They make too much M protein, which causes the blood to become thick.

In most patients, the amount of M protein stays the same and there are no symptoms or problems.

Detection of an M protein in the serum or urine.

For this reason, baseline and follow-up measurements of the M protein should be done by the same method.

The M protein, however, can methylate on its own.

Other researchers say it is safest to avoid the M protein fragments altogether.

One such molecule is the M protein produced by certain streptococcal bacteria.

Measure and follow the amount of M protein light chains excreted in the urine over 24 hours.

Identify the heavy and light chain of the M protein by immunofixation electrophoresis.

In some patients, the plasmacytoma may shrink, but not disappear, and the M protein persists.

The abnormal plasma cells produce M protein that may be found during a routine blood or urine test.

M protein is a virulence factor that can be produced by certain species of Streptococcus.

The M protein usually lasts about 60 days after infection, while G persists for life.

About 25% of patients have serum and/or urine M protein; this should disappear following adequate radiation.

In other cases, persistence or an increasing M protein may herald progression to multiple myeloma.

However, it is still not entirely clear whether the L and M proteins are part of the virion.

M protein is strongly anti-phagocytic and is a major virulence factor.

At times, patients with Waldenström macroglobulinemia may exhibit more than one M protein.

Dr. Dale has taken pieces of the M protein from six different types and strung them together.

In addition, the bacteria have proteins on their surface, called M proteins, that thwart the immune system.

It has been shown that M protein also induces apoptosis in the absence of other viral components.

The M protein found on some serotypes is also able to prevent opsonization by binding to fibrinogen.

But strep's M proteins prevent that.

The Faracci tester reported high concentrations of hyaluric acid and M proteins.

These diseases are all associated with a monoclonal (or myeloma) protein (M protein).
