摘要:
The present invention relates to transgenic non-human animals that are engineered to contain human immunoglobulin gene loci. In particular, animals in accordance with the invention possess human Ig loci that include plural variable (VH and Vκ) gene regions. Advantageously, the inclusion of plural variable region genes enhances the specificity and diversity of human antibodies produced by the animal. Further, the inclusion of such regions enhances and reconstitutes B-cell development to the animals, such that the animals possess abundant mature B-cells secreting extremely high affinity antibodies.

摘要:
A process for the expression and purification of membrane associated proteins is provided. A process for the expression and purification of membrane proteins such as G-protein coupled receptors is provided. A hybrid polypeptide is constructed from a protein of interest and a peptide tag from the amino-terminus extracellular domain of rhodopsin. A method for purifying the hybrid protein using the rhodopsin tag is provided. Methods of detecting the expressed hybrid are also provided.
