Sample: Fresh Serum (See instructions)

Remarks: MuSK (Muscle-Specific Kinase) is a muscle receptor of Protein Tyrosine Kinase that regulates the formation of the neuromuscular junction.

The anti MuSK  antibodies are detected in myasthemia gravis patients that are negative for anti AChR  antibodies
