The Claim
Recombinant exendin-4 can be successfully released from its fusion protein in Escherichia coli using enterokinase cleavage, followed by purification, resulting in a yield of 3.15 mg of the final product per 10 grams of bacterial biomass.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Scientists can make a useful protein called exendin-4 in bacteria, cut it out cleanly using a special enzyme, and end up with a specific amount of the pure protein from a given amount of bacteria.

Recombinant exendin-4 can be released from its fusion protein in Escherichia coli by enterokinase cleavage followed by additional purification, yielding a final product at 3.15 mg per 10 grams of bacterial biomass.
What the research says
1 studyStudy: Expression and purification of exendin-4, a GLP-1 receptor agonist, in Escherichia coli.
The study did exactly what the claim says: it made exendin-4 in bacteria, cut it out using a specific enzyme, purified it, and got the exact amount claimed.
