n.1.(Biochem.) the process of testing samples of mixtures which are active in a screening process, so as to recognize and eliminate from consideration those active substances already studied; - a stage subsequent to the preliminary screening in the process of discovery of new pharmacologically active substances in mixtures of natural products; - also called counterscreening. See screening.

UPLC-MS technique is very power full technique which help us in identifying compounds with satisfactory knowledge for efficient dereplication. It has several advantages over conventional HPLC-MS which includes quality of results, efficiency, speed, resolution, sensitivity, pressure limit, versatility of solvents used and column chemistry.
ARM can uniformly distribute the requests of hotspot data to other storage nodes by performing active replication and efficiently utilize storage resources by executing on-demand dereplication. By considering both short-term and long-term data access behaviors, ARM achieves excellent load balancing by establishing optimal number of copies for hotspot data on adequate storage nodes.
Based on the microscopic and cultural characteristics, 54 different actinomycete isolates were selected after dereplication of 18 isolates.
