For a particular choice of parabolic subalgebra of gl(2n) we construct a parabolic 2-Verma module and use it to give a construction of Khovanov-Rozansky’s HOMFLY-PT and glN link homologies. We use our version of these homologies to prove that Rasmussen’s spectral sequence from the HOMFLY-PT-link homology to the gl(N) -link homology converges at the second page, proving a conjecture of Dunfield, Gukov and Rasmussen
