How to dilute a protein (.05 mg) and make its concentration into 2000 U/ml. The protein is INF gamma which has been provided .05 mg in lyophilized form. It can be reconstituted in PBS but we require 2000 U/ ml in our media.
I am on the lookout for the Enhanced Yellow Fluorescent Protein (Aequorea victoria) DNA sequence. Does anyone know where I can find it? Thank you in advance
