3 mg/mL β-chitin nanofibers from squid pens with 2.5 mg/mL perdeuterated N-acetylglucosamine binding Protein A (D-GbpA) in 47 % D₂O - USANS

Data type: SASBDB experimental data Status: Published Curve type: Single concentration Last updated: 2026-02-23T16:31:11.723516+01:00

Guinier analysis and subsequent Rg, I(0) and MW parameters are not applicable for this entry as the Guinier-region occurs at a much lower s-range than the data includes. The chitin fibers are micrometers long.

experiment_descriptionUltra small angle neutron scattering (USANS) data from of β-chitin nanofibers from squid pens mixed with perdeuterated N-acetylglucosamine binding Protein A (D-GbpA) in 20 mM acetate, 47% v/v D₂O, pH 5 were collected on the BT5 USANS instrument at the National Institute of Standards and Technology (NIST; Gaithersburg, MD, United States). Data recorded as I(s) vs s (where s = 4πsinθ/λ, and 2θ is the scattering angle), were collected at a sample concentration of 3 mg/mL chitin and 2.5 mg/mL D-GbpA at 25 degrees centigrade using the following instrument configuration: Sample-Detector distance, 30 m; Wavelength, 0.24 nm; Frames, 1; Time per frame, 11 hours; s-range, 0.0005 nm-1 to 0.01 nm-1.
