human brucellosis is a major health problem in developing countries. a number of patients with human brucellosis do not recover from the acute stage of the disease and pass into the chronic form. since the pathophysiology of this change is not well understood, we studied the t-cell subsets during the acute, subacute and chronic forms of human brucellosis. in this study we found alterations in t...

introduction: the present study was undertaken to produce alkaline phosphatase anti- alkaline phosphatase (apaap) complex and to use it in one of the most practical methods of determining the site of antigen in tissue or in cell, i.e. apaap technique, and its comparison with similar foreign products. materials and methods: in this basic and applied study the secreted antibodies of the two hybri...

AIMS To develop and immunohistochemical staining method for cryostat and paraffin wax sections so that two different antigens in the same section of tissues could be detected by combining immunoenzyme and immunofluorescence techniques. METHODS This double immunohistochemical staining method combines alkaline phosphatase-anti-alkaline phosphatase (APAAP) using New Fuchsin as a chromogen and in...

Immunophenotyping of acute leukaemias has become an important diagnostic tool in haematology laboratories as it is now well recognised that the presence of certain surface markers has prognostic significance. In 1988, we experimented with the alkaline phosphatase anti-alkaline phosphatase (APAAP) method for immunophenotyping of leukaemic cells in our laboratory. 48 cases of peroxidase-negative ...

introduction: production of monoclonal antibody against alkaline phosphatase for application in immunohistochemical and immunocytochemical techniques such as alkaline phosphatase anti-alkaline phosphatase (apaap) method. material and methods: in this investigation female balb/c mice were immunized by several injections of alkaline phosphatase and the antibody titer in their sera were measured a...

Phenotyping of cytokeratin (CK)18-positive cells in bone marrow is gaining increasing importance for future prognostic screening of carcinoma patients. Urokinase-type plasminogen activator receptor (uPA-R) is one example of a potential aggressive marker for those cells. However, a valid and reliable double staining method is needed. Using monoclonal antibodies against uPA-R and CK18, we modifie...

Aims: To extend the alkaline phosphatase-antialkaline phosphatase (APAAP) immunoenzyme single stain method to a more generally applicable double stain technique. This will allow two primary antibodies of the same isotype ofIgG and specifically the nuclear antigen bromodeoxyuridine (BRdU) to be evaluated with a cell surface antigen identifier. Method: Sequential applications of the APAAP method ...

AIMS To determine the optimal working conditions of the alkaline phosphatase-antialkaline phosphatase (APAAP) method to establish a specific and sensitive assay for the detection of low numbers of MDR positive cells in patients with hematological malignancies. METHODS Three monoclonal antibodies (C-219, JSB-1, MRK-16) were used for the detection of P-glycoprotein (P-gp) in cell lines and in s...
