Host cell proteins (HCPs) are process-related protein impurities that are produced by the host organism during biotherapeutic manufacturing and production...

impurities termed host cell proteins also arrive in the final product in trace amounts. The oldest and most widely used expression systems are cell-based and...

recombinant DNA result in specific protein products. The major by-product, termed host cell protein, comes from the host expression system and poses a threat...

animals playing host to parasitic worms (e.g. nematodes), cells harbouring pathogenic (disease-causing) viruses, or a bean plant hosting mutualistic (helpful)...

biology, cell signaling (cell signalling in British English) is the process by which a cell interacts with itself, other cells, and the environment. Cell signaling...

cycle when traveling between host cells. Not all viruses have envelopes. A viral envelope protein or E protein is a protein in the envelope, which may be...

of their mRNA into viral proteins, but use proteins encoded by the host cell for this purpose. Most viral structural proteins are components for the capsid...

well as the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled...

entry of its DNA to the hosts. Bacteriophage Lambda binds to an E. coli cell by means of its J protein in the tail tip. The J protein interacts with the maltose...

which an exterior viral protein stably interacts with a host cell protein—determines cell tropism. In the case of HBV the host receptor is human sodium...
