How can I limit signal saturation when using the EnzChek Lysozyme Assay Kit (Cat. No. E22013)?
To limit signal saturation when using the EnzChek Lysozyme Assay Kit (Cat. No. E22013), try lowering the voltage (gain) on the PMT (photomultiplier tube). If you are still seeing signal saturation after lowering the voltage, try a shorter reaction time, and/or lower substrate concentration.
May other buffers be used for the EnzChek Lysozyme assay?
Yes. You may use other buffers that are compatible with the enzyme of interest. The buffer provided is optimal for use with chicken egg white lysozyme. If the buffer has a pH <6, adjust the pH to 7.5 to 8 prior to detection for optimal signal from the fluorescein. The emission of fluorescein drops off at pH <6.
