While doing the crude protein extraction from Yeast cells, for stress bio-marker assay,
a. does the involvement of sonication step is crucial ?
Thank you
Hi Bhavya, sonication is usually included in purification steps to disrupt organelles and protein aggregates that cannot be solubilized easily by detergents alone.
Dear Stefansson,
thank you for your valuable answer.
Yes, otherwise, you will lose a big amount of proteins specially insoluble ones. Good luck
The literature and data sheets mention the water as the best solvent to dissolve reduced GSH, they also mention the oxidization of GSH in an aqueous medium. But few protocols suggest using Buffer...
