It is common to remove the tissue from the animal and freeze it in isopentane (2-methylbutane, Mallinkrodt). The isopentane is kept in a hood and cooled to −15°C with dry ice. Tissue extraction and blocking do not differ from any standard histological techniques.
Measurement of serum creatine kinase (CK) is a simple diagnostic laboratory test and values are always massively increased from birth (10–100 times normal levels, which, in young healthy adult men, are less than 200 IU); this should be the first test when DMD is suspected.
