There are two tiers of experiments: (Tier 1) preliminary “Go or No Go” experiments; and (Tier 2) mature projects ready for preparing samples for the X-ray and NMR facility. Tier 1 experiments are the riskiest with no guarantee of success so fees for Tier 1 experiments are based on supply costs only. For Tier 2 fees, these experiments require a lot of time, so staff time is included along with the supply costs. Limited personal use of some of the equipment may be arranged by permission. (fees shown at the bottom) Once the X-ray or NMR data are collected, the processing of these data and subsequent structure solution are not provided by ESBF staff. Collaboration with one of the structural biology faculty is recommended.

TIER 1 Fees1: “Go or No Go” experiments are negotiated and performed in a collaborative fashion and fees are based on supply costs only.
