Press Releases

Profacgen, a state-of-the-art protein service provider that provides custom protein services in the biological sciences, enabling access to the latest tools, techniques, and expertise with competitive pricing and rapid turnaround time, now provides an ultimate solution of animal-free protein production services to meet different research needs.

Plant expression systems were used when recombinant protein products without animals were required. Compared with traditional microbial or animal cell systems, animal-free plant expression systems greatly reduce the risk of contamination by pathogens of animal origin. In addition, plant production has superior advantages in storage, distribution and scale-up.

Many plant species have been developed as protein expression systems, for example, rice, tobacco, and Arabidopsis. To obtain transgenic plants for stable protein expression, plant viruses and bacteria are used to deliver the desired genes into the plant host. The most commonly used delivery systems include tobacco mosaic virus (TMV) and Agrobacterium.

Backed by years of experience, Profacgen now provides various animal-free expression services including:

Lettuce Transient Expression System

Among all plant species, the lettuce transient expression system is considered as the most promising system for the expression of recombinant proteins.

Nicotiana Tabacum Expression System

Profacgen has developed a novel Nicotiana tabacum specific expression platform for recombinant protein production at high purity. Recombinant protein expressed from plants generally possesses post-translational modifications, which are required for enhancing protein stability, bioactivity and favorable pharmacokinetics.

Microalgae Expression System

Profacgen provides recombinant protein generation in Chlamydomonas reinhardtii system from gene cloning to protein expression and purification.

Features

High yield (from 2g/kg to 10g/kg of rice seed) High scale-up capability Easy storage and distribution (rice seed containing target protein or peptide can be stored for many years without compromising the bio-activity) Validated highly consistent performance Free of infectious or toxic contaminants Cost-effective Environment friendly
