Let $A$ be a $C^*$-algebra. We know that $A$ admits a natural operator space structure, namely the operator space structure induced by any faithful $*$-representation of $A$ into some $B(\mathcal H)$ for some Hilbert space $\mathcal H.$ Now consider the opposite $C^*$ algebra $A^{op}$ which is the same as $A$ but multiplication reversed. Now $A^{op}$ has a natural operator space structure as well. 1. Is it true that the matricial norms are given by $\|[x_{ij}]_{i,j=1}^n\|_{M_n(A^{op})}=\|[x_{ji}]_{i,j=1}^n\|_{M_n(A)}$? 2. Suppose $A$ and $A^{op}$ is isomorphic as $C^*$-algebras then there exists some constant $C>0$ such that for all $n\geq 1$ and $[x_{ij}]_{i,j=1}^n\in M_n(A)$ we have $\|[x_{ij}]_{i,j=1}^n\|_{M_n(A)}\leq C \|[x_{ji}]_{i,j=1}^n\|_{M_n(A)}$?
