Choosing the Right Recombinant Protein Expression Service
Recombinant protein expression service is a crucial step towards developing biopharmaceuticals. It can be used for various applications including disease treatment, drug discovery and high-throughput screening.
The expression process starts with cloning your gene of interest in an appropriate expression vector. Expression systems differ from one another in terms of the type of proteins they produce, the speed of expression, the ability to withstand harsh conditions and the availability of specific posttranslational modifications. Moreover, they can influence protein solubility and folding as well as protein stability.
Revolutionizing Research with Recombinant Protein Expression Services
As a result, selecting the most suitable expression system for your application is crucial to ensure successful protein production. The article below compares the unique characteristics of four commonly used expression systems — E. coli, Pichia pastoris, baculovirus/insect cells and mammalian cell systems — in relation to key parameters such as protein yield and stability, folding capability and the ability to perform posttranslational modifications.
For example, glycosylated proteins require the addition of sugar moieties to amino acid side chains which can only be performed in eukaryotic systems (such as mammalian cell lines). This feature is particularly important for pharmaceutical applications as it increases protein half-life and reduces immunogenicity in humans. For such proteins, mammalian cell systems are the preferred choice for high-yield production of recombinant protein with good solubility and functionality.
