Special SIL peptide standard library | lyjgbb | 2020-06-10 09:06 | |||||||||||||||||||||||||||||||||||||||||||||||
Hi Skyline Team, I wish Skyline could have a function to allow us to build a special SIL peptide standard library, which includes the customized stable-isotope labeled peptides as standards for our target LC-MS quantification on the unlabeled peptides from either cells or tumor samples. Because we are focusing on the HLA peptides, which are not typical tryptic peptides but they have a kind of diverse peptide sequences, we have a very large SIL peptide library with peptides labeled on diverse amino acids. When we run different samples, we have to choose different SIL peptides from the library, input the corresponding light partners first, and then manually modify the amino acids into SIL version one by one. So this process is very time-consuming and has risks for many human errors. It will be greatly helpful if we can set up a SIL peptide library first in Skyline and then choose the selected SIL peptides per unique sample efficiently from the library, by just inserting the light partners into Skyline. That means Skyline will give users a chance to choose which library (typical protein database or SIL peptide library) they would like to match the peptides with when they insert peptide sequences into the program. Thank you so much for your great efforts and kind consideration! |
