In recent years a number of sensitive immunological techniques have been developed to study proteins in biological fluids. The most recently described is that of Minchin Clarke & Freeman (1966) which is a variant of an immunoelectrophoretic method originally described by Ressler (1960) and given the name of crossed immunoelectrophoresis by Laurel1 (1966). It is highly sensitive and by using a c...

A strain of Treponema pallidum isolated from a homosexually acquired penile chancre in Birmingham in 1979 was serially passaged in rabbits and compared with the Nichols strain. The two strains appeared identical morphologically, and no gross differences were detected on antigenic analysis by two-dimensional immunoelectrophoresis. The Birmingham strain was, however, considerably less virulent fo...

In this paper the authors reported 2 cases of Sinus Histiocy-tosis . The first , an 11 year s o1d gir1 with massive 1ymphadnopathy of 10 CM diameter and 3 months duration otherwise normal. Paraclinic exams wer normal including BM. Diagnosis was confirmed by cervical node biopsy. She was followed clinically and was cured in 8 months. The second case, a 6 years old boy with massive cervical lymph...

By means of the antigen-antibody crossed electrophoresis procedure of Laurell, 68 antigens were demonstrated in Candida albicans. This is about four times the number of antigens described earlier by means of classical immunoelectrophoresis. The procedures for obtaining this result are described, including the preparation of antigen, the immunization of rabbits, and the method of N. M. G. Harboe...

Proteins and mucosubstance of the saline extract of human ocular mucus were studied by immunological analysis. A minor study was made with human tears for comparison. Immunoelectrophoresis of proteins from these two sources consistently revealed similar characteristic gel patterns. Proteins were found as the major constituents of both samples. However, more mucosubstance was present in the sali...
