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.

Source: Expression and purification of exendin-4, a GLP-1 receptor agonist, in Escherichia coli.

What the research says

Roughly balanced

Support and challenge are close. The picture may shift as more studies come in.

Supports

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Quantitative

In plain English

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.
