[ccp4bb] Off-topic question related to ITC binding studies

2022-08-16 Thread ABHISHEK SUMAN
Hello everyone! Hope this email finds you well. I have an off-topic question regarding ITC binding studies, which was asked by a reviewer. We performed an ITC binding study (using Affinity ITC, TA Instruments) to evaluate protein-DNA interaction which resulted in a perfect sigmoidal curve.
