Does anyone have a good protocol for cross-linked chromatin immuno-precipitation from 3-5 weeks mice (including the chromatin preparation part)? I have tried two of them, but find it difficult to purif= y chromatin with a good yield, and at the same time get it clean enough to allow for reproducible immuno-precipitation results. Also, does anyone know what is a reasonable quantity of chromatin to expect from a single brain? Thank you for your help, S=E9bastien Vigneau Other posts:
