"Preparation of the FAM-WWP2 working solution and MST pre-test."

sparser
"As we describe in the example outlined in Basic Protocol 4, we generate N-terminal fluorescein labeled protein FAM-WWP2 using 5/6-carboxyfluorescein NHS ester."

sparser
"The FAM-WWP2 is purified to be at 2 mg/ml concentration, with around 80% labeling efficiency."

sparser
"We use a working concentration of FAM-WWP2 at 50 nM in the MST binding assay."

sparser
"We prepare 16 serial ligand E2 concentrations by 1:2 dilution and measure the binding affinity to FAM-WWP2 in the MST binding assay."

"Here, we detail a protocol to label WWP2 at the N-terminus using Fluorescein NHS ester (5/6-carboxyfluorescein succinimidyl ester, FAM-NHS ester) adopting a stepwise labeling procedure (Basic Protocol 1 and 2), and then use the labeled FAM-WWP2 to measure its binding affinity to its requisite E2 (UbcH5c) enzyme by performing MST binding assays (Basic Protocol 3)."
