Protein Quantification Analysis
Isobaric tags for relative and absolute quantification, also known as i-TRAQ, is a protein quantification method using isotopes to “label” proteins from different samples, which results in different molecular weights with the same proteins in different samples.
With this method, you can analyze protein quantification between different samples at the same time.
We also provide label-free analysis to quantify the proteins between different samples, like a serum, for analysis of deeper peptides information.
PROTEIN QUANTIFICATION ANALYSIS – ITRAQ
Isobaric tags for relative and absolute quantification, also known as i-TRAQ, is a protein quantification method using isotopes to “label” proteins from different samples, which results in different molecular weight with the same proteins in different samples.

PROTEIN QUANTIFICATION ANALYSIS – LABEL-FREE
Link Biotech also provides you the label-free analysis to quantify the protein between different samples by using PSM (peptide spectrum match). You could use the label-free analysis to screen the potential biomarker, then for the more accurate result, you could choose the i-TRAQ analysis.
PROTEIN QUANTIFICATION ANALYSIS – LABEL-FREE (SERUM)
There are too many abundant proteins in a serum sample. Even doing the protein depletion step, there’re still have some abundant proteins which will interfere with the detected protein numbers.
To avoid this result, we provide a label-free analysis service to solve your problem.
