The Claim
A fusion protein containing exendin-4 can be purified from Escherichia coli lysate using Ni-NTA agarose affinity chromatography, enabling the isolation of the recombinant precursor protein prior to enzymatic processing.
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 fish out a special lab-made protein from bacteria using a kind of molecular magnet, so they can turn it into its final form later.

Fusion protein containing exendin-4 can be purified from Escherichia coli lysate using Ni-NTA agarose affinity chromatography, allowing isolation of the recombinant precursor before enzymatic processing.
What the research says
1 studyStudy: Expression and purification of exendin-4, a GLP-1 receptor agonist, in Escherichia coli.
The study shows that scientists were able to make a protein containing exendin-4 in bacteria and pull it out cleanly using a special filter (Ni-NTA), just like the claim says.
