Instantons, Holomorphic Bundles and the Bar Construction

One version of the Kobayashi-Hitchin correspondence relates moduli spaces of instantons on blow ups of $C^2$ trivialized at $\infty$, with holomorphic bundles on blow ups of ${\mathrm{CP}}^2$ framed on a line. In the rank stable limit these moduli spaces can be described using a bar construction.
