Peptide Modification
- Why it is difficult to synthesize peptide with FITC without the Ahx linker?
- Do you provide peptoid service?
- Can you cyclize my peptide by disulphide bond (cysteine bridge) while my peptide sequence contains 3 cysteines?
- Can you make branched peptides? If yes, how long would each branch be? Can you make two branches on one original peptide? If yes, how far should two branches separate from each other?
- As for the biotinylated peptide I would like to order we have to be sure that there are absolutely no toxic byproducts in those peptides. Please describe how you remove potentially toxic ingredients such as guanidine salts, DMSO etc.
- What is the size of your mini-PEG?
- Where can I find the full name of a certain peptide modification?
- Can Genscript perform KLH or BSA conjugation on peptide with no cys in sequence?
- Can you label my peptide with FITC directly at N-terminus?
- What are the advantages of PEGylation of peptides?
- Does Genscript sell fluorescent labeled synthetic peptides with quencher?
- We would like know are you able to do isotopic N and C labeled peptides?
- Can a biotin residue be added at the C-terminus of a peptide? Can a spacer be added at C-terminus to increase the space between the peptide and the C-terminus biotin?
- Can you make the peptide with aspartic phosphorylation modification?
- Could you let me know fluorescent tags you have available for N-Terminus peptide modification?
- How many disulfide bonds can you make in peptide synthesis?
- What is the advantage of capping the N and C terminal of the peptide?
- Are there any requirements for phosphopeptide design?
