Regeneron Pharmaceuticals Licenses OriGene TrueClone Collection

"We believe that full-length cDNAs isolated from cDNA libraries are the most reliable source of authentic coding regions for our critical applications." said Drew Murphy, Vice President of Target Discovery for Regeneron. "The OriGene True Clone collection has proven to be an excellent source of full-length human cDNAs for use in Regeneron's protein expression and target validation platforms."

Exosomes – Novel markers for cancer diagnosis


Exosomes are lipid-bilayer-enclosed extracellular vesicles in bodily fluids. The composition of proteins, nucleic acids, and lipid in exosomes is reflective of cell functions and conditions. An increasing number of exosomal proteins have been found to be potential biomarkers for cancers and other diseases.

Exosomes play a vital role in cellular signaling in both normal physiology and disease states, particularly cancer. Exosomes are powerful progenitors in altering target cell phenotypes, particularly in tumorigenesis and cancer progression, with the ability to alter tumor microenvironments and to assist in establishing the pre-metastatic niche. Many aspects of exosomes present them as novel means to identify cancer biomarkers for early detection and therapeutic targets, and using intrinsic and engineered characteristics of exosomes as therapeutic devices to ameliorate the progression of the disease.

OriGene offers a wide range of ready-to-use reagents of cDNA/RNAi/protein/antibody to facilitate your exosomal biomarker research.
