Purpurin has been obtained from Aldrich’s collection of rare chemicals and rubiadin has been synthesized according to procedures of Takano et al.33 (link). Double distilled water was produced in a distillation apparatus bought from Gebr. Rettberg GmbH. An extended tabby weave with blue warps (wool fibers previously vat dyed using natural indigo) and red wefts (wool fibers previously mordant dyed using alum and cochineal) was handcrafted by a textile archaeologist. Recent animal- and plant-derived fibers dyed with synthetic indigo or E120, a food dye extract from scale insects (Dactylopius coccus Costa), were used for first tests (dyeing processes were performed as previously reported28 (link),34 (link)).
Methanol and acetonitrile
Manufactured by Avantor
Sourced in France, United Kingdom, United States
Methanol and acetonitrile are solvents commonly used in laboratory settings. Methanol is a colorless, volatile, and flammable liquid, while acetonitrile is a colorless, volatile, and polar liquid. Both are widely used as solvents in various analytical techniques, including chromatography and spectroscopy.

E. coli strains included the clinical strain Ec3536 collected from a urine sample of the community patient and provided from the MFP Laboratory collection10 (link). Its conjugative plasmid containing the blaCTX-M-15 gene was transferred by conjugation experiment in a laboratory recipient cell of E. coli K12. Consequently, the transconjugant E. coli TcK12 was resistant to CFX10 (link). Mueller-Hinton bacteria culture medium adjusted in calcium and magnesium ions (MH-CA) and microbiology consumable were purchased from Bio-Rad, France.
Ceftriaxone heptahemihydrate di-sodium salt was pourchased from Discovery Fine Chemical (UK), pharmaceutical grade, batch number: 74786.
Methanol and Acetonitrile (HPLC grade) was purchased from VWR (France).
Demineralized water was prepared at the laboratory by ion exchange (Pure Lab Option ELGA) followed by distillation (Water Still Distinction D4000).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
