Final answer:
Yes, lysis buffer can be used to directly extract proteins and protect tissue morphology.
Step-by-step explanation:
Yes, lysis buffer can be used directly for protein extraction to protect tissue morphology. Lysis buffer is mainly composed of a detergent solution that breaks open cells by destroying lipid molecules in cell and nuclear membranes. It also inactivates macromolecules such as proteins and RNA, which helps preserve the tissue morphology. The DNA or protein can then be extracted from the lysed cells and further analyzed.
