On Dec 16, 2018, Broad Institute and Shanghai Model Organisms Center Inc (SMOC) has entered into a non-exclusive license agreement under which Broad has granted SMOC worldwide rights to commercialize a service platform for genetically modified mouse models under Broad's intellectual property.
詳細At GenoBioTX, we understand that the lengthy wait times for gene-modified mouse models can hinder your research progress. Traditional methods often require 6-9 months, leading to delays and increased costs. That’s why we’re thrilled to introduce our innovative service designed to streamline this process and deliver results faster.
