\noindent where $V_{\max}$ is the maximal velocity and $K_m$ the substrate
concentration at half-maximal velocity.

Henderson--Hasselbalch:
\begin{equation*}
	\text{pH} = \text{p}K_a + \log\frac{[\text{A}^-]}{[\text{HA}]}

Beer--Lambert:
\[
	A = \varepsilon \cdot l \cdot c
\]

Hemoglobin Binding Model (cf. \autoref{eq:michaelismenten}):
\begin{align}
    \theta &= \frac{[L]^n}{K_d^n + [L]^n}
             = \frac{1}{1 + \left(\dfrac{K_d}{[L]}\right)^{\!n}}

% Useful when citing several figures at once: \crefcolor{fig:coip,fig:network}
% Do NOT add \usepackage{cleveref} — it is already loaded by the class.
See \crefcolor{fig:pulldown,fig:coip} for the pull-down and co-IP data.

\paragraph{Bibliography citations (superscript coloured [n]).}
As shown previously\cite{Vincent2020}, the complex assembles under stress.
These results are consistent with independent reports\cite{Journo2021,Trizac2019}.

\textit{In vivo}, \textit{in vitro}, \textit{in situ} — always italics.

Multiplication sign: $5 \times 10^{6}$ cells (never letter~x).

  \textbf{Representative confocal micrograph of GFP-tagged Ssa1 in control
  cells.}
  Cells expressing Ssa1-GFP were imaged by confocal microscopy (63× oil,
  0.13\,\um/pixel). Scale bar: \SI{5}{\micro\metre}.
  ($n = 50$ cells from three independent experiments.)%

  \textbf{Western blot confirming equal loading.}
  Total protein extract ($\SI{20}{\micro\gram}$ per lane) was separated by
  SDS-PAGE and probed with anti-PGK1 as a loading control.
  Molecular weight markers (kDa) are indicated on the left.%
