METABOLIC LABELING (SILAC)
Stable Isotope Labeling of Amino Acids in Cell Culture. A popular and simple MS technique that using heavy amino acids to metabolically label the proteome of cultured cells in vivo
METABOLIC LABELING (SILAM)
SILAM is a labeling method that employs heavy amino acids or 15N to metabolically label rodent tissues in vivo.
PEPTIDE SYNTHESIS REAGENTS
Synthesised peptides with or without heavy stable isotopes are invaluable for targeted single reaction monitoring (SRM) assays and absolute MS quantitation. CIL offers amino acids and resin for synthesising peptides in your laboratory.
CHEMICAL TAGGING
Chemical tagging refers to labeling proteins or peptides in vitro. This inexpensive method is advantageous over metabolic labeling due to its ability to label human samples and its low cost. In addition, chemical tagging can quantify more than two samples in one MS experiment.
ENZYMATIC LABELING
One of the simplest methods of labeling peptides in vitro is the incorporation of 18O during proteolytic digestion.
PROTEIN EXPRESSION
Expression of large amounts of unlabeled and labeled proteins in heterologous systems is an invaluable tool with numerous biological applications. CIL offers a variety of media for protein expression and kits for in vitro translation.
PEPTIQUANT™ MRM ASSAY KITS
