Most assays are now available for use with a range of different analytical fluids, including serum, plasma or urine.
Most assays suited for measuring CD8 cell frequencies require prior knowledge of immune dominant peptides.
Most assays available for testing proteolytical activity of proteases are performed in vitro, using heterologously expressed proteases and peptide substrates.
Fluorescence detection is the basis of most assays used in drug discovery and High Throughput Screening (HTS) today.
The stirring rate was controlled to always be 200 rpm in most assays, exceptions being during the assessment of external mass transfer limitations.
Despite its importance, most assays for DNA damage are very low throughput, as little has been done to introduce engineering principles.
In addition, when used in an affinity capture-buffer exchange format the final samples are formulated in a buffer compatible with most assays without requirement of additional downstream processing.
Most assays that exist today are based on cell lines often over-expressing the substrate.
Storage at room temperature for 3 days after lyophilization also did not appreciably reduce the activity in most assays.
Most assays use a maximum concentration of 0.0001 M (the cell line screen and GI50 parameter are described in [7]).
The iPS cells behave similarly to ES cells in most assays, including contributing to mouse germline transmission [9].
