CASLO can assist with different types of support, before and after ordering, for example with predicting the solubility, finding the correct fluorochrome to be conjugated, advises about stabilisation, identifying sequences for immunization etc.

Peptides are HPLC purified after peptide synthesis. Peptides can be delivered in nearly all purities from crude or 70% up to higher than 95% or 99%. The correct sequence is controlled by mass spectrometry.

Peptide Modifications

Peptides made by solid phase peptide synthesis can be delivered in nearly all quantities and with a large range of modifications. For example conjugation to carrier proteins, conjugation to fluorochromes, unnatural amino acids, disulfide bonds and a large number of other modifications. Please see the menu “peptide modifications” for more information.

Products are always delivered as lyophilized material. Loaded side chains are counterbalanced by counterions like trifluoroacetate, chloride or acetate according to the order.


Peptides are delivered with detailed certificates including HPLC certificate, mass spectrometry certificate and detailed information and instructions.
