EPR spectra were recorded using
a Bruker ELEXSYS E500 CW-EPR spectrometer equipped with an NMR teslameter
(ER 036TM) and a frequency counter (E 41 FC) at X-band frequency,
at 77 K and room temperature. The peptide concentration was 1 mM,
and the metal:ligand molar ratio 1:1.1. The solution for EPR experiments
was prepared using ethylene glycol (5%) as a cryoprotectant. EPR parameters
were obtained by using the Bruker WinEPR SimFonia program and Doublet
new (EPR OF S = ¹/₂) program
by A. Ozarowski (National High Field Magnetic Laboratory, University
of Florida, Gainesville, FL).

Magnetic Susceptibility and High-Field EPR Characterization

Check if the same lab product or an alternative is used in the 5 most similar protocols

Magnetic susceptibility measurements over the temperature range 1.8-300 K were performed at a magnetic field of 0.5 T using a Quantum Design SQUID MPMSXL-5 magnetometer.
Correction for the sample holder, as well as the diamagnetic correction χ D , which was estimated from the Pascal constants, 22 was applied.
High-field, high-frequency EPR spectra at temperatures ranging from ca. 3 K to 290 K were recorded on a home-built spectrometer at the EMR facility of the NHMFL 23 with the microwave frequencies 52-416 GHz. The instrument is a transmission-type device and uses no resonance cavity. The microwaves were generated by a phase-locked Virginia Diodes source, generating frequency of 13 ± 1 GHz, and equipped with a cascade of frequency multipliers to generate higher harmonic frequencies. A superconducting magnet (Oxford Instruments) capable of reaching a field of 17 T was employed. Additionally, X-band and Q-Band spectra were recorded on a Bruker ElexSys E500 instrument equipped with an NMR teslameter ER 036TM and a frequency counter E 41 FC (Faculty of Chemistry, Wroclaw University).

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.
