August 24, 2015, a new service of protein identification in Creative Proteomics has been carried on the stage. With the help of experienced scientists in Creative Proteomics, these high-quality services are now being available in this field.

There are all kinds of methods to identify protein in Creative Proteomics. These new services can offer users a fantastic identification platform. There is a list of services that Creative Proteomics can offer in protein identification service:

Digestion (in-gel or in-solution)
Sample Preparation
Membrane Proteomics
Subcellular Proteomics
Accurate Mass Determination
Shotgun Protein Identification
Peptide Mass Fingerprinting (PMF)
De Novo Protein Sequence Analysis
Purity Analysis of Peptides and Proteins
Sequence Analysis of Peptides or Proteins (N-, C-)
Molecular Weight Determination and Molecular Weight Distribution of Peptides or Proteins
This news will introduce four typical services in Creative Proteomics.

Sequence Analysis of Peptides or Proteins (N-, C-) in Creative Proteomics includes N-terminal sequence analysis and C-terminal sequence analysis. The N-terminal sequence analysis here is provided with both Edman and Mass Spectrometry of therapeutic proteins, monoclonal antibodies and protein vaccines. Mass spectrometry for protein identification is also quite useful in this field.

Sample preparation is the most significant part of the overall chemical analysis, such as, protein identification. Extraction, isolation, concentration, fractionation, sampling and other preparation steps can take up to 80% of the total analysis time. So it is very complicated and important step in the entire analysis process. Sample preparation in Creative Proteomics can meet all demands in this aspect and it is all up to users to determine preparation service.

The third service in Creative Proteomics is the Peptide Mass Fingerprinting (PMF). It can offer Peptide Mass Fingerprinting analysis and ions searching against a database for rapid identification of proteins. The advantage of PMF in Creative Proteomics is that only the masses of the peptides are needed to be known, while time-consuming de nove peptide sequencing is then unnecessary, as long as the protein sequence is present in the database of interest.

De Nove Protein Sequence Analysis in Creative Proteomics is different from another popular peptide identification methods. An obvious advantage of de novo sequencing is that it can be useful for both database and novel peptides. This service can be used in finding partial amino acid sequences for the design of DNA primers, cloning and DNA/mRNA sequencing and other fields.

The four typical services mentioned above are widely used in this field. Of course, other services for protein identification are also used by many experienced scientists. Creative Proteomics can offer all kinds of services, and users will meet all their demands here and then they can get the best services.
