Abstract

A comparison between calf thymus extract and rabbit thymus extract to determine their suitability for clinical laboratories in detecting antibodies to extractable nuclear antigens (ENA) was undertaken. Calf thymus extract (CTE) detected 90% more ENA positive patients and 155% more lines than rabbit thymus extract (RTE). In contrast to RTE, CTE resolved Sm and RNP into two distinct lines, had superior stability at -80 degrees C and produced greater clarity of definition of precipitin lines.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
