To help facilitate the synthesis of a broad range of tryptic or peptic peptides, CIL offers a collection of variable, stable isotope-labeled Fmocs. These building blocks are canonical amino acids (e.g., alanine or Ala, isoleucine or Iso, leucine or Leu, lysine or Lys). Please view the availability, pricing, and specifications of our neat Fmoc amino
Natural isotope abundance amino acids, if present in heavy medium, would lead to a mix of light and heavy amino acids in the labeled cell population affectin g the accuracy of quantification. Previous recommendations for branched-chain amino acids (BCAA), based on nitrogen balance studies, were found to be low in a series of stable isotope-labeled amino acid studies. The BCAA requirement was increased in the new dietary reference intake (DRI) report on the basis of a series of stable isotope studies examining the requirement of leucine and valine individually, but not isoleucine. Stable isotope labeling by amino acids in cell culture (SILAC) is a relatively new mass spectrometry-based method in proteomics. In a typical SILAC experiment, a cell culture is grown on a medium with isotope labeled amino acids. During the time the cell culture spends on the medium, proteins will be synthesized from the labeled amino acids. The Free amino acids for structural biology.
