purposes are of utmost importance. Further, therapeutic biomolecules have a higly complex composition and structure. Moreover, the products may vary in structure due to the complexity of cell culture and purification processes. Various modes of CE offer several possibilities for biopharmaceutical analysis including glycosylated therapeutic proteins, monoclonal antibodies, pharmaceutical and biopharmaceutical impurities. CZE has been used for proteins as long as there are differences in charge: frictional grag ratios. The acceleration and rapid success of Human Genome Project was possible due only to the introduction of CEbased sequencers. CE application in biotechnology

(5p) GPCRs are integral membrane proteins that possess seven membrane-spanning domains ortransmembrane helices (Figure 1). The extracellular parts of the receptor can be glycosylated. These extracellular loops also contain two highly-conserved cysteine residues that form disulfide bonds to stabilize the receptor structure. Some seven-transmembrane helix proteins (channelrhodopsin) that resemble GPCRs may contain ion channels, within their protein. Suurem osa imetajate rakupinnaretseptoritest on G-valguga seotud retseptorid (GPRCd). Sellised retseptorid on funktsionaalselt kompleksis trimeersete GTPaasse aktiivsusega valkudega. Ligandi
