  We computationally study the effects of binding kinetics to the channel wall,
leading to transient immobility, on the diffusive transport of particles within
narrow channels, that exhibit single-file diffusion (SFD). We find that slow
binding kinetics leads to an anomalously slow diffusive transport. Remarkably,
the scaled diffusivity $\hat{D}$ characterizing transport exhibits scaling
collapse with respect to the occupation fraction $p$ of sites along the
channel. We present a simple "cage-physics" picture that captures the
characteristic occupation fraction $p_{scale}$ and the asymptotic $1/p^2$
behavior for $p/p_{scale} \gtrsim 1$. We confirm that subdiffusive behavior of
tracer particles is controlled by the same $\hat{D}$ as particle transport.
