An ELISA method for the detection of salivary amylase in dried stains using a monoclonal anti-human salivary amylase antibody was developed. Studies demonstrated the assay to be sensitive down to 0.0002 Sigma units and showed a linear response between absorbance and salivary amylase activity between 0.002 and 0.2 units. The assay showed no cross reactivity(More)
Homology between the two repeat (R) regions in the retroviral genome mediates minus-strand DNA transfer during reverse transcription. We sought to define the effects of R homology lengths on minus-strand DNA transfer. We generated five murine leukemia virus (MLV)-based vectors that contained identical sequences but different lengths of the 3' R (3, 6, 12,(More)
