Immunofluorescent protein detection in Western blotting

This report describes the detailed procedures for Western blot analysis using fluorescent antibodies. After electrophoresis and subsequent electroblotting, the fluorescent-labeled antibodies were visible upon ultraviolet illumination of the polyvinylidene fluoride (PVDF) membranes and could then be photographed to give an accurate record of the blots. Fluorescent labeling allows for photographi...

Steroid hormone receptors in human salivary gland tumours.

Major salivary gland tumours were studied for the presence of hormone receptors for oestrogen and progesterone. Of the eight salivary gland tumours exhibiting varied histology, none showed high affinity receptors for oestrogen or progesterone. Salivary tissue from four patients with non-neoplastic salivary gland disease was also studied and found not to contain high affinity receptor sites. The...

Fluorescein angiography of anterior uveal melanocytic tumours.

A retrospective analysis of 32 cases of anterior uveal melanocytic tumours included 14 cases in which the tumours could be categorised histologically as malignant, of intermediate cytology with equivocal features of malignancy, or as benign progressive naevi. An additional eight cases without a histological diagnosis were included as benign naevi, because there had been no change in their clini...

Immunohistochemical detection of dopamine D2 receptors in neuroendocrine tumours.

BACKGROUND Recently, dopamine D2 receptors (RD2) have been found to be expressed in neuroendocrine tumours (NET), the tumours which arise from the diffuse neuroendocrine cells. Moreover, successful trials of the treatment of NET with cabergoline - D2 agonist, have been reported. These findings increase the interest of investigating RD2 expression in NET. MATERIAL AND METHODS The expression of...
