01Quantitative analysis of proteins

Protein quantitative analysis refers to the qualitative and quantitative analysis of the protein group in the sample using mass spectrometry. Currently, it includes non-targeted relative quantitative analysis and targeted absolute quantitative analysis.

02Qualitative analysis of proteins

​Protein qualitative analysis refers to the identification and sequence analysis of proteins in a sample using mass spectrometry. The most widely used strategy for protein qualitative analysis is "bottom-up", which involves protein digestion by proteases into peptide segments, mass spectrometry analysis of peptide segment information, and the use of software for database retrieval or De Novo a...

Service Guide

2023 Recommended Simplified Mthods more
2023 Research workflow Labelled quantitative analysis ITRAQ/TMTFor protein samples that require labeled quantitation, after extracting high-quality proteins, isotopic labeling is required for the samples. The labeling reagents can be selected based on the number of samples (iTRAQ: 2-8 samples, TMT: 2-10 samples).Label-free quantificationFor label-free quantitation (LFQ) analysis in proteomics, there are two main meth... more
2023 Differential quantification Differential quantitation based on proteomics is similar in purpose to transcriptome chips and RNA-Seq. The goal is to identify differences in protein expression levels between two or more different states, times, or varieties of samples. This information is used to correlate and further study the differences in phenotype. This is currently the most widely used and closely integrated technical ... more
2023 Sample preparation Freshly collected samples are frozen directly in a -80°C freezer.Once the sample is collected, send it with dry ice. Be careful to avoid repeated freeze-thaw of samples throughout the process of cryo-preservation and shipping to prevent protein degradation more
2023 Sample source Samples from a variety of sources can be analyzed with no special requirements as to thesourceof the sample. Such as model animals, tissues, cultured cells, body fluid samples, plants, microorganisms, etc., can be analyzed in proteomics more
