Why can't protein production be easier?


Recombinant production of proteins is one of the most powerful technologies in life science. It seems simple in principle -- cloning a gene of interest in the expression vector and transforming it into a host cell.

Yet, it was never easy in practice. Protein production can be frustrating and painfully difficult. A variety of factors may contribute to its failure:

- Overly expression of proteins affects cell growth, which in fact decreases the total yield.
- Proteins are aggregation-prone and so-well expressed, resulting in inactive inclusion body.
- mRNA secondary structures hinder the successful translation.
- And protein production may be failed in a mysterious way....

Every protein has its own manner and temper, and there was no single solution for protein expression. Even if the protein can be easily produced, green fluorescent protein (GFP) for instance, it still requires a sophisticated strategy to optimize the yield. This trial-and-error process among the combination of many variables is extremely tedious.

Free yourself from these repetitive labors, and let us do the dirty work for you! With Ailurus, you can finally spend your precious time and intelligence on science itself.

Ailurus vec ®️, all you need for expression vectors

With Ailurus vec ™ (A. vec for short) platform, you can easily identify an optimal vector to produce your protein with high yield, just by submitting the sequence of interests.
