    Inventors: Michael Chorev, Jose Alberto Halperin
  • Patent number: 10309973
    Abstract: The present invention provides compounds that are surrogates of post-translationally modified proteins and uses thereof. Numerous diseases are associated with post-translationally modified proteins that are difficult to obtain in homogenous form and in quantities needed for immunization and use as convenient standards, calibrators, and/or reference compounds that facilitate the detection and analysis of endogenous post-translationally modified proteins. The surrogate compounds of the invention typically comprise antigenic epitopes (one of which carries a post-translational modification) that are tethered by a flexible and hydrophilic linker. The resulting compound behaves like a surrogate of the post-translationally modified protein because it preserves the character of the included antigens and allows recognition by specific antibodies targeting the individual antigens.

  • Patent number: 9952200
    Abstract: A method for determining the translation initiation inhibitory potency of a composition having an unknown level of translation initiation inhibitory activity which comprises contacting an eI-F2?-WT cell with said composition for a time and at a temperature effective to inhibit proliferation of said cell, measuring the level of inhibition of proliferation of said eIF2?-WT cells induced by said sample and comparing the level of inhibition of proliferation induced by said sample with the level of inhibition of proliferation induced by a standard having a known amount of said activity, the amount of said translation initiation inhibitory activity in said sample being proportional to the level of inhibition of proliferation of said eIF2?-WT cell.
