A monoclonal antibody (7B10) which displays differential reactivity with breast carcinomas compared to benign lesions or normal breast tissue was selected by fusion of spleen cells from BALB/c mice immunized with the T47D human mammary carcinoma cell line. The antigen, rec ognized by 7B10 on T47D cells, appeared to be both surface and cyto plasm localized, as demonstrated by indirect immunofluo...

A monoclonal antibody to Tamm-Horsfall glycoprotein was used for the immuno-localization of Tamm-Horsfall protein in formalin fixed, paraffin embedded tissue sections of childhood renal tumours, normal children's kidneys, and human fetal kidneys. The procedure was a dinitrophenyl hapten sandwich staining method. The antibody, diluted 1/100,000, gave a very strong and specific staining of the lo...

The addition of cholinergic agents and cyclic 3'5'-guanosine monophosphate (cGMP) to polymorphonuclear leukocytes in vitro from a patient with Chediak-Higashi syndrome corrected the impaired release of the lysosomal enzyme, beta-glucuronidase, to normal. Coinciding with the improvement in degranulation, the bactericidal capacity was enhanced to normal. Similar concentrations of cholinergic agen...
