We are planning to do ELISA/ spectroscopy-based study. How to make it for time and dose-dependent assay, like OD values should be taken for every 20secs for 20 mins? Hence, how to calculate Vmax value?
Please suggest some standard drug and its IC50 concentration which is applicable for CHO cell line.
