No immediate clinical implications; leaves open whether in vitro virus libraries will advance protein engineering research.
The in vitro virus method allows for a massive library of protein variants (10^12), significantly larger than phage display, providing a powerful tool for evolutionary molecular engineering.
Nemoto et al. (1997) studied this question. In vitro virus construction (mRNA-protein covalent binding via puromycin) vs. Phage display was evaluated on Bonding efficiency. Construction of an 'in vitro virus' achieved a bonding efficiency of approximately 10%, yielding a population of 10^12 protein variants, which is 10^4 times that of phage display.
