An enzyme-linked immunosorbent assay (ELISA) for direct detection of enteric adenovirus 41 (Ad41) in stool specimens was developed and compared with an Ad40-specific ELISA described previously [Johansson et al, 1980]. Rabbit antiserum to Ad41 was obtained by immunization with purified virions. To el

✦ Synopsis
A solid immunoassay for the detection of protein tyrosine kinases has been developed. It is based on the binding of the synthetic polypeptide poly(Glu.Na,Tyr) 4:1 to microELISA wells, where the phosphorylation reaction takes place in the presence of ATP and enzyme. The phosphorylated tyrosine residues produced in the reaction are finally detected, in the same well, by means of an ELISA using monoclonal antiphosphotyrosine antibody, peroxidase-labeled goat anti-mouse IgG antibody, and substrate. The amount of protein tyrosine kinase activity present in the sample is proportional to the color at 492 nm developed in each well.
