleanly, so the certificate for this item records the full gradient and column conditions used — enough detail to reproduce the separation rather than just read the number at the end of it.

Laboratory handling

Storage and material handling

  1. 01Equilibrate the sealed vial to ambient temperature before breaking the seal.
  2. 02Longer sequences are more sensitive to repeated handling. Aliquot on first opening.
  3. 03Log each freeze-thaw cycle against the lot in your own records.
  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.

Gradient conditions were actually on the certificate

The certificate lists the column, the gradient and the detection wavelength. I reproduced their separation on our own instrument and landed within a tenth of a percent of the released figure. A purity number without the method behind it is not a number.
