General
- Here is the sequence of the peptide 'QRPRLSHKGPMP', can you make it?
- What is the difference between Net Peptide Weight and Gross Peptide Weight?
- I know that you have technology to ligate small peptides into a long one. Can I send you my peptide fragments and have you ligate them together?
- Do you provide the Material Safety Data Sheet for us?
- What will be the maximum number of consecutive Pro peptide you can make?
- Do you provide reduced peptide?
Peptide Synthesis step
- For the peptide synthesis, can you send me the synthesis protocol that was used including the procedure that was used for making the disulfide bonds?
- Can you provide peptide on resin? What kind of resin you offer?
- What is the ratio of peptide to KLH or BSA when you do conjugation?
- What is the Boc strategy in SPPS?
- What is the Fmoc strategy in SPPS?
- In what direction are the peptides synthesized?
Special Amino Acid
- I also noticed that one of the peptides was pinkish and others yellow.Could you please let me know the reasons?
- How many continuous "R" can we synthesize in a peptide?
- How to convert three letter peptide sequence to one letter peptide sequence, or vice versa?
- Does your company produce peptides with alkyne or azide amino acids?
- Can you synthesize peptides with all D amino acid? If yes, can you provide me a rough idea of turnaround and cost?
- Can you synthesis peptide with Q at N terminal?
Peptide Storage
Peptide Solubility
Peptide QC
- How to read my peptide QC report? Especially the HPLC and MS report?
- I would like to know what quality control measure you employ i.e., how do I determine that the product you sent me is what I wanted?
- What QC (quality control) data we provide from click peptide?
- What quality control data is provided by GenScript?
Peptide Purification
- What is your recommended peptide purity for in vivo application?
- Could you please tell me the % purity that "crude" represents?
- Can you also tell me how do you generally purify your peptides so that I know what kind of impurities I am expecting?
- What methods do you use to purify the peptide?
- What is peptide purity?
- How pure does my peptide need to be?
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?
