+% TODO add a product number to MTT (if I can find it)
+Cells were stained and visualized using \gls{mtt}. \glspl{dms} with attached and
+loosely attached cells were sampled as desired and filtered through a
+\SI{40}{\um} cell strainer. While still in the cell strainer, \glspl{dms} were
+washed twice with \gls{pbs} and then dried by pulling liquid through the bottom
+of the cell strainer via a micropipette and dabbing with a KimWipe. \glspl{dms}
+were transferred to a 24 well plate with \SI{400}{\ul} media. \SI{40}{\ul}
+\gls{mtt} was added to each well and allowed to incubate for \SI{3}{\hour},
+after which \glspl{dms} with cell were visualized via a brightfield microscope.
+
+To quantify cells on the interior of \glspl{dms}, cells and \glspl{dms} were
+isolated analogously to those for the \gls{mtt} stain up until the drying step.
+Cells were then transferred to a tube containing \SI{400}{\ul} at
+\SI{5}{\mg\per\ml} dispase solution. \glspl{dms} were incubated and rotated for
+\SI{45}{\minute} at \SI{37}{\degreeCelsius}, after which cells were counted as
+already described in \cref{sec:tcellculture}.
