Do quark mass effects survive in the high-Q limit of DIS?

Quark mass effects are analyzed at high Q2 in the current fragmentation region of DIS. It is found that the linear combination F 2 -2.75F c 2 scales at large Q2 and small x. We obtained a lower bound for the ratio F c 2/F 2 which lies very close to the data from HERA.
