May 4, 2016 at 15:42 comment added Bill Johnson The relevant Kalton paper is Kalton, N. J. Spaces of compact operators. Math. Ann. 208 (1974), 267–278. It is arguably overkill to quote this paper because a standard gliding hump argument gives the non existence of an isomorphic copy of $c_0$ in $K(c_0,\ell_1)$.
May 4, 2016 at 15:38 comment added Bill Johnson $K(c_0,\ell_1)$ is separable, Jochen; in fact, $e_j \otimes e_i$ is a Schauder basis for it.
May 4, 2016 at 8:45 comment added Jochen Wengenroth Could you please give a reference for Kalton's result and elaborate why $K(c_0,\ell_1)$ cannot contain $\ell_\infty$?
