Targeted Modulation of Complement Activation in Lupus Nephritis Using a Bispecific CATCH- Construct

This folder contains a dataset for the SNF funded project "Targeted Modulation of Complement Activation in Lupus Nephritis Using a Bispecific CATCH- Construct" It contains a set of 4 experiments showing binding properties of 1F5 to C1q and binding of 5C6 to Factor H.
