Claude helps Anthropic map the first vault particle from prokaryotes
Anthropic says that Claude helped its lab solve the first 3D structure of a vault particle from prokaryotes and cut a three-day purification to about 90 minutes.

Anthropic’s lab reports that a three-day purification took about 90 minutes and that a first model came in 34 hours instead of weeks.

One new structure, of a vault particle from prokaryotes, adds a clue to the open question of what vaults do.
Vaults are large, hollow barrels of protein found in cells across the tree of life. Their function is still unknown. Anthropic’s biology research lab used Claude at each step of a study of vaults in bacteria and in the viruses that infect them. Under the team’s direction, Claude searched protein databases, designed the DNA constructs, optimized the isolation method and processed the microscopy data. The team mapped the first 3D structure of a vault particle found in prokaryotic cells. The particle came from a virus that infects bacteria. Anthropic says that a vault purification that conventionally takes three days took about 90 minutes. A first structural model was ready 34 hours later, which the team estimates would normally have taken weeks. Claude also made errors. A protocol that it wrote called for a growth medium with an additive that keeps DNA out of cells, which set the project back by two weeks. Early in the cryo-EM processing it skipped a standard step and produced a flawed map blended with its mirror image. Anthropic announced the work on 4 November 2026 and submitted a preprint to bioRxiv. The Neuron reported it on 5 November. The time savings are Anthropic’s own estimates.
Not isolated. Anthropic describes Claude’s part at each step, under the team’s direction. The faster purification came from a size-exclusion method that the team chose after Claude first argued against it, and Claude then helped make it work. The time savings are the makers’ estimates, and no outside group has checked them.
Limits
The time savings are Anthropic’s own estimates against a conventional method. The preprint had been submitted to bioRxiv but had not yet appeared, so no outside group had checked the work.
Trade-offs
A protocol that Claude wrote set the project back by two weeks, and Claude produced a flawed cryo-EM map before the team stepped in.
As a result, a vault purification that conventionally takes three days took us about 90 minutes, and a first structural model was ready 34 hours later, which we estimate would normally have taken us weeks.
the first 3D structure of a vault particle found in prokaryotic cells
A protocol it wrote called for a growth medium containing an additive that interferes with getting DNA into cells, which set the project back by two weeks.
In a November 4 announcement, Anthropic revealed that its biology team used Claude to reconstruct the first 3D structure of a vault particle derived from a virus that infects bacteria.
But the AI also made mistakes, including one that delayed the experiment by two weeks.

Workflow
A language model given database searches, DNA design, method optimization and cryo-EM processing under a research team’s direction. A wet lab that produced the proteins in bacteria and imaged them by cryo-electron microscopy.
Follow-up
Conditions for replication
Researchers must check each step, as the protocol error and the flawed map show. The lab needs large protein databases and the computing to process cryo-EM data.
