Custom protein services help to produce these proteins in large quantities, ensuring that they meet strict regulatory standards for clinical and commercial use.
Methods Used in Custom Protein Production
Several techniques are employed to create custom proteins, each of which is selected based on the desired outcome and the specific properties required:
1. Recombinant DNA Technology
Recombinant DNA technology is commonly used to produce custom proteins. This method involves inserting the gene encoding the protein of interest into a host cell, such as E. coli, yeast, or mammalian cells. The host cell then expresses the protein, which is purified from the culture medium. This technique allows for the production of large amounts of proteins with specific modifications.
2. Protein Expression Systems
Protein expression systems include bacterial systems (E. coli), yeast systems, and mammalian systems, each of which is used based on the protein’s complexity and post-translational modifications. For example, yeast and mammalian systems are used when the protein requires glycosylation or other post-translational modifications to be functional.
3. Site-Directed Mutagenesis
Site-directed mutagenesis is a technique used to introduce specific changes to the DNA sequence, which can lead to the production of proteins with altered properties. This is particularly useful in creating proteins with enhanced stability, altered binding affinities, or modified functional properties for use in therapeutic applications.
4. Protein Purification Techniques
Once proteins are expressed, they must be purified to remove any contaminants. Techniques such as affinity chromatography, ion-exchange chromatography, and size-exclusion chromatography are commonly used to isolate the protein of interest. The goal is to achieve a high level of purity to ensure the protein is functional and suitable for its intended application.
5. Protein Characterization
After production and purification, custom proteins are often characterized using methods such as mass spectrometry, Western blotting, and enzyme activity assays to confirm their identity, purity, and functionality. These steps are critical to ensuring the protein meets the specifications for research or therapeutic use.
