What are the typical salts associated with my peptide?
If no acetate exchange was performed then the dominant ion will be trifluoroacetate, one for each basic amino acid and the N-terminus. If you prefer an alternative salt, we can offer an acetate exchange using acetic acid, as an example.
- If I have biotin in my peptide, do I need a spacer between the biotin group and the peptide sequence and if so which spacer should I use?
- What can I do to increase the cell permeability of a peptide?
- How do I solubilize my peptides?
- How do I characterize batches of my "drug candidate" peptide, which contains a D-amino acid?
- How do you calculate hydrophobicity?
