| abstract |
The invention provides several new transporter proteins, nucleic acids encoding them and methods of using the transporters to screen agents, conjugates or conjugate moieties, linked or linkable to agents, for capacity to be transported as substrates through the transporters. The invention also provides methods of treatment involving oral delivery of agents that either alone, or as a result of linkage to a conjugate moiety, are substrates of one of the transporter. |
