Which substance causes abnormal electrophoretic reactions such as precipitation at low temperatures?

Cryoglobulins are immunoglobulins that precipitate from serum when it is cooled below normal body temperature. In electrophoresis, cooling can cause these cryoglobulins to come out of solution and form a precipitate or gel in the sample, distorting the band pattern and sometimes leaving a visible pellet. When warmed, they dissolve again, so the abnormal pattern is specifically linked to cold conditions. This is why cryoglobulins produce precipitation at low temperatures in electrophoretic analyses. In contrast, fibrinogen, lipoproteins, and haptoglobins do not exhibit this temperature-dependent precipitation behavior in standard electrophoresis.
